Lungs In this research project, I am going to talk what the lungs are, why they are important and what they do. I am also going to be talking about how the lungs work, problems that can happen in the lungs, the location of the lungs, and more. Your lungs are organs in your chest that allow you and your body to take in oxygen from the air. They also help you remove carbon dioxide, which is a waste gas that can be toxic, from your body. The lungs work after you inhale through your mouth or nose. The air travels down the back of your throat and then it passes through your voice box and into your windpipe. Your trachea, which is an anatomical structure used for breathing, is divided into two air passages called the bronchial tubes. One of the bronchial tube leads to the left lung and the other one lead to the right lung. For the lungs to do their job very well, the airways have to be open during inhalation and exhalation. They also need to be free from swelling and a lot of mucus. Your right lung has 3 sections called lobes, which is a little bit larger than the left lung, which has only 2 lobes instead of 3. The bronchial tubes divide into smaller air passages called the bronchi, and then into bronchioles. At the end of bronchioles are tiny air sacs called alveoli, where oxygen is transferred from the air you inhale to your blood. The average adult’s lungs contain about 600 million of these structures. Everyone has millions of alveoli in our lungs. There are enough alveoli in one lung to cover a tennis court! The alveoli are where the gas exchange takes place. The air sacs are surrounded by blood vessels that connect to the heart. The ones that link to the pulmonary arteries carry deoxygenated blood that needs to be refreshed.... ... middle of paper ... ... When you take part in certain exercises (like biking, running, or swimming, for example), your lungs require more air to give your cells the extra oxygen they need. As you breathe more deeply and take in more air, your lungs become stronger and better at supplying your body with the air it needs to succeed. Keep your lungs healthy and they will thank you for life! Whether we are asleep or awake, we don’t have to think about breathing. It is so important but it happens automatically. If we didn’t breathe, we couldn’t live.

When you breathe in, air containing carbon dioxide (CO2) and oxygen (O2) it moves down your trachea; a tunnel containing cartilage and smooth tissue. Air then travels through two hollow tubes called bronchi; narrow branches lined with smooth muscle, mucosal and ringed cartilage to support the structure. The bronchi divide out into smaller tunnels called bronchioles; are small branches 0.5-1mm, lined with muscular walls to help dilate and constrict the airway. At the end of the bronchioles are little air sacs called alveoli; which assist in gas exchange of O2 and CO2. (Eldridge, 2016) Towards the end of alveoli are small blood vessel capillaries. O2 is moved through the blood stream through theses small blood vessels (capillaries) at the end of the alveoli and the CO2 is then exhaled. (RolandMedically,
Breathing is made of two separate acts, inspiration (breathing in) and expiration (breathing out). The muscles in the chest act to expand and contract the chest cavity, causing the lungs to fill or empty. There is a pause between inspiration and expiration and that pause is shorter during fast
Blood vessels such as arteries and veins “transport oxygen, nutrients, hormones, and cellular waste products throughout the body” Taylor (2017). The cardiovascular system and respiratory systems work together to deliver oxygen to the body. During inspiration air enters through the nose or mouth. Air travels through the pharynx, which is superior to the larynx, and then into the trachea. The lungs are inferior to the trachea.
both these sysmtems work with one another to ensure that organs tissues in the body are supplied with an adequate amount of oxygen, and that carbon dioxide can be removed. firstly through the respiratory system, oxygen is inhaled through the nose and mouth, the oxygen is will travel down the trachea, the rachea divides into the bronchial tubes which enters the lungs. the bronchi divides into smaller branches known as the bronchioles, which have tiny air sacs called alveoli on the end. The alveoli is surrounded by thin blood capillaries, the wall of the capillaries is a single layer of cells. These thin walls allow gas exhange to take place. Oxygen will be diffused in the capillaries and will go into the red blood cells, where it will then be transported back to the heart. carbon dioxide will be diffused though the capillary walls into the alveoli, in an opposite path than oxygen. carbon dixoxide will be released in the lungs and through exhalation the carbon dioxide will be removed.The right atrium of the heart will supplied with de-oxygenated blood by the superior and inverior vena cava. The right atrium will pump the de-oxygenatd blood via the atrioventricualr valve until it reaches the right ventricle. the right ventricle will pump the de-oxygenated blood via the pulmonary semi-lunar valve, which will carry the blood pass through the pulmonary arteries unti it reaches the lungs. these veins from the lungs will carry oxygenated blood to the right atrium. the right atrium will now pump this fresh oxygenated blood past the aventricular valve so it can enter the left ventricle. the left ventricle the thickest out of the four chambers and will pump, so that oxygenated blood is supplied to all the organ tissues in the
This section you will learn how the respiratory system works. Organs in your body are responsible for you to inhale oxygen and exhale carbon dioxide (zimmermann, Kim Ann). Red blood cells collect oxygen and bring it to the areas needed, while thats happening carbon dioxide is being collected and gets carried back to lungs and get exhaled (zimmermann, Kim Ann). When you breathe the air goes in through your nose or mouth and travels through different tubes that lead to your lungs (zimmermann, Kim Ann). There are lobes on each lung that are called alveoli, when the air gets to these the exchange of oxygen and carbon dioxide happens(zimmermann, Kim Ann). Many different diseases and/or conditions can occur, some diseases are influenza, bacterial pneumonia, etc… (zimmermann, Kim Ann).
The lungs are a vital part of the respiratory system, a group of organs and tissues that work together to help humans breathe. The system’s main job is to move fresh air into the body while removing waste gases. Lungs are important because every cell in the body needs oxygen to live. The air we breathe contains oxygen and other gases. Once in the lungs, oxygen is moved into the bloodstream and carried throughout the human body. The bloodstream then carries the waste gas back to the lungs where it is removed from the blood stream and then exhaled. The lungs and respiratory system automatically perform this vital process, called gas exchange (American Lung Association). Lungs contain millions of air sacs called alveoli. With each breath,
The lungs helps primarily to exchange gases, the carbon dioxide byproduct produced from the body with the fresh oxygen
To explain normal functioning of the respiratory system, it is best to know that the respiratory system in human beings is comprised of the upper respiratory tract that consists of the nasal passages, pharynx and the larynx. The lower respiratory tract is composed of the trachea, the primary bronchi and the lungs. The primary function of the respiratory system is to supply oxygen to the blood in the body. Oxygen is delivered to all parts of the body. The respiratory system does this while breathing is taking place. During the process of breathing, one inhales oxygen and exhales carbon dioxide. This exchange of gases within the thoracic cavity takes place at the alveoli within the body (Grant, 2004). The average adult's lungs contain about 600 million of these air-filled sacs that are surrounded by capillaries (Grant, 2004). The inhaled oxygen passes into and through the alveoli and is diffused through the capillaries into the arterial blood. Meanwhile, the waste-rich blood from the veins releases the carbon dioxide into the alveoli. The carb...
The respiratory system is made up of the trachea, lungs, air sacs, diaphragm, bronchi, and bronchioles. The respiratory system provides the route by which the supply of oxygen present on the atmosphere gains entry to the body and also an opposite route for the excretion of carbon dioxide. Exchange of gases between an organism and its external environment is known as external respiration whereas that between the blood and the cells internal respiration. First of all, air is breathed into the body via the mouth and the nose. The air travels through the voice box (pharynx) down to the windpipe (trachea) and then through the bronchi into the lungs. The Carbon dioxide which is not needed is therefore required to be exhaled. This happens in a reverse process. However, the air taken in...
Healthy lung tissue is predominately soft, elastic connective tissue, designed to slide easily over the thorax with each breath. The lungs are covered with visceral pleura which glide fluidly over the parietal pleura of the thoracic cavity thanks to the serous secretion of pleural fluid (Marieb, 2006, p. 430). During inhalation, the lungs expand with air, similar to filling a balloon. The pliable latex of the balloon allows it to expand, just as the pliability of lungs and their components allows for expansion. During exhalation, the volume of air decrease causing a deflation, similar to letting air out of the balloon. However, unlike a balloon, the paired lungs are not filled with empty spaces; the bronchi enter the lungs and subdivide progressively smaller into bronchioles, a network of conducting passageways leading to the alveoli (Marieb, 2006, p. 433). Alveoli are small air sacs in the respiratory zone. The respiratory zone also consists of bronchioles and alveolar ducts, and is responsible for the exchange of oxygen and carbon dioxide (Marieb, 2006, p. 433).
There are three parts that make up the respiratory system; muscle, lungs and the airway (respiratory system 2017). Although, there are three main parts the main organ is the lungs. The respiratory system delivers air to the alveoli, while giving and removing Carbon dioxide. Asthma is one of the many respiratory diseases. From personal experience, Asthma can affect one’s life in many ways. Asthma is when your airway is inflamed and produces a lot of mucus which makes it hard for one to breathe. Many are affected by respiratory diseases, because it effects their everyday
Air flows through the nose or mouth, down the throat toward the voice box and goes down the tracheal. Air continues until it finally gets to the air sac called the alveoli where oxygen is taken in to the blood. The air we breathe comprises of many tiny particles that must be removed before the air reaches the air sacs located deep in the lungs. “Dirty particles are partly cleaned by the hairs in the nostrils, and located in the airways are glands which produce sticky fluid called mucus” (UF 2015 URL). This mucus hides the airway by trapping dirt and germs found in it, the tiny broom-like structures called the cilia, clears the dirty mucus from the airways. This sweeps the mucus up near the throat where it can be spit out. Hydration also plays an important role in the lungs. If the air breathe in is too dry, it can damage the tiny sacs in the lungs. Thus, the air must be made moist by absorbing water. Normal lung function is also very vital with the breathing mechanism. The chest contains two lungs and is protected by the ribcage. The purpose of the lungs is to bring oxygen into the body which provides the body with energy, and the removal of carbon dioxide which is considered the waste product of the body. When asthma occurs, it affects the respiratory system, causing a contraction and tightening of the tracheal openings and inflammation of the mucus lining. A summary from Gorman, Christine states that “infection introduced into the body through bronchial passage causes the body to respond by activating defense cells from the immune system. Thus, causing the airways to be inflamed and contracting the surrounding muscles” (P.61-62). An asthmatic patient has airways that are much more sensitive and responsive than airways of a normal person. They tend to become irritated very easily, making the functions of the airways and mucus glands to become hyperactive. When an individual with
The larynx prevents food and liquids from traveling down the air path ways which could result in choking. From the larynx, Bronchi trachea splits into two bronchi each leading to a lung, each lung is divided into lobes. The right lung has three lobes and the left has two lobes. The right lung is slightly larger than the left lung. The two lungs are mainly made of up connective tissue, which gives them their soft and spongy texture. The bronchi branch are smaller and are called bronchioles which are divided many more times in the lungs. The lungs is made up of connective tissue, blood, lymphatic tissue, air pathways and alveoli are at the end of the branches inside of the lungs. The alveoli sends oxygen and removes carbon dioxide. This is a basic view of how the respiratory system functions and if the respiratory system doesn’t do its job then this could lead to infectious diseases of the respiratory
The human lungs are a pair of large, sponge like organs that are optimised for gas exchange between the blood and oxygen. The human body requires oxygen in order to survive and function. The lungs are responsible for providing vital oxygen while also removing the carbon dioxide before hazardous levels are reached within the body.
The roles of the circulatory and respiratory system both carry important responsibilities and are essential in their jobs to the human body. The circulatory system is one, if not the, most important system in the human body. The circulatory system is made up of the heart, blood, and blood vessels. Within the blood vessels, there are three types: arteries, veins, and capillaries. The heart is an organ made up of cardiac muscle that has a role similar to a pump. When the muscles in the heart contract, it pumps fresh blood away from the heart, through a main artery called the aorta, and to the organs and cells of the body. Nutrients and oxygen then enter the cells through diffusion of the tissues. The respiratory system transports oxygen to the circulatory system. When transporting oxygen to the circulatory system, this will in turn transport oxygen to the rest of the cells in the body. Aside from transporting oxygen to the body, the respiratory system also plays a role in the removal of carbon dioxide and other contaminants in the body. These two systems effectively and efficiently work together in order to supply the body with oxygen and remove carbon dioxide and any other
