Breathing, coughing, sneezing… All these actions are controlled by the fascinating respiratory system. Your respiratory system does all sorts of things in order to keep the intake of oxygen and exhale carbon dioxide running smoothly. After reading this piece, maybe you will think differently of the respiratory system.
When you inhale, the air travels from the mouth and nose to the larynx and down the trachea, a tube that is right next to the passage foods take. The trachea stretches down to the chest cavity, and splits into two tubes called the bronchi. The bronchi then splits into bronchial tubes which then split into more smaller tubes, connecting to small sacs called alveoli. The oxygen in the alveoli diffuses into the bloodstream while carbon dioxide, the waste from the body’s tissues, would diffuse into the alveoli to be exhaled out. The alveolar walls are extremely thin, in order to make the gas exchange efficient and fast. Because alveoli have lots of capillaries around them, the oxygen would be quickly transferred into the bloodstream, which also means carbon dioxide in the bloodstream would also be quickly transferred into the alveoli. The rib cages and diaphragm play a key role in the respiratory system. The rib cage is raised by external intercostal muscles when breathing in, and lowered by internal intercostal muscles when breathing out. The rib cage would also protect the lungs and the heart so that when the person falls the fragile organs would be protected.
There are many crucial parts and functions of the respiratory system that keep the system and the body healthy and normal. Cartilage plays a huge role in the respiratory system. A flap of cartilage called epiglottis prevents food from entering the trachea....

...ulated mucus thinner, which would help make breathing easier. Including plants in your house would allow you to have a better breathing environment. Wash your hands constantly not just to keep your lungs healthy, but to make the other systems healthy as well. Exercise when the air is clean and not polluted. Check the API to limit physical activities when the API is high. The respiratory and other systems are created just to provide for our needs, every aspect is considered, it is like some really smart being created these systems since there is a small chance of having problems with these systems, without actually doing something bad to your body. If you ever get into smoking, think twice, think about what is written in this piece. Think twice when you do something that might affect your respiratory system, because you will always want it in the best condition.
The respiratory system has the function of getting rid of carbon dioxide and acquiring oxygen. It works closely with the circulatory system to feed the body the proper amounts of oxygen it needs to function efficiently. The respiratory system of an American Mink is very similar to that of a human in spite of the fact that there are some minor modifications. Both Humans and Minks have two lungs, the right lung is larger and has three lobes and the left lung has two lobes. The reason why the left lun...
The respiratory system is the system for taking in oxygen and giving off carbon dioxide in organisms. The respiratory systems of California sea lions, king cobras, and bald eagles have a few similarities and differences, but they all allow the intake of oxygen for each organism.
The respiratory system undeniably serves a very important function in the body. Anyone who has had any event where they couldn’t breathe normally, or maybe not at all, recognizes the importance and mental peace that comes with being able to breathe stress free.
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).
Aim: The aim of this assignment will be to research the basic structure and function of Human Lungs and the respiratory condition known as asthma, and how its effects on the human lungs, looking at the causes and treatments used to prevent and treat the illness.
The Respiratory System 1. Define respiration. Respiration is the process of converting glucose to energy, which goes to every cell in the body. 2. Describe the organs of external respiration.
Every cell in the human body requires oxygen to function, and the lungs make that oxygen available. With every breath we take, air travels to the lungs through a series of tubes and airways. After passing through the mouth and throat, air moves through the larynx, commonly known as the voice box, and then through the trachea, or windpipe. The trachea divides into two branches, called the right bronchus and the left bronchus, that connect directly to the lungs. Air continues through the bronchi, which divide into smaller and smaller air passages in the lungs, called bronchioles. The bronchioles end in clusters of tiny air sacs, called alveoli, which are surrounded by tiny, thin-walled blood vessels called capillaries.
The circulatory system and respiratory system share a highly important relationship that is crucial to maintaining the life of an organism. In order for bodily processes to be performed, energy to be created, and homeostasis to be maintained, the exchange of oxygen from the external environment to the intracellular environment is performed by the relationship of these two systems. Starting at the heart, deoxygenated/carbon-dioxide (CO2)-rich blood is moved in through the superior and inferior vena cava into the right atrium, then into the right ventricle when the heart is relaxed. As the heart contracts, the deoxygenated blood is pumped through the pulmonary arteries to capillaries in the lungs. As the organism breathes and intakes oxygenated air, oxygen is exchanged with CO2 in the blood at the capillaries. As the organism breathes out, it expels the CO2 into the external environment. For the blood in the capillaries, it is then moved into pulmonary veins and make
The Circulatory System is a transportation and cooling system for the body. The Red Blood Cells act like billions of little mail men carrying all kinds of things that are needed by the cells, also RBC's carry oxygen and nutrients to the cells. All cells in the body require oxygen to remain alive. Also there is another kind of cells called white blood cells moving in the system. Why blood cells protect from bacteria and other things that are harmful. The Circulatory system contains vein arteries, veins are used to carry blood to the heart and arteries to carry the blood away. The blood inside veins is where most of the oxygen and nutrients are and is called deoxygenated and the color of the blood is dark red. However, blood in the arteries are also full of oxygen but is a bright red. The main components of the circulatory system are the heart, blood, and blood vessels.
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,

To prevent your lungs taking in debris and dust, the mammal has small hairs and produces mucus that catches it. A mammal’s airways are lined with tiny hairs which have the purpose of sweeping debris that the mucus has caught in a wave like motion to the top of the throat and this is then swallowed and further destroyed in the stomach. It is these features and adaptations which help to maintain a large surface area for gas exchange to occur as it prevents these bacterial products from sticking and gathering on the gas exchange surface. A mammal’s lungs are surrounded and protected by a muscle structure called the rib cage which allows the lungs to move in and out as the rib cage provides a canopy for them. The diaphragm contracts to draw in the air and then relaxes pushing out, this ventilates the lungs. Tidal ventilation occurs as the air goes in and out the same way but this is similar to insects in the way that it isn’t the most efficient process as not all the air that is taken in with each breath is breathed out again as some of the oxygen has already been lost to the blood flow and not all the air taken in with each breath actually makes it to the gas exchange surface in the
The Mechanism and Regulation of Breathing Breathing is an involuntary movement that is controlled by the medulla, which is part of the hind brain. Air is sucked into the lungs. through an active process called inspiration. The external intercostals muscle contract and the internal intercostals muscle relax this causes. the ribs to be drawn upwards and outwards.
In conclusion, air pollution affects the immune system, making it weak and vulnerable to certain bacteria, illnesses, viruses and foreign invaders. Common diseases that are affected the most include asthma and allergies. Air pollution in general has been seen to modify the immune system's handling of particular allergens. The exposure to toxins like dioxin can cause serious health problems for people. Having long-term exposure to this toxin is connected to weakening of the immune system, as well as the nervous system, endocrine system and certain reproductive functions. Hence, everyone has a particular level and exposure of dioxins in the body. Improving air quality is the key answer to avoiding any type of development of disease, but it is a long term goal that will require the help and commitment at the national and global level.
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
