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 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.
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
In the lungs gas exchange occurs to re-oxidize the blood. Air travels through the respiratory tract to reach the lungs and back up to be exhaled into the environment. At the termination point of the respiratory tract lays the alveoli. The alveoli have a sac-like structure. In biological systems, the structure and functions of components are related. The alveoli have a structure specialized for efficient gaseous exchange. In the structure of the alveoli (alveolus), it looks as if it has the form of a hollow cavity that is paired with elastic fibers...
The chief organs of breathing are the lungs. There are two pyramid-shaped structures that lie in the chest, or thoracic, cavity. Another important organ in respiration is the powerful dome-shaped muscle called the diaphragm, which forms the floor of the chest cavity.
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
The skeleton of the respiratory system is important for keeping the organs and structures safe. The skeleton is the spinal column, pelvic girdle, the rib cage, the clavicles, the scapulae, and the skull. The skeleton of the respiratory system and the soft tissues allow the muscles of the respiratory system to move gasses in and out of the lungs and respiratory passages. Bringing air and gas into the system is called inspiration while forcing out gas and air is expiration. One of the primary muscles of inspiration is the diaphragm. It is located right under the lungs and when it contracts, it flattens part of the thorax which flattens the abdomen and makes the lungs larger. That is why it is called diaphragmatic or abdominal movement. Changing the dimensions of the thoracic cavity with several other muscles by acting on the ribs is called costal movement. “Pump Handle Movement” shifts the thorax up and forward by movement of ribs one through six. The other is called “Bucket Handle Movement” which shifts up and laterally by movement of ribs seven through ten. Intercostal muscles allow the ribs to move in that way. Primary muscles are used for normal
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
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.
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...
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).
Have you ever felt like you were out of breath…. This all falls under the respiratory system. The respiratory system is divided into two different portions. The first is made up of the upper airway and the second portion is the lower airway. Muscles, respiratory distress, failure, hypoxic drive, extra.
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
