Respiratory System
The respiratory system is a group of organs that take in oxygen and get rid of carbon dioxide. It is made of your nose, throat, lungs, and passageways leading to lungs. Its main processes are respiration and breathing. Your body needs oxygen to get energy from food. It is made out of connective, epithelial, and nervous tissues. As an example, it uses nervous tissue to tell your body to breath. Respiration is the process of how your body receives and uses oxygen. It is also how your body releases carbon dioxide and water. One part of it is breathing, the other is cellular respiration(glucose+ o2- co2+ H20+ energy). On the other hand, there's breathing. One part of this is respiration. There's inhaling, which is when air enters lungs through mouth and nose; you breathe in oxygen. Then, there's exhaling. This is when air exits lungs through mouth and nose; breath out carbon dioxide. The diaphragm is a muscle that controls lung size and breathing. Inhaling(inspiration): 1) diaphragm contracts 2) increases space 3) decreases pressure 4) air pulled in. Also, there's exhaling(expiration): 1) diaphragm relaxes 2) decreases space 3) increases pressure 4) air pushed out. Moving on, the nose, pharynx, and larynx all work together. The nose is the main passage in and out of the respiratory system. From the nose, air enters the pharynx(throat). Air then travels through the larynx, trachea, and then to your lungs. The trachea(windpipe) is guarded by the larynx, it also keeps air traveling from mouth to lungs. The lungs are a sponge- like organ that's made of epithelial tissue. Your left lung as 2 lobes, whereas your right has 3. It is also where gas exchange occurs(o2 in, co2 out). Carbon dioxide is a waste product from cellular respiration. Your alveoli is made of epithelial tissue and covered in blood capillaries. As blood passes over alveoli, carbon dioxide and oxygen are exchanged.
"Laughing is also good for your respiratory system."~ Allen Klein- an American author Diseases:COPD- This is a progressive disease that makes it increasingly difficult for sufferers to breath.
Asthma- This is a chronic inflammation of the lung airways that causes coughing, wheezing, chest tightness or shortness of breath. These signs and symptoms may be worse when a person is exposed to their triggers. Lung cancer- This is often associated with smoking, but the disease can affect non-smokers as well. Every year, about 16,000 to 24,000 Americans die of lung cancer, even though they have never smoked. Like all cancers, lung cancer is caused by the uncontrolled growth of abnormal cells. |
"Millions of people with respiratory diseases have relied on oxygen equipment, delivered to their homes, to help them breathe."~ Charles Duhigg- an American journalist In this video, you will learn about respiration, parts of the respiratory system, breathing, what some of the parts do, the lungs, how your body compromise during physical activity, and it also goes deeper into other parts of it for example, the cilia.
