Respiratory System |
The respiratory system is a group of organs that take in oxygen and get rid of carbon dioxide. It is made of muscle, connective, and epithelial tissue. The system works with the muscular system to help move the lungs and works with the circulatory system to exchange blood and get rid of waste. It manly consists of the nose, throat, lungs, and other passageways. Respiration is the process of how the body gets and uses oxygen and releases carbon dioxide and waste. Breathing in one part of respiration. When you breath you inhale and exhale. When you inhale your diaphragm contracts, your lungs increase in space, and air is pulled in. When you exhale the diaphragm relaxes, your lungs decrease in space, and air is pushed out. There are three main passage ways. The nose, pharynx, and larynx. The nose is the main passageway in and out of the respiratory system. From the nose air enters the pharynx and then travels through the larynx to the trachea. The trachea is also known as the windpipe. It keeps air traveling to the lungs. The lungs are a sponge like organ made of epithelial tissue. It is where gas exchange occurs. Inside the lung the trachea splits into two section called bronchus, each bronchus leads into a lung, the bronchus branch into smaller bronchioles, and bronchioles split into alveoli. Alveoli are tiny air sacs where air exchange occurs. Overall, the Respiratory system helps you maintain homeostasis by making oxygen to get energy from food and getting waste out and new oxygen in.
