The respiratory system allows for the body’s involvement in the process of respiration, which allows the body to intake oxygen and breathe. During respiration, oxygen is carried into the lungs and carbon dioxide is removed from them.
The main components of the respiratory system are the lungs, the bronchi, the trachea, the diaphragm, the mouth, and the nasal cavity.
The red blood cells, located in the lungs, transport oxygen throughout the body and simultaneously remove carbon dioxide wastes from the lungs upon exhale. The trachea is also known as the windpipe, which filters the air that is breathed into the body. The bronchi appear as an upside-down fork in the windpipe that carries oxygen directly to the lungs from the trachea. The diaphragm contracts, flattens out, and is pulled downward when air is breathed into the lungs; this air is forced out of the lungs with the amount of available space decreases when the diaphragm expands during exhale.
