Definitions of some parts of the lungs The two main air passages into the lungs. The main muscle used for breathing; separates the chest cavity from the abdominal cavity. A flap of cartilage that prevents food from entering the trachea (or windpipe). The tube through which food passes from the mouth down into the stomach. The muscular organ that pumps blood throughout the body. Thin sheets of muscle between each rib that expand (when air is inhaled) and contract (when air is exhaled). Voice box. The two organs that extract oxygen from inhaled air and expel carbon dioxide in exhaled air. These muscles help move the diaphragm up and down for breathing. Interior area of the nose; lined with a sticky mucous membrane and contains tiny, surface hairs called cilia. Located at the entrance of the nose, these hairs trap large particles that are inhaled. Air spaces within the skull. The throat. Covering the lung and lining the chest cavity, this membrane has 2 thin layers. Pulmonary arteries carry deoxygenated blood from the heart and lungs; pulmonary veins carry oxygenated blood back to the heart. Area of the brain that controls breathing. Bones attached to the spine and central portion of the breastbone, which support the chest wall and protect the heart, lungs, and other organs in the chest. Tube through which air passes from the nose to the lungs (also known as the windpipe).

The respiratory system is like an outer-space oxygen tank refilling station. What the station would be, hypothetically, is a station where astronauts would go to refill oxygen tanks in outer space. The following table shows the comparisons between the steps in the human respiratory system to the outer-space oxygen station. Oxygen taken from Earth to be transported to the space station. || Surrounding air: Oxygen taken from the air to be used in respiration || Carries oxygen reserves from Earth to the outer-space station. || Trachea: Allows air to pass through the pharynx to the lungs. || Where the oxygen reserves to fill the oxygen tanks of the astronauts is stored. Holds the oxygen dispensing machines. || Lungs: From which the right and left principle bronchi branch off smaller and smaller into bronchioles. The bronchioles lead to alveoli ducts, holding millions of alveoli sacs. || Gives oxygen to an astronauts oxygen tank. || Alveoli: Oxygenates red blood cells. || Provides astronauts with air to breath. || Red blood cells: Provide oxygen for aerobic cellular respiration. || [|Picture of Oxygen TAnks] Looking at the table above, it can be seen that a hypothetical outer-space station for oxygen refill is similar to how the human respiratory system works. Both the station and the human respiratory system aim to provide oxygen so that a human body would be able to live and operate. This analogy is not entirely correct in a microscopic point of view though. The process of gas exchange is not correct by not have CO 2 exchanged for the oxygen in at the oxygen dispensing machine/alveoli, but on a larger scale and only looking at the basic functions of the structure of both columns, I think it is a fair comparison.
