PULMONARY SYSTEM
Breathing starts with your nose or mouth, and travels down the back of your throat and into your windpipe, the trachea. Your trachea then divides into air passages called bronchial tubes. For the lungs to perform their best, airways need to be open during inhalation and exhalation and free from inflammation, swelling, excess, or abnormal amounts of mucus.
The bronchial tubes pass through the lungs; divide into smaller air passages called bronchioles. The bronchioles end in tiny balloon-like air sacs called alveoli. Alveoli are surrounded meshes of tiny blood vessels called capillaries. Oxygen from inhaled air passes through the alveoli walls and into the blood. Once collecting oxygen, blood leaves the lungs and carried to the heart. Heart then pumps it through your body to provide oxygen to the cells of your tissues and organs.
As the cells use the oxygen, carbon dioxide is produced and absorbed into the blood. Blood then carries carbon dioxide back to the lungs through capillaries, this is removed from the body when exhaling. The breathing process is aided by a large dome-shaped muscle under the lungs called the diaphragm.
While breathing, the diaphragm contracts downward, creating a vacuum that causes a rush of fresh air into the lungs. The opposite occurs with exhalation, where the diaphragm relaxes upwards, pushing on the lungs to deflate.
Respiratory System has small hairs in your nose, called cilia, help filter out large particles. Cilia are also found along your air passages and move in a sweeping motion to keep the air passages clean. If harmful substances, such as cigarette smoke is inhaled, the cilia stop functioning properly, causing health problems like bronchitis. Mucus produced by cells in the trachea and bronchial tubes keeps air passages moist and aids in stopping dust, bacteria, viruses, allergy-causing substances, and other substances from entering the lungs.

Pulmonary Fibrosis, AKA, 'Air Hunger,' is starving yourself from oxygen. One does not overeat to compensate, but to eat all the necessary vitamins and nutrients.
