Terms to know

Alveoli
Tiny air sacs at the end of the bronchioles (tiny branches of air tubes) in the lungs. The alveoli are where the lungs and the bloodstream exchange carbon dioxide and oxygen. Carbon dioxide in the blood passes into the lungs through the alveoli. Oxygen in the lungs passes through the alveoli into the blood.
Bronchioles
A tiny branch of air tubes in the lungs.
Lobe
A portion of an organ, such as the liver, lung, breast, thyroid, or brain.
Lungs
One of a pair of organs in the chest that supplies the body with oxygen, and removes carbon dioxide from the body.
Lymph Nodes
A rounded mass of lymphatic tissue that is surrounded by a capsule of connective tissue. Lymph nodes filter lymph (lymphatic fluid), and they store lymphocytes (white blood cells). They are located along lymphatic vessels. Also called lymph gland.
Thoracic Diaphragm
The thin muscle below the lungs and heart that separates the chest from the abdomen.
Trachea (Windpipe)
The airway that leads from the larynx (voice box) to the bronchi (large airways that lead to the lungs). Also called windpipe.
