Main Idea:
The lungs are the second largest organ in the body and have many impressive functions as the primary organs of the respiratory system.
Supporting Detail:
The lungs work with the heart to draw in oxygen, which is carried by red blood cells throughout the body.
Supporting Detail:
The diaphragm, a large muscle below the lungs, works with them to move air in and out of the body, while air travels through the trachea, pharynx, larynx, and bronchi before reaching the lungs.
Supporting Detail:
The rib cage protects the delicate respiratory system, and the lungs' branching bronchi resemble trees as they expand into the spongy tissue of the left and right lungs.
