The process where oxygen diffuses into the bloodstream and carbon dioxide diffuses out into the lungs.

To bring in oxygen and expel carbon dioxide.

Blood vessels that carry blood away from the heart.

To transport blood back to the heart.

Tiny sacs in the lungs where gas exchange occurs.

To contract and create negative pressure, pulling air into the lungs.

The loop of circulation that carries deoxygenated blood from the heart to the lungs and returns oxygenated blood back to the heart.

The loop of circulation that delivers oxygenated blood to the body and returns deoxygenated blood to the heart.

Small blood vessels where gas and nutrient exchange occurs between blood and tissues.

Plasma, white blood cells, and red blood cells.

The windpipe that brings air from the pharynx to the lungs.

The two main branches of the trachea that lead into the lungs.

The smallest branches of the bronchi, supported by smooth muscle.

A substance that reduces surface tension in the alveoli, preventing them from collapsing.

To drain excess plasma from interstitial fluid and return it to the bloodstream.

The chambers of the heart that receive blood from veins.

The chambers of the heart that receive blood from atria and pump it into arteries.

Valves that prevent backflow from the ventricles to the atria.

To prevent backflow from the ventricles to the arteries.

The artery that carries deoxygenated blood from the heart to the lungs.

The main artery that delivers oxygenated blood from the heart to the body.

The large veins that return deoxygenated blood from the body to the heart.

A hormone secreted by the kidney that stimulates red blood cell production.

A disease caused by abnormal hemoglobin that results in distorted red blood cells.

To play an important role in blood clotting.

The special type of epithelial tissue that lines the interior surface of blood vessels.
