General Anatomy: Cardiovascular System

Capillaries facilitate the exchange of oxygen, nutrients, and waste between the blood and body tissues.

The atria are the receiving chambers of the heart that collect blood before passing it to the ventricles.

Capillaries allow for the exchange of nutrients and waste products between blood and tissues.

Sinusoids, which allow for extensive exchange of substances, are present in the liver and spleen.

Capillaries are tiny vessels that allow exchange of nutrients and waste between blood and tissues.

Venules are small veins that merge into larger veins, ultimately forming the vena cava.

Veins collect blood from tissues and return it to the heart.

Arterioles are minute branches of arteries that regulate blood flow into capillaries.

Arteries are distributing channels that transport blood away from the heart.

The heart consists of four chambers—two atria (receiving chambers) and two ventricles (pumping chambers).

The heart is responsible for pumping blood throughout the body.

The cardiovascular system transports nutrients to various parts of the body and removes waste products.
