Cardiovascular
The term cardiovascular refers to the heart (cardio) and the blood vessels (vascular). The cardiovascular system includes:
- Arteries
- Arterioles
- Capillaries
- Heart
- Venules
The interior of the heart is composed of valves, chambers, and associated vessels.
The external structures of the heart include the ventricles, atria, arteries and veins. Arteries carry blood away from the heart while veins carry blood into the heart. The vessels colored blue indicate the transport of blood with relatively low content of oxygen and high content of carbon dioxide. The vessels colored red indicate the transport of blood with relatively high content of oxygen and low content of carbon dioxide.
