Study Notes
Arteries
- Elastic arteries, which include the aorta, have many elastic layers in their walls.
- Elastic arteries allow for stretching and recoil with each heartbeat, maintaining a constant blood pressure.
Types of Blood Vessels
- There are three main types of blood vessels in the cardiovascular system: arteries, veins, and capillaries.
Medium Muscular Arteries
- The main component of the walls of medium muscular arteries is smooth muscle.
Oxygen Delivery
- Arterioles deliver oxygenated blood to capillaries.
Veins
- Veins return deoxygenated blood to the heart from the capillary beds.
