Understand the function of each type of blood vessel: Arterioles, Arteries, Veins, and Capillaries.
Arterioles are small branches of arteries that lead to capillaries and are primarily involved in regulating blood flow and pressure.
Arteries are blood vessels that carry blood away from the heart to various parts of the body. They have thick walls to handle high pressure.
Capillaries are the smallest blood vessels where the exchange of gases, nutrients, and waste occurs between blood and tissues.
Veins are blood vessels that carry blood back to the heart. They have thinner walls and larger lumens compared to arteries, allowing them to hold more blood, thus acting as a blood reservoir.
