1. What is the primary function?Conduit for oxygenated blood from the heart to systemic circulation
2. What is the key physiological role?Regulation of blood pressure through vasoconstriction and vasodilation
3. What are arteries and what do they do?Arteries are strong tubes that carry oxygen-rich blood from the heart to all parts of the body. They keep the blood moving so every cell gets the oxygen it needs.
4. Why are arteries called “super highways” for blood?Because they are built to handle the high pressure from the heart’s pumping and have stretchy walls that expand and recoil, keeping the flow smooth.

Vasoconstriction: The narrowing of blood vessels, typically to increase blood pressure and reduce flow.
Vasodilation: The widening of blood vessels, typically to decrease blood pressure and increase flow.
Atherosclerosis: A disease where plaque builds up inside arteries, hardening and narrowing them.
