NEET PG DENTAL EXAM

Detailed explanation-1: -Arterioles are considered the primary resistance vessels as they distribute blood flow into capillary beds.

Detailed explanation-2: -Peripheral vascular resistance (systemic vascular resistance, SVR) is the resistance in the circulatory system that is used to create blood pressure, the flow of blood and is also a component of cardiac function. When blood vessels constrict (vasoconstriction) this leads to an increase in SVR.

Detailed explanation-3: -Arterioles, small blood vessels that carry blood away from your heart, are connectors between your arteries and capillaries. They control your blood pressure and blood flow throughout your body, using their muscles to change their diameter. They also link to capillaries to exchange oxygen, nutrients and waste.
