Explanation:
Detailed explanation-1: -The smooth muscle cell directly drives the contraction of the vascular wall and hence regulates the size of the blood vessel lumen.
Detailed explanation-2: -Vascular smooth muscle is found in arteries, arterioles, veins, and lymphatic vessels. The contractile state of VSMC establishes the diameter of these vessels and thus resistance to flow.
Detailed explanation-3: -’ That is: vascular smooth muscle contracts, blood vessels become narrower and less blood flows through them. This process is called ‘vasoconstriction. ‘
