Detailed explanation-1: -Arterioles connect with even smaller blood vessels called capillaries. Through the thin walls of the capillaries, oxygen and nutrients pass from blood into tissues, and waste products pass from tissues into blood. From the capillaries, blood passes into venules, then into veins to return to the heart.
Detailed explanation-2: -Answer and Explanation: Small-diameter blood vessels, such as arterioles, capillaries, and venules are part of b) Microcirculation. Microcirculation is the flow of blood through the smaller blood vessels of the cardiovascular system, including arterioles, capillaries, and venules.
Detailed explanation-3: -An arteriole (är-’tir-ē-, ōl) is a very small blood vessel that branches off from your artery and carries blood away from your heart to your tissues and organs. Arterioles are small arteries that link up to capillaries, which are smaller yet.
Detailed explanation-4: -A capillary bed can consist of two types of vessels: true capillaries, which branch mainly from arterioles and provide exchange between cells and the circulation, and vascular shunts, short vessels that directly connect arterioles and venules at opposite ends of the bed, allowing for bypass.
