MICROANATOMY

Detailed explanation-1: -The correct answer is Arteries. The blood flows in a fixed route through arteries and veins maintains a continuous flow throughout the body inside the closed tube or blood vessels. These vessels are of mainly 2 types. The walls of arteries are thick and non-collapsible, the pressure inside them is very high.

Detailed explanation-2: -Arteries have thick walls and are situated superficially in comparison to other blood vessels. Arteries are blood vessels, the network of pathways through which the oxygenated blood travels away from the heart to various cells, tissues, and organs of the human body.

Detailed explanation-3: -Blood pressure in the arteries is much higher than in the veins, in part due to receiving blood from the heart after contraction, but also due to their contractile capacity. The tunica media of arteries is thickened compared to veins, with smoother muscle fibers and elastic tissue.

Detailed explanation-4: -Walls of the arteries are thick because they have to withstand the high pressure released from the heart during the process of pumping the blood. Therefore, the thick walls of the arteries help in maintaining the blood pressure simultaneously by controlling blood flow.

Detailed explanation-5: -Since the blood pumped from the heart into the arteries flows at higher pressure than the blood in veins, hence arteries need to have thicker walls or else the high blood pressure might cause them to burst.
