PATHOLOGY

Detailed explanation-1: -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-2: -Step by step answer:The left ventricle has the thickest walls since it is the major siphoning office of the heart. The oxygenated blood enters the left chamber, goes through the bicuspid valve and into the left ventricle. The blood leaves the left ventricle through the aortic semilunar valve and enters the aorta.

Detailed explanation-3: -Veins carry deoxygenated blood from the body back to the heart. iv. They are thin-walled as the blood that flows through veins is under low pressure. Hence, arteries are thicker than veins.
