A. Let’s start by discussing the structure of our blood vessels. Let’s each take a characteristic of (1) arteries, (2) veins, or (3) capillaries. Build upon what your classmates say to enable us to have a fuller understanding of these vessels that are essential for our existence.
The arteries’ primary function is to transport oxygenated blood out from the heart. In order to maintain the blood flowing through the heart, the arteries have thicker walls and a muscular layer (Saladin, 2021).
The veins’ characteristic function is to transport anemic blood to the heart. The veins won’t have the same layers of muscle that the arteries have. The valves are what the veins rely on to keep the blood flowing. Venules are the tiniest veins in the body, which develop into larger veins as they go closer to the heart. Veins have thin walls and thin muscular tissue layers (WebMD, 2022).
All tissues contain capillaries, which have thin walls and are present throughout the body. Since the capillaries lack muscular tissue and valves, they may transport both oxygenated and deoxygenated blood. All around the body, capillaries—narrow blood vessels—can be seen.
