Question

Which blood vessels carry blood from heart to body parts?

Answer 1

A blood tube, a vessel in which blood circulates in the human or animal body. Arteries are called arteries that bring blood away from the heart, and their very tiny branches are arterioles. Very small branches are called venules, which gather the blood from the different organs and parts, and they join to form veins that return the blood to the heart.

Complete answer:
There are two kinds of blood vessels: arteries and veins.
Arteries - The blood vessels that deliver oxygen-rich blood from the heart to the body's tissues are the arteries. Every artery has three layers and is a muscular tube lined by smooth tissue.
The intima, lined by a smooth tissue called endothelium, the inner layer.
The media, a layer of muscle that enables the high pressure from the heart to be managed by arteries.
Adventitia, connective tissue that anchors arteries to neighbouring tissues.
The largest artery is the aorta, the primary pipeline of high pressure linked to the left ventricle of the heart. The aorta branches into a network of smaller arteries in the body that stretch. The tinier branches of the arteries are called arterioles and capillaries. Under low pressure, the pulmonary arteries bring oxygen-poor blood from the heart to the lungs , making these arteries special.
Veins - Veins are a type of blood vessel that carries your organs back to your heart with deoxygenated blood. These are distinct from your arteries , which carry oxygenated blood to the rest of your body from your heart. Inside tiny blood vessels called capillaries, deoxygenated blood which flows into your veins is collected. Capillaries are the body's smallest blood vessels. Oxygen passes to your tissues through the walls of your capillaries.

Note: As the pressure and flow rate are much smaller, the veins are more thinly walled. Furthermore, in order to avoid the backflow of blood, veins are structurally distinct from arteries in that the veins have valves. Contraction of the skeletal muscle helps with the flow of blood back to the heart because veins have to function against gravity to bring blood back to the heart.
