What are the THREE MAIN TYPES OF VESSELS in the CIRCULATORY SYSTEM? wHAT ARE THEIR STRUCTURES AND FUNCTIONS?

Answer 1

I'm not sure exactly what you are asking. There are arteries, veins (Blood vessels) and lymphatic vessels.
1) Arteries carry oxygen rich blood from the heart to the body. They are more muscular in structure than veins.
2) Veins carry oxygen depleted blood from the body back to the heart. Veins have valves that help pump the blood back to the heart.
3) Lymphatic veins carry lymph from the body back into the blood via the thoracic duct

Answer 2

Of the vessels, the AERTERIES carry blood away from the heart; the **main arterial vessel, the aorta,** branches into smaller arteries, which in turn branch repeatedly into still smaller vessels and reach all parts of the body. Within the body tissues, the vessels are microscopic capillaries through which gas and nutrient exchange occurs (see respiration). Blood leaving the tissue capillaries enters converging vessels, the VEINS, to return to the heart and lungs. The human heart is a four-chambered organ with a dividing wall, or septum, that separates it into a right heart for pumping blood from the returning veins into the lungs and a left heart for pumping blood from the lungs to the body via the aorta.

Answer 3

Arteries carry blood away from the heart. they are responsible for delivering oxygen rich blood to the cells of the brain and body. when you feel your pulse you feel it in a vein.

Veins carry deoxygenated blod back tot heart. Blood tests are usually taken fromthe veins. They are the blue looking vessels you can see on your forearms.

capillaries are the smallest vessels and are a fine network of vessels which transport to and from the larger vessels to the cells of the body.

Answer 4

Everyone is generally correct about the functioning of arteries, veins , and capillaries. what everyone is forgetting is that veins do not always carry deoxygenated blood. In the systemic system they do. but with the pulmonary arteries, they carry deoxygenated blood to the lungs, then the pulmonary veins carry oxygenated blood back to the heart to be pumped out to the body.

Answer 5

Therer are only two main types of vessels - arteries and veins. Then there are arterioles, venules and capillaries. Your other two questions require more lengthy explanations. Run a search for this and get the answers for yourself.

Answer 6

3 types are Arteries formed of outer wall and inner Intima
Viens and are formed of outer Wall and Inner intima
Capillary network and they are very small vessels

Answer 7

They are arteries, veins and capillaries. You'll have to do the rest of your homework yourself.
