What are blood vessels and their functions?

Answer 1

The point of blood vessels is to carry blood throughout the body. Arteries and veins are the largest of the blood vessels. Arteries move blood, which contains oxygen and nutrients to muscles and organs and veins carry the blood back to the heart. The point of blood vessels is to carry blood throughout the body.

Answer 2

Function of the Blood Vessels:

They carry blood cells(both oxygenated and carbonated ) and other platelets,salts,nutrients,waste material,bio chemicals to and from every cell,tissue,organ in the human body in various circulatory systems.

Answer 3

CIRCULATORY AND RESPIRATON

Arteries are muscular blood vessels that carry oxygenated blood away from the heart. Arteries carry oxygen-rich blood at high pressure, so they are tough on the outside and smooth on the inside. The arteries have three layers and the smoothness of the inner layer enables blood to flow easily with no obstacles.

Veins are blood vessel channels that carry waste-rich blood back to the lungs and heart. Veins carry blood at a lower pressure than the arteries, so they are not as tough as the arteries. They have three layers, which are thinner and contain less tissue than those in the arteries. The veins have valves inside them, which help ensure the blood flows in one direction through the veins and that the blood flows against the force of gravity.

Capillaries are very thin, fragile blood vessels that receive oxygen-rich blood from arteries, exchange oxygen and carbon dioxide and then deliver the waste-rich blood to the veins. Capillaries are only one epithelial cell thick and blood can only flow through them in a single file. The red blood cells inside the capillary release their oxygen, which passes through the wall and into the surrounding tissue. The tissue releases its waste products, e.g. carbon dioxide, which pass through the wall and into the red blood cells. The exchange occurs and the waste blood is carried back to the heart and lungs through the veins.

Answer 4

Types:

1- Arteries
2- Veins
3- Capillaries

Arteries bring oxygen-rich blood from the heart to the rest of the body, veins bring oxygen-poor blood from the rest of the body to the heart, and capillaries connect arteries to veins.

Answer 5

the parts of the blood vessels are veins,arteries and capillaries

arteries-are blood vessels that carry blood away from the heart.

veins-carry blood back to the heart

capillaries-are the tiny blood vessels that connects the arteries to the veins.

Answer 6

There are three major types of blood vessels: arteries, which carry oxygen and nutrients to the body. Capillaries which are very small and where O2, CO2, nutrients and wastes are exchanged. Last there are veins which carry blood back to the heart.

Answer 7

TO TRANSPORT BLOOD THROUGHOUT THE BODY AND MAIN ORGANS AND GET IT SAFELY BACK TO THE HEART.

Answer 8

for blood clotting
