Type your answer here... to supply the nutrients, oxygen and carry the impurities
You question is incomplete. What about blood vessels do you need to know?
Blood vessels are elastic in order to maintain the circulatory system. The vessels need to be able to stretch based on the force of the blood that is pumped through them. There are also receptors on blood vessels that control the diameter in order to shift blood to other parts of the body.
Capillaries, as they are the smallest blood vessels in the body, thus the need to "squeeze"
Every living tissue requires blood for it's survival, so does blood vessels, great vessels even have small vessels to supply themselves and they are called as "Vasa vasorum"
The frog's skin has many small blood vessels so that oxygen can go through the thin skin, through the fine blood vessels, and into the blood stream, allowing for the frog to breathe more easily.
All organs have blood vessels as they all need a supply of blood to be viable
because it can flow also blood in these blood vessels or the stay there if the cells need oxygen
In a closed circulatory system, the circulatory fluid remains within blood vessels at all points in the circulatory system. In an open circulatory system, the circulating fluid enters a sinus at least at one point in the circulating system and thus comes in direct contact with the tissues.
the stem VES in vessel means to carry. therefore blood vessels carry blood to where they need to go
No. You need to have blood circulating around you body
There are three major types of blood vessels in the body, the arteries, capillaries and veins. The vessels that carry blood towards the heart are the veins.
Because you need to do so to survive. Without blood circulating through the lungs, it would not be able to distribute oxygen to areas like muscle groups or the brain, and the body would quickly die.
