There are 3 types of blood vessels: Arteries, Veins, and Capillaries. Arteries carry oxygenated blood to all the cells in the body. Veins carry deoxygenated blood back to the heart where it is pumped into the lungs. There is releases CO2 gas and picks up O2 and is pumped back into the heart where Arteries take it back to the rest of the body again. Capillaries are the smallest blood vessels connecting veins and arteries.
What else can I help you with?
Differences between vasodilation and vasoconstriction?
Vasodilation is relaxation of blood vessels leading to increase in lumen size. Vasoconstriction is contraction of blood vessels leading to decrease in lumen size.
What are the differences between arteries and veins and why are these differences necessary?
Arteries carry blood from the heart to other parts of the body. Veins are much smaller vessels that are used to bring the blood back to the heart.
Supplies blood to the lungs?
the pulmonary ateries
What do ateries carry?
Blood coming from the heart.
Describe one similarity and one differences between the muscle tissue and the blood vessels you viewed with the microscope?
Muscle tissue and blood vessels both use fibroblasts, a precursor for the smooth muscle cells that stabilize the blood vessels. One difference is that the muscle tissue requires oxygenated blood in order to function.
What is a blood clot in the ateries leading to the brain?
A blood clot in an artery is an aneurysm.
Why is the blood in your ateries is under high pressure?
Cos is fit
What is a explanation for the differences in size and thickness of the different vessels?
Arteries are thicker and have more smooth muscle to withstand high pressure and maintain blood flow. Veins are thinner and contain valves to prevent backflow of blood. Capillaries are tiny and thin-walled to facilitate gas exchange between blood and tissues.
What is the relationship between heart and blood vessels?
The heart pushes blood through all the blood vessels in the body.
Star-shaped neuroglial cell between the neurons and blood vessels?
Astrocytes are star-shaped neuroglia that form the blood brain barrier between blood vessels and neurons.
The vessel that carries blood between arterioles and small vessels called venules?
The vessel that carries blood between arterioles and small vessels is called capillaries. Capillaries are the smallest blood vessels in the body where the exchange of nutrients, oxygen, and waste products occurs between the blood and tissues.
What is the relationship between thrombosis and atherosclerosis?
The only similarity between these two conditions is that they effect the blood vessels. Thrombosis is the formation of a blood clot and atherosclerosis is hardening of the arteries or blood vessels.
