Explain relationship between the diameter of vessels and the velocity of blood?
describe and explain the relationship between the diameter of vessels and the velocity of blood
What smallest blood vessels only one cell thick?
The thin walled blood vessels are called capillaries.
What blood vessels permit the exchange of nutrients and gases between blood and tissue?
Capillaries
Why are capillaries thick?
Capillaries are not thick. They are extremely thin. They are of approximately 5-20 micrometers in diameter. They are the thinnest blood vessels in the body
What Are sites of exchange between blood and tissue?
The exchange that takes place between organs and blood are **** and ********
How it can be that peripheral resistance is least in the capillaries when a capillary has the smallest diameter of any blood vessels?
Becuase the resistance is spread across thousands of capillaries.
What is the smallest blood vessel in the body?
Actually the smallest blood vessels are capillaries. These blood vessels are only about 1 cell thick and is where the gas and nutrient exchanges occur. It is also the cross-bridge between vein and arteries.
What are the thin walled blood vessels that allow the exchange of gases and nutrients between the blood and cells?
Capillaries - The endometrium (epithelial lining/wall) of the capillaries is only one cell thick optimizing diffusion/osmosis between it and the tissue cells of the body
Where does blood and fluid exchange occur?
The blood enters the capillaries in single file ( capillaries have very small diameter so blood flow through them as in single line) there by diffusion the food passes towards the cell and waste from the blood enter the blood stream
What are the small vessels where blood exchanges various materials with cells?
The human circulatory system consists of arteries, veins, and capillaries. The capillaries are the thin-walled vessels that connect arteries and veins and allow for the exchange of materials between blood and tissue fluid.
Exchange of nutrients and gases between the blood and tissue cells?
capillaries is where the exchange of materials occur such as; gases,nutrients, hormones, and so on.between the blood and the interstitial fluid.
Which blood vessels allow blood to flow between the arteries and veins?
Capillaries.
