What blood vessel allow diffusion?

Answer 1

The capillaries allow diffusion of nutrients, waste, and oxygen through their walls, which are one cell thick. This diffusion allows transportation of nutrients and waste materials throughout the body.

Answer 2

erythrocyte
immune cells
Reticulocytes (RBC) have intravascular function (within blood vessels)
White blood cells can pass through the blood vessel walls when required.

They do this to help prevent infection when you have broken the skin.

The vessels allow them to leak through so that the white blood cells can fight any pathogens that might otherwise enter the bloodstream.

Hope this helps!
no
Leukocytes
A leukocyte. White blood cell called a macrophage.

Answer 3

CAPILLARIES.....
Capillaries.
capillaries
The capillaries. Nutrients and oxygen move from the blood through the arterial capillary walls into the body tissues, and wastes and carbon dioxide move through the venous capillary walls from the body tissues into the blood.

For an illustration of capillary structure and blood flow, refer to the related link.
These are capillaries. They are very thin so that gas and nutrients can be exchanged. They are found in beds which have many of these vessels.

I believe its the capillaries

Answer 4

Leukocytes move through blood vessel walls to enter tissues. They do this using a process called diapedesis. It is something like a thin amoeba squeezing their way through small spaces between cell walls.

Answer 5

I'd say capillaries. These vessels are only one cell thick which allows other molecules to pass through easily.

Answer 6

Capillaries are the blood vessels that allow diffusion. For instance, the capillaries surrounding the alveoli in the lungs allow diffusion of gases.

Answer 7

Capillaries.
