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.
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!

Leukocytes
A leukocyte. White blood cell called a macrophage.
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
Capillary. The thin walls allow diffusion of materials to pass from the blood flow into the nephron.
Diffusion of oxygen and carbon dioxide takes place primarily in the capillaries, which are the smallest blood vessels in the body. Capillaries have thin walls that allow for the exchange of these gases between the bloodstream and the surrounding tissues.

Yes
Capillaries. It is only one cell thick (adaptation for diffusion)
The lack of nutrients inside a cell compared to the blood vessel creates a concentration gradient between the blood vessel and the cell. Due to the lower concentration in the cell, the nutrients diffuse through the blood vessel wall and into the cell.
Capillaries are the tiny, thin-walled blood vessels that are the site of the exchange of useful products and waste products. They allow diffusion of these materials across their thin walls.
Blood capillaries are the thinnest, their walls only a single layer thick in order to reduce the diffusion distance for substances between the blood and tissues.
An artery is a vessel with a thick medial layer, consisting of smooth muscle to allow for constriction or dilation in order to control blood flow through the vessel.
the answer can be veins or ateries or venules or capillaries... sorry i really do not know the answer... hehehe... :)
Dilation of a blood vessel is the term for physiologic widening of the vessel. Abnormal widening of the blood vessel through a weakening of the wall is known as aneurysm.Dilation of a blood vessel means widening of the vessel.
