oxygen
Both red and white blood cells pass through the capillaries.
capillaries
Yes
Capillaries are very thin blood vessels. Oxygen and nutrients and hormones can pass through the walls of the capillaries and reach the body's cells, while red blood cells remain in the capillaries.
diffusion from red blood cells in capillaries to the tissue cells
through arterioles
The round cells that move in the blood capillaries are called RED BLOOD CELLS.
Capillaries. They're so small that red blood cells are sometimes forced to travel single-file.
Arterioles.
roundish
As red blood cells travel through capillaries oxygen is released (disassociated) with hemoglobin. The oxygen then diffuses down it's concentration gradient into the tissues.
