Yes, some can. The sort of squeeze through "cracks' in the very tiny vessels called capillaries. Injury or trauma can cause white blood cells to migrate out. This process is called diapedesis .Part of the swelling due to injury or infection is caused by diapedesis. The white cells are intensely active, because as well as destroying bacteria, they also work to form a barrier around an infection that can help prevent the rest of the body from becoming infected.
Red blood cells are too small to contain blood vessels. They are cells and they travel in blood vessels.
Red blood cells travel in a liquid called plasma found in the blood vessels.
no
Only in the tiny blood vessels that feed the cells in those tissues.
Blood cells travel to and from the pump called the heart by way of the blood vessels called the arteries and veins.
True. Epithelial tissues do not contain blood vessels, which is why they rely on diffusion from nearby blood vessels in connective tissues for their nutrient and oxygen supply.
Simple epithelial tissues have no blood vessels and line or cover structures.
The Capillaries transfers waste filled blood from the tissues into the Pulmonary circulation.capillariesTiny blood vessels that pass food and oxygen to cells and receive waste from cells.
Blood vissels carry blood cells that carry food and water for your body tissues.
Simple epithelial tissues have no blood vessels and line or cover structures.
White blood cells, red blood cells, and platelets all travel within the bloodstream to reach different parts of the body where they are needed. They are carried by the circulating blood to various tissues and organs to perform their respective functions, such as fighting infections (white blood cells), delivering oxygen (red blood cells), and aiding in blood clotting (platelets).
Red blood cells are found in a liquid tissue called plasma carried inside blood vessels.
