capillaries
Capillaries via osmosis
capillaries have walls thin enough to allow the exchange of materials between cells and the blood. Their extensive branching provides a sufficient surface area to pick up and deliver substances to all cells in the body.
Tiny blood vessels that allow substances to pass between the blood and body tissues are called
cappillaries
No, capillaries are what allows substances to go from the walls of the small intestine into your cells. Veins are what carry the blood (with cells inside) to the heart to be oxygenated.
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
Capillaries. they have such thin walls that substances can easily diffuse through them.
capillaries
Capillaries.
The walls which allow substances to pass backwards and forwards between the blood and the cells are called capillaries. They are microscopic blood vessels have walls which are 'leaky' which allows substances to pass backwards and forwards. Narrow arteries and veins are connected by capillaries.
Perforating (Volkmann's ) canals.
Basically they have a thin cell membrane to allow the substances to travel from the capillary to the surrounding cells easier.
