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. they have such thin walls that substances can easily diffuse through them.
Capillaries are the smallest blood vessels in the body and are thin enough to allow for the exchange of materials (such as nutrients, oxygen, and waste products) between blood and surrounding tissues. Their thin walls facilitate this exchange by allowing substances to pass through easily.

capillaries
Capillaries are the tiny blood vessels where exchange of nutrients, gases, and waste products occurs between the blood and body tissues through the process of diffusion. They have thin walls that allow for efficient exchange of substances.
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.
Capillaries are small thin-walled blood vessels that allow for the exchange of nutrients, oxygen, and waste products between the bloodstream and surrounding tissues.
