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.
Tiny blood vessels that allow substances to pass between the blood and body tissues are called
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.
capillaries
Capillaries via osmosis
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 are tiny blood vessels where diffusion takes place between the blood and body tissues. Their thin walls allow for the exchange of oxygen, nutrients, and waste products between the blood and the surrounding tissues.
Capillaries are small thin-walled blood vessels that allow for the exchange of nutrients, oxygen, and waste products between the bloodstream and surrounding tissues.
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.
because they have a long tissues that the blood flows
Capillaries are the smallest blood vessels, and they allow for gas exchange in the tissues.
Tiny blood vessels are called capillaries. They have thin walls that allow for the exchange of oxygen, nutrients, and waste products between the blood and surrounding tissues.
Capillaries are the small blood vessels where oxygen is exchanged for carbon dioxide. They are located throughout the body and allow for the exchange of gases between the blood and tissues.
