Respiration. The main job of blood is to perform external and internal respiration, in the lungs and the tissues. This main job is called gas exchange.
Capillary: A tiny blood vessel where substances are exchanged between the blood and the body cells.
Capillaries have very thin walls to allow for efficient exchange of materials between the blood and body cells. This thinness enables the transfer of gases, nutrients, and waste products through a process called diffusion. The close proximity of blood to body cells in capillaries maximizes the effectiveness of this exchange.
Exchange of materials between the blood and body cells occurs through the process of diffusion. Nutrients, waste products, gases (such as oxygen and carbon dioxide), and other molecules move across cell membranes to maintain homeostasis within the body. This exchange is essential for delivering nutrients to cells and removing waste products from the body.
The structure of capillaries, with their thin walls and small diameter, allows for efficient exchange of materials between blood and cells in the body. The close proximity of capillary walls to surrounding tissues allows nutrients, gases, and waste products to easily pass through by diffusion. This structure ensures that vital substances like oxygen and nutrients can be delivered to cells while waste products can be removed efficiently.
Metabolites exchange by diffusion with tissue cells at the capillaries in the circulatory system. Capillaries are the smallest blood vessels where the exchange of nutrients, oxygen, and waste products occurs between the blood and the surrounding tissue cells.

Capillary: A tiny blood vessel where substances are exchanged between the blood and the body cells.
Materials are exchanged between the blood in the capillaries and the blood cells primarily through the process of diffusion. Oxygen and nutrients pass from the capillaries into the blood cells, while carbon dioxide and metabolic waste move from the blood cells into the capillaries. This exchange occurs across the thin walls of the capillaries, which are permeable to these substances, allowing for efficient transfer due to concentration gradients. Additionally, facilitated diffusion and active transport mechanisms can assist in this exchange for specific substances.
Diffusion
The human circulatory system consists of arteries, veins, and capillaries. The capillaries are the thin-walled vessels that connect arteries and veins and allow for the exchange of materials between blood and tissue fluid.
Materials are exchanged between cells and the blood mainly at the capillaries. Capillaries are tiny blood vessels with thin walls that allow for the exchange of gases, nutrients, and waste products between the blood and surrounding tissues. This exchange process occurs through the process of diffusion.
Those tiny and beautiful blood vessels are called as capillaries. You have millions of them in your body. The nutrition and oxygen is given out, at the proximal end. The metabolic wastes and carbon bi oxide in taken in, at the distal end.

Capillaries. Since they are only once endothelial cell thick, they can exchange gas, nutrients, and waste across their membrane. Capillaries in the brain have endothelial cells close together to onyl allow a slecetive exchange of materials, while capillaries in the kidney or liver have gaps between the endothelial cells to allow the exchange of a lot of materials.
