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.
oxygen, carbon di oxide, glucose, fatty acids, glycerol, minerals, ions, creatinine, other wastes, hormones, amino acids. . . Etc
The blood brings oxygen and nutrients to the cells of the body and takes carbon dioxide and waste from the cells of the body.
Capillaries!
Diffusion!

EPIC
Capillary: A tiny blood vessel where substances are exchanged between the blood and the body cells.
capillaries is where the exchange of materials occur such as; gases,nutrients, hormones, and so on.between the blood and the interstitial fluid.
There are many substances they exchange, but the main ones are oxygen from the blood to the cells and CO2 from the cells to the blood.
Capillaries have cell walls that are onlt one cell thich to allow nutrients to pass through and into the body cells and back again. I hope this helps :-)
No. The exchange of gases between the blood and tissue cells is called internal respiration. External respiration refers to the exchange of gases between the blood and the air inside of the alveoli of the lungs.

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.

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.

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.
There are many substances they exchange, but the main ones are oxygen from the blood to the cells and CO2 from the cells to the blood.
It helps in exchange of materials and gases between the blood and other surrounding cells easily.
