Nutrients are exchanged between the blood and body cell in the capillaries.
Capillary: A tiny blood vessel where substances are exchanged between the blood and the body cells.
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.
Oxygen, nutrients, waste products, hormones, and electrolytes are exchanged between the body cells and the blood plasma. This exchange occurs through the capillaries that connect the circulatory system with the cells in the tissues. Oxygen and nutrients are delivered to the cells, while waste products and carbon dioxide are removed from the cells and transported back to the excretory organs for elimination.
Reabsorption is the process by which materials are returned to the blood from the filtrate in the kidneys. This process helps to maintain the body's balance of electrolytes, nutrients, and water by reabsorbing essential substances back into the bloodstream.
Oxygen (O2) is exchanged for carbon dioxide (CO2) in the lungs. In the alveoli, tiny air sacs in the lungs, oxygen from the air is transferred into the bloodstream while carbon dioxide from the blood is released into the air to be exhaled.

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.
Oxygen is exchanged from the air in the alveoli into the blood in the capillaries, while carbon dioxide is exchanged from the blood in the capillaries into the air in the alveoli during the process of respiration.
capillaries
diffusion is when the materials go through the cell membrane between the capillaries (because capillaries are only one cell thick)
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.
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.
