this is a false statement blood capillaries do not exchange in diffrent part of your body
Capillary: A tiny blood vessel where substances are exchanged between the blood and the body cells.
Oxygen and nutrients are delivered from the blood to tissues, and waste products such as carbon dioxide and metabolic byproducts are removed from tissues and transferred into the blood in the exchange at capillaries.
Capillaries via osmosis
Capillaries have thin and permeable walls which allow the exchange of substances (such as nutrients, oxygen and CO2) to occur. This enables substances to dissociate throughout the entire body (as capillaries are present throughout the entire body).
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.
The circulatory system because the artery and the heart is their.
In the exchange at capillaries, substances such as oxygen, carbon dioxide, nutrients (glucose, amino acids), waste products (urea, carbon dioxide), and hormones move into and out of the blood. This exchange occurs to ensure that cells receive the necessary nutrients and get rid of waste products.

capillaries
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 are the connection between arterioles and venules. The capillaries job is to enable the exchange of oxygen, water, carbon-dioxide, chemical substances and various nutrients to between blood and the surrounding tissue.
