capillaries
Capillary: A tiny blood vessel where substances are exchanged between the blood and the body cells.
Exchange among subdivisions of the extracellular fluid (ECF) occurs primarily at the capillaries, where nutrients, gases, and waste products are exchanged between the blood and interstitial fluid. This exchange is facilitated by the thin walls of capillaries and the pressure differences between the blood and surrounding tissues.

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.
yes capillaries are connected to heart because heart is a muscular organ and the exchange of materials between heart walls and blood occurs through capillaries.
The capillaries are the primary sites of exchange between blood and tissues. Capillaries are small blood vessels with thin walls that allow for the exchange of oxygen, nutrients, and waste products between the blood and the surrounding tissues. These exchanges are essential for maintaining the proper function of tissues in the body.
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.
Capillaries
This process occurs through the capillaries. Nutrients and oxygen diffuse from the blood into the tissues, while waste products and carbon dioxide diffuse from the tissues into the blood. This exchange is facilitated by the thin walls of the capillaries and the high surface area for diffusion.
