MICROANATOMY

Detailed explanation-1: -Capillaries are the blood vessels that reach out to small cells and tissue, helping in the exchange of materials like oxygen, carbon dioxide, and waste. Capillaries are semipermeable so that material can be exchanged with surrounding cells.

Detailed explanation-2: -Capillaries, the smallest and most numerous of the blood vessels, form the connection between the vessels that carry blood away from the heart (arteries) and the vessels that return blood to the heart (veins). The primary function of capillaries is the exchange of materials between the blood and tissue cells.

Detailed explanation-3: -Capillaries are tiny vessels that transport blood, nutrients and oxygen to cells in your organs and body systems.

Detailed explanation-4: -Capillaries allow exchange of substances with body tissues through their thin walls. As blood travels at high pressure in the arteries towards the capillaries, pressure filtration occurs which results in plasma passing through the capillary wall into the tissue fluid which surrounds the cell.

Detailed explanation-5: -Capillaries are the smallest blood vessels in the body that convey blood between the arterioles and venules. These microvessels are the site of exchange of any substance with the interstitial fluid surrounding them.
