NEET PG DENTAL EXAM

Detailed explanation-1: -A capillary bed can consist of two types of vessels: true capillaries, which branch mainly from arterioles and provide exchange between cells and the circulation, and vascular shunts, short vessels that directly connect arterioles and venules at opposite ends of the bed, allowing for bypass.

Detailed explanation-2: -Capillary bed is a network of numerous capillaries formed from true capillaries and/or vascular shunts. Capillaries connect arterioles and venules and enable the exchange of water, oxygen, carbon dioxide, and many other nutrients and waste substances between the blood and surrounding tissues.

Detailed explanation-3: -Capillaries are microscopic blood vessels that connect the arterioles with the venules, and a network of capillaries is known as a capillary bed. The fluid that leaks out of the capillaries is known as interstitial fluid. It’s this leaked interstitial fluid that bathes your body cells in nutrients.

Detailed explanation-4: -The smallest of the arteries eventually branch into arterioles. They, in turn, branch into a extremely large number of the smallest diameter vessels-the capillaries (with an estimated 10 billion in the average human body).
