NEET PG DENTAL EXAM

Detailed explanation-1: -Capillaries are small, thin blood vessels that connect the arteries and the veins. Their thin walls allow oxygen, nutrients, carbon dioxide and waste products to pass to and from the tissue cells.

Detailed explanation-2: -These bring oxygen and other nutrients to the cells of the body’s tissues and organs. The smallest tubes are called capillaries. As blood moves through the capillaries, the oxygen and other nutrients move out into the cells. Then waste matter from the cells goes into the capillaries.

Detailed explanation-3: -Capillaries: These tiny blood vessels have thin walls. Oxygen and nutrients from the blood can move through the walls and get into organs and tissues. The capillaries also take waste products away from your tissues. Capillaries are where oxygen and nutrients are exchanged for carbon dioxide and waste.

Detailed explanation-4: -During gas exchange oxygen moves from the lungs to the bloodstream. At the same time carbon dioxide passes from the blood to the lungs. This happens in the lungs between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the alveoli.
