HUMAN NUTRITION

Detailed explanation-1: -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-2: -As food is digested, blood flows through the capillaries in the intestines. These tubes pick up nutrients. These include glucose (sugar), vitamins, and minerals. These nutrients are sent to the body tissues by the blood.

Detailed explanation-3: -The capillaries have very thin walls, and through them, nutrients and oxygen are delivered to the cells. Waste products are brought into the capillaries. Capillaries then lead into small veins. Small veins lead to larger and larger veins as the blood approaches the heart.

Detailed explanation-4: -Capillaries are tiny, extremely thin-walled vessels that act as a bridge between arteries (which carry blood away from the heart) and veins (which carry blood back to the heart).

Detailed explanation-5: -The thin walls of the capillaries allow oxygen and nutrients to pass from the blood into tissues and allow waste products to pass from tissues into the blood.
