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.

Detailed explanation-2: -Arterioles carry blood and oxygen into the smallest blood vessels, the capillaries.

Detailed explanation-3: -Oxygen, nutrients and hormones are delivered around the body in the blood and carbon dioxide and other waste products are removed.

Detailed explanation-4: -The arteries (red) carry oxygen and nutrients away from your heart, to your body’s tissues. The veins (blue) take oxygen-poor blood back to the heart.

Detailed explanation-5: -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.
