Question

define veins of human body​

Answer 1

Answer:

Veins are a type of blood vessel that return deoxygenated blood from your organs back to your heart. These are different from your arteries, which deliver oxygenated blood from your heart to the rest of your body

Answer 2

• Veins are blood vessels that carry deoxygenated blood back to your heart from your organs.
• These are not to be confused with your arteries, which transport oxygenated blood from your heart to the rest of your body.

• Capillaries gather the deoxygenated blood that passes into your veins.
• The tiniest blood veins in the body are called capillaries. Your capillaries provide oxygen to your tissues through their walls.
• Before entering your veins, carbon dioxide might enter your capillaries from the tissue.

• The venous system is the collection of veins that return deoxygenated blood to the heart.
