Match the characteristics to the blood vessels.
Darina [25.2K]

Answer:

Arteries transport blood away to the different parts of the body from the heart. Arteries are the largest blood vessels in the whole body with elastic walls.  

Hence arteries match with carries blood away from the heart and largest blood vessel in diameter

Capillaries take blood from various parts of the body. It exchanges nutrients, oxygen, and waste with tissues or cells. These are the smallest blood vessels.

Hence capillary matches with exchanges nutrients with tissues and single walled.  

Veins transport the blood to the heart from the body. These vessels have a thin endothelial layer.  

Hence Vein matches with carries blood to the heart and has a thin endothelial layer.
