Match the characteristics to the blood vessels. has a thin endothelial layer carries blood to the heart single walled largest blood vessel in diameter carries blood away from the heart exchanges nutrients with tissues artery vein capillary

Artery : carries blood away from the heart, largest blood vessel in diameter  

Vein : carries blood to the heart, has a thin endothelial layer.

capillary : exchanges nutrients with tissues, single walled.

Explanation:

Arteries are blood vessels that transport blood away from the heart to the body. They are the largest blood vessels in the body and have thick elastic walls.  

Capillaries are blood vessels that carry blood away from body and exchange waste, nutrients, and oxygen with cells or tissues. Capillaries are smallest blood vessels and their walls contain only a single layer of tissues.

Veins are blood vessels that transport the blood from the body to the heart. Veins have less connective and smooth muscle tissue that make veins' walls thinner that walls of arteries.

Artery: carries blood away from the heart, largest blood vessel in diameter

Vein: carries blood to the heart, has a thin endothelial layer

Capillary:  single walled, exchanges nutrients with tissues.

Explanation:

Arteries: They carry oxygen-rich blood away from the heart to all of the body's tissues. They branch into smaller and smaller arteries as they carry blood farther from the heart and into organs.

Capillaries: These small blood vessels connect the arteries and the veins. Their thin walls allow oxygen, nutrients, carbon dioxide, and other waste to pass to and from cells.

Veins: These are blood vessels that take blood back to the heart. They get become larger as they get closer to the heart. The superior vena cava is the large vein that brings blood from the head and arms to the heart, and the inferior vena cava brings blood from the abdomen and legs into the heart.
