How are capillaries differ from veins and arteries?

Answer 1

Arteries carry blood away from the heart to body tissues. Capillaries are present near almost every body cell, and they are known as exchange vessels because they permit the exchange of nutrients and wastes between the body's cells and the blood. Veins are the blood vessesl that convey blood from the tissues back to the heart.

Answer 2

1. Arteries have a thicker wall than veins.

2. Arteries have a narrower lumen than veins.

3. Veins have valves whereas arteries don't.

Importantly

An artery carries blood away from the heart, while veins transport blood to the heart.

Answer 3

Aorta and other arteries carry oxygenated blood AWAY from the heart to different parts of the body except for pulmonary artery, which is the only artery that carries unoxygenated blood. Veins, on the other hand, carry unoxygenated blood from different body parts TO the heart except for pulmonary vein.

Answer 4

Arteries carry blood from the heart. They are mainly oxygen rich (not always!)

Veins carry blood to the heart. They are mainly oxygen poor (not always!)

Arteries are thicker because they have to deal with higher blood pressures

Veins are thinner, lower pressures.

Capillaries are vessels made of epithelial tissues. They are thin to allow gas exchange.

Answer 5

Capillaries differ from veins and arteries in that they are smaller in diameter.
