Question

what are the major differences between arteries and veins

Answer 1

$\large{\bold{\underline{Arteries :}}}$

• Arteries are thick walled vessels which carry oxygenated blood away from heart.

• The only exception to this is the pulmonary artery which carries deoxygenated blood.

• Arteries have strong muscular wall as they contain blood under high pressure.

• It is further branch into smaller vessels known as the arterioles.

$\large{\bold{\underline{Veins : }}}$

• Veins carry deoxygenated blood to the heart.

• Only pulmonary veins carry oxygenated blood to the heart.

• Veins have valves in them which allow the blood flow in a single direction.

• Veins have comparatively thin walls than arteries as they contain blood under low pressure.

• Veins branch into smaller vessels known as the venules.
