Question

Write four points of difference between arteries and veins.

Answer 1

Hint:Heart is the four chambered muscular organ which pumps the blood to all parts of the body by the blood vessels. It is located slightly left in the chest region in the middle of the lungs. The blood vessel may be arteries, veins and blood capillaries.

Complete answer:
Blood vessels are the tubes in which the blood is transported to and from all the organs and parts of the body.

Arteries	Veins
These are the blood vessels that carry oxygenated blood to all the parts of the body.	This blood vessels carry deoxygenated blood from all the parts of the body to the heart.
Arteries are classified into elastic artery, muscular artery and arterioles.	These are classified into deep veins, superficial veins, pulmonary veins and systemic veins.
They look red.	They look blue.
They are located deep in the body.	They are located near or beneath the surface of the skin of the body.
They have high oxygen level and low carbon dioxide level.	They have low oxygen level and high carbon dioxide level.
Arteries carry low volume of the blood.	When compared to the arteries, they carry high volume of blood.
These possess thick outer membranes	They are thinner when compared to arteries.
The blood moves fast and has no valves except the semilunar valve.	The blood moves in a sluggish way and has valves to control the blood in one direction.

Note:All arteries transport oxygenated blood except the case of pulmonary arteries which transport deoxygenated blood from the heart to the lungs for the purpose of oxygenation. Similarly, pulmonary veins alone carry oxygenated blood from the lungs to the heart, every other veins carry deoxygenated blood.
