Explanation:

Arteries

Arteries are thick blood vessels which are capable to carry oxygenated blood to all body parts.

=>In arteries blood pressure so much high that's why they are thick.

Veins

Veins are thin blood vessels which carries de-oxygenated blood and supply to the heart.

Major difference between artery and veins

Artery =>

• They carries only oxygenated oxygen rich blood to the body parts.it is enrich with nutrients.
• Generally red in colour because it is oxygen rich and haemoglobin.
• It carries blood from heart to different body parts.
• As blood comes from the heart so it have high pressure.
• flow of movement of blood is downward.

Veins =>

• They carries de-oxygenated carbon contains blood.
• Generally greenish and bluish in colour due to impure blood particles.
• It supplies deoxygenated blood from body to the heart.
• it have low pressure than the arteries.
• Flow is upward as it is goes to heart from all body parts.
