Answer 1

Answer:

Arteries and Veins are two different types of blood vessels in the circulatory system and are mainly involved in circulating blood throughout the body. However, the two blood vessels are quite different from each other in terms of function.

One of the major differences between arteries and veins is that the arteries carry oxygenated blood to all body parts, whereas veins carry the deoxygenated blood to the heart.

Differences Between Arteries and Veins

Following are the major differences between arteries and veins:

ARTERIES VEINS

Functions

Involved in carrying pure, oxygenated blood and nutrient-rich blood. Involved in carrying impure, deoxygenated blood

Walls

Consists of three distinct layers, which are rigid, thicker and highly muscular. Consists of three distinct layers, which are thin and collapsible.

Position

Located deep within the body. Peripherally located closer to the skin.

Colour

Red in colour. Blue in colour.

Transports

Carry blood away from the heart to various parts of the body. Carry blood towards the heart from the various parts of the body.

Rate of pressure

High pressure, as the blood flows by the pumping pressure of the heart. Low pressure, as the blood flows by the capillary action of the veins.

Oxygen Level

Comparatively higher oxygen level. Comparatively low oxygen level.

Carbon dioxide Level

The level of carbon dioxide is low The level of carbon dioxide is high

The direction of Blood Flow

In downward direction from the heart to the body tissues. In upward direction from the body tissues to the heart.

Lumina

Lumina is narrow. Lumina is wide.

Valves

Valves are absent Valves are present

Disorders

Arteries are at a greater risk of certain diseases like angina pectoris, atherosclerosis, etc. Veins are less susceptible to diseases such as varicose veins.

Answer 2

Answer:

FUNCTION

•Arteries are blood vessels responsible for carrying oxygen-rich blood away from the heart to the body. Veins are blood vessels that carry blood low in oxygen from the body back to the heart for deoxygenation.

WALL

•In arteries it consists of three distinct layers, which are rigid thicker and highly muscular and In veins it consists of three distinct layers which are thin and collapsible.

VALVES

•In arteries valves are absent and In veins valves are present.
