Question

write three differences between arteries and veins​

Answer 1

Explanation:

arteries- Carry oxygenated blood

veins- Carry deoxygenated blood

arteries - Have thick walls

veins- Have thin walls

Arteries - Lacks Valve

Veins- Have valve

Answer 2

Answer:

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.

Explanation:

Function, walls, position, colour, Transport, Rate of pressure, Oxygen level, Carbon dioxide level, The direction of blood flow, lumina, Valves and disorders. in all these points first point is of arteries and second point is of Veins
