Explain why ventricle have thick muscular walls than the atrium?

the ventricle wall is thicker as it needs to pump blood from the heart to other parts of the body (either the lungs, or other parts of the body, depending which side of the heart is concerned). its extra thickness is due to more cardiac muscle, giving a stronger force of contraction to allow the blood to pumped further, under higher pressure. little muscle is needed to force blood from the atria into the ventricles, so the atrial walls are relatively thin.

in a human heart, the right-hand side of the heart is smaller than the left as less muscle is needed for the pulmonary cycle (blood being pumped to the lungs from the right ventricle) as the blood does not need to travel as far and under such high pressure as it does when pumped all around the body from the left ventricle

because in ventricle blood comes with pressure as compared to the atrium

veins have thick walls becoz they recive blood from the heart at high preasure and to with stand that preasure they have thick  walls

  • -6

arteries are having comparitively thick walls than veins because in arteries blood flows in a greater force else in veins it is very slowly and without any force

 Venctricles are pumping chambers of the heart whereas the artia recieve blood. Since ventricles have to pump blood to varoius parts of the body, they have thicker walls than atria do.

above answer is correct

Ventricles have to pump blood into various organs and so they have thicker muscular walls than atria.

The walls of ventricles are thick and muscular as compared to the walls of atria as the required to pump blood to various organs. Right ventricle sends deoxygenated blood to lungs through pulmonary artery whereas left ventricle sends oxygenated blood to all parts of the body through arota

The blood is under high pressure because the blood which is pumped out of the body is under high pressure

Ventrucles have thick muscular walls than atrium because the blood from various parts of body comes directly to ventricles so it creates a high blood pressure so in order to compensate the B.P. ventricles have muscular walls.
 
The Heart is divided into four chambers namely two upper Atria and two lower Ventricle.
The atria have comparatively thinner walls than the ventricles because atria only receive blood from the upper parts of the body,i.e., head, etc. and the ventricles have to pump the blood to the farthermost parts of the body, for example, the toes to up to head,i.e., against gravity.
 
The pressure in the ventricles is low than the pressure in the atria as the ventricles should carry the deoxygenated blood to the lungs the ventricles needed to push it very hardly so in order to carry the blood this ventricles are having thick walls than atria
 
ince ventricles have to pump blood into various organs, they have thicker muscular walls than atria do.
