The walls of the Ventricles are thicker than the walls of the auricle since blood is pumped to the different parts of the body from the auricle thus requiring it to be thicker to handle the pressure applied.
The auricle? This is just what is left of the primordial atrium and in adult life is just a small ear shaped (that where the name comes from) pouch on the right artium. It has almost no function other than to increase the volume of the atrium and its contraction force is roughly similar to that atrium. The atria dont have very thick walls as they do not need to pump very hard to get the blood into the ventricles. The ventricles must get the blood all around the body (left ventricle) or to the lungs (right ventricle) which require much more force and so the walls arethicker to provide the necessary strength.
The cardiovascular system can be described as three parts: the pump, the pipes, and the fluid. As the pump, the heart walls, specifically in the ventricles, are made of thick muscle, in order to generate enough force to move blood to the rest of the body. The aorta on the other hand is part of the pipe system. The do not need to generate movement, so thick walls are unnecessary. The walls of the aorta do flex and contract was blood is pumped through them, but it is in response to the heart muscle contraction, and this flexibility allows it to maintain a stable blood pressure.

The right ventricle pumps blood through the pulmonary arteries into the lungs. Because the lungs are very close to the heart, the right ventricle doesn't have to work as hard as the left ventricle so its wall is not as thick. The left ventricle pumps blood through the aorta to the rest of the body. This requires the left ventricle to pump very hard and this causes the wall of the left ventricle to become thicker.
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 they need to be stronger. The atria only pump the blood into the lower chambers, the ventricles. Whereas, they have to pump the blood either to the heart or the rest of the body.
because the left ventricle pumps blood to the rest of the body
Because both ventricles need greater pressure to pump blood. The right ventricle pumps deoxygenated blood to the lungs and the left ventricle pumps oxygenated blood to the whole body.
Ventricles have thicker valve thicker wall so that they can withstand the intense pressure by the heart.While auricles carry blood towards the heart and suffers reduced pressure so it has thinner wall
The walls of the ventricles of the heart aren't thinner than the atria, they are thicker. This is because they require more power as they pump blood around the body, while the atria only pump blood the short distance into the ventricles. More muscular walls are therefore needed to provide this power which is why they are thicker. The left ventricle is even thicker than the right ventricle as it requires a lot more power to pump blood all around the body. The right ventricle only pumps blood to the lungs.
The wall of the left ventricle is thicker because it pumps blood to the entire body. The right ventricle pumps blood to the lungs, so it does not have to be as strong as the left ventricle.The oxygenated blood that comes into the left ventricle has to be transported to all the parts of the body. For this reason, the left ventricle has thicker muscle walls that pump blood at a higher pressure than the right ventricle that pumps blood only to the lungs.
The lower two chambers of the heart are the ventricles. The left ventricle is larger, with thicker walls, than the right ventricle.
The right ventricle just receive the blood and pump it into the lungs only, but the left ventricle pump the blood to all round the body, to do the ventricle wall is more thicker, that's why the left ventricle have thicker wall..... Hope I helped you!! (Ivy Yumi Y)
The ventricle wall is thicker as it needs to pump blood from the heart to other parts of the body and so it has more pressure than the ventricle walls.
you are mistaken...the ventricular walls are thicker than the auricular walls.. The left ventricle is further thicker than the right ventricle. This is because the left ventricle has to transport blood to all the parts of the body and has to travel a long distance hence requires it to be transported at great pressure. As a result the wall is thicker. The auricles only have to pump blood into the ventricles underneath them and therefore don't require alot of pressure hence are not thick. The right ventricle however pumps the deoxygenated blood into the lungs and has to travel a relatively short distance since the lungs are close to the heart hence not alot of pressure is required either. All this explains why the Ventricular walls are generally thicker than the auricular walls.
The wall of the ventricle is thicker than the walls of the atria because the ventricle pumps blood throughout the body, and the wall of the ventricle needs to be thick snd muscular in order to do so.

Do you mean that the left ventricle's walls are thicker than the right's? It's because one side has to pump blood only to the lungs, while the other side needs to pump blood to the entire body, and needs to be stronger.
A ventricle's walls are thicker than those of the atrium because it needs to generate higher pressure. This higher pressure is needed to push blood into the circulation, while the atrium only needs to push blood into the ventricle.
The walls of the ventricles of the heart aren't thinner than the atria, they are thicker. This is because they require more power as they pump blood around the body, while the atria only pump blood the short distance into the ventricles.

The short Answer: The ventricles have thicker walls than the atrium simply because this is the part of the heart that does most of the pumping action by contracting. It has to be strong and fairly thick to cope with the pressure. (Ventricles have thicker walls than the atrium, which creates a higher blood pressure. The left ventricle has thicker walls because it needs to pump blood to the whole body. The wall of the left ventricle is 8-15 mm The right atrium's wall is approximately 2mm in thickness, due to the combined influence of the low pressure of this chamber and the ease of pumping to low pressure areas)
The thicker walls of the left ventricle allow for greater pumping force. This increased force is needed because blood in the systemic circuit must travel much farther than that in the pulmonary circuit.
The right ventricle just receive the blood and pump it into the lungs only, but the left ventricle pump the blood to all round the body, to do the ventricle wall is more thicker, that's why the left ventricle have thicker wall..... Hope I helped you!! (Ivy Yumi Y)
