It depends on many factors, but in general, it is the thickest part of the heart.

Left ventricle
The left ventricle pumps the most blood out of the four, the blood from the left ventricle travels all over the body. The left ventricle pumps the most blood out of the four, the blood from the left ventricle travels all over the body.
The walls of the left ventricle are 3 times as thick as those of the right ventricle, and its cavity is basically circular. The right ventricle cavity is crescent shaped and wraps around the left ventricle, the way a hand would loosely grasp a clenched fist.
It comes from the left ventricle out through the aorta.
It helps the blood not seep through, and keeps the heart protected.
left ventricle
left ventricles . as it pump blood to the aorta it needs a high pressure to take blood all over the body . left ventricle is thick as it needs a high pressure to pump blood and to withstand that pressure.
The left ventricle, being responsible for pumping the blood through the systemic circulation, generates the highest pressures. For this reason, the left ventricle has the thickest muscular walls.
A left ventricle is not an artery.
The right ventricle pumps blood to the lungs where the alveoli oxygenate the blood. Then the blood comes back through the pulmonary veins, and into the left atrium, through the valve to the ventricle, to the pulmonary artery, and to the different parts of the body.
