The left ventricle has to pump blood through out the entire body. The right has to pump blood to the lungs which are really 'next door'.
Yes, it does. So that you can get oxygenated blood throughout your body, the right side pumps de-oxygenated blood not to the whole body, but just into to lungs to pick up the oxygen it needs, to return to the heart and be pumped to the rest of the body.
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.
Well think of the heart and blood vessles as a race track. It start at the heart goes all they way around then back to the start so the heart pumps blood to the heart, but also ateries have a layer of smooth muscle that automatically contracts to help the movement of blood.
Let me think... Arteries!!!!The main artery that begins with 'a' is the aorta. It is the artery that comes out of the right ventricle and provides the whole body with oxygenated blood.
The right ventricle pumps oxygen poor blood to the heart through the pumonary artery. (Correction- the right ventricle pumps oxygen-poor blood FROM the heart TO the lungs, not to the heart, through the right and left pulmonary arteries. The only thing that could be considered to pump blood to the heart is the "muscular pump" which is the skeletal muscle which, when it contracts, helps squeeze blood back towards the heart for venous return from the lower systemic veins.)
The right ventricle has thinner muscle, as it only needs to generate enough pressure to pump blood to the lungs (which are right next to the heart). The Left ventricle will have thicker walls because it needs to generate much more pressure to pump blood around the body.
Well, the ventricles are at the bottom. So, the right ventricle and the left ventricle, I would think.
Because God made it that way

Left Ventricle: Very very thick wall, has to pump blood at very high pressure to the whole body.Right Ventricle: Thickish wall, has to pump blood at high pressure to the lungs.Right atrium/left atrium: Thin walls, only has to pump blood to ventricles.Remember the heart chamber wall is made of muscle so think about it like the further the distance the blood needs to travel the thicker the muscle needed.The walls of the ventricles are thicker because they need to work more to push blood through them to either the lungs or systemically whereas the atria only need to move the blood into the ventricles.
I don't think you have grasped the concept... Blood is pumped thru the left ventricle to the tissues, from the tissues to the veins and into the right atrium. The right atrium pumps the blood to the right ventricle, your right ventricle pushes the blood into the pulmonary arteries, this leads to the pulmonary capillaries (in which oxygenation takes place), from there to the pulmonary veins to the left atrium, then the left ventricle....
The right Ventricle I think
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.

I believe they are the right ventricle and left atrium. There are 4 chambers and I think these are the 2 lower chambers.
Muscle cells are also known as muscle fibres. A muscle fibre is made up of myofibrils. The myofibrils are made of many myofilaments. When myofilaments are stimulated by a nerve impulse they slide over each other contracting or shortening the muscles.
because it pumps the blood around the body the fastest i think..
