The Heart. The heart itself is made up of 4 chambers, 2 atria and 2 ventricles. De-oxygenated blood returns to the right side of the heart via the venous circulation. It is pumped into the right ventricle and then to the lungs where carbon dioxide is released and oxygen is absorbed.

The heart and lungs are located in the thorax, or chest cavity. The heart pumps blood from the body to the lungs, where the blood is oxygenated.

The heart is a pump that moves blood through the body. Blood begins its journey on the right side of the heart where it is pumped into the lungs to exchange carbon dioxide waste for oxygen. It then flows back to the left side of the heart where it is pumped out to the body through the arteries.

The Heart Is a Muscle Your heart is really a muscle. It's located a little to the left of the middle of your chest, and it's about the size of your fist. There are lots of muscles all over your body — in your arms, in your legs, in your back, even in your behind. But the heart muscle is special because of what it does.

The right ventricle is the chamber within the heart that is responsible for pumping oxygen-depleted blood to the lungs.

The upper two chambers are called atria (singular: atrium) and the lower two are known as ventricles (singular: ventricle). Muscular walls, called septa or septum, divide the heart into two sides. On the right side of the heart, the right atrium and ventricle work to pump oxygen-poor blood to the lungs.

I think that, "You have a special place in my heart," means that no human being, living or dead, usurps or ever takes over that place of specialness that you always have within him: within his thinking, within his feelings, and within his actions that are for you, alone. From your question, I don't know who “he” is.
