Human Heart Modifies Its Activity According to the Circumstances

In order to circulate blood through the body, the heart is always in motion. The heart is always using the same amount of strength to send blood to the body. The human heart is divided into 4 chambers: the right and left atria (on the top) and the right and left ventricles (on the bottom). When blood flows into the heart, it first enters the right atrium before passing through the right ventricle, and then the heart utilizes blood vessels called pulmonary arteries to pump blood to the lungs. Blood leaving the lungs travels through blood vessels called pulmonary veins to return to the heart, flowing through the left atrium, left ventricle, and then the entire body. The wall between the ventricles sending out blood is thick, while the wall between the atria receiving blood is thin. The valves at the entrance/exit of each chamber regulate the flow of blood. As blood gathers in the atria, pressure increases on the valves until they open to let blood flow into the ventricles. The valves then close against the ventricles so that blood will not flow backwards by accident. These valves allow blood to always flow in the same direction. Also, the heart increases its activity exactly in proportion to the amount of blood that needs to circulate during times of exercise. The heart modifies its activity according to the circumstances and is able to control the proper flow of blood under all circumstances.

Heart functioning can be used to develop powerful pumps capable of preventing backward flow while regulating pressure. It can also be used to develop pumps capable of swiftly adjusting to change and minimizing damage.
