Pulmonary Circuit Essay

Pulmonary circuits take the blood (that has no oxygen) from the heart to the lungs. The blood travels through the veins [systemic], to the vena cava and the right atrium. From the right atrium, it travels to the right ventricle and out to the pulmonary arteries. From here the blood picks up oxygen and drops off the carbon dioxide. Systemic circuits take the oxygenated blood from the lungs to the heart. The blood travels back into the pulmonary arteries. From there the blood moves from the arteries to the left ventricle and left atrium. The blood then goes out of the aorta through the systemic veins. When it gets to the systemic capillary beds it drops off the oxygenated to the rest of the body tissues. Pulmonary and systemic circuits both use the same types of veins and arteries. The circuits go in a loop in opposite directions. When one circuit drops off the blood, the other circuit picks it up and goes back through the heart. The pulmonary circuit goes through the right part of the heart. The systemic circuit goes through the left part of the heart.

The heart is the organ that pumps the blood throughout the body. It has three chambers: the atria, the ventricles, and the septum. It also contains two main valves: the tricuspid and the bicuspid (the atrioventricular valves). It has two sections that carry the different types of blood (oxygenated and deoxygenated). The oxygen depleted blood goes through the right atrium to the right ventricle. From the right ventricle the blood goes out of the pulmonary artery to the lungs; which is referred to as the pulmonary circuits. The oxygen rich blood goes from the lungs to the left ventricle. From the left atrium, it travels to the left ventricle and out through the aorta to the different parts of the body; referred to as the systemic
