Cardiovascular system consists of the heart, blood vessels and the blood inside them. It’s responsible for transporting oxygen, nutrition and waste products throughout the body. The heart is the circulatory pump that transports blood to the entire body. Cardiovascular system has two circulations: systemic and the pulmonary circulations.
Pulmonary circulation is the flow of blood between the heart and lungs. Pulmonary circulation starts when the deoxygenated blood enters through superior and the inferior vena cava to the right atrium. The blood passes though Tricuspid valve to the right ventricle. The right ventricle pumps blood into the pulmonary artery. Pulmonary track splits into right and left pulmonary arteries that go to each lung and blood gets oxygenated. The oxygenated blood comes back through pulmonary veins to the left atrium. Systemic circulation starts when the blood enters the left atrium. Systemic circulation is the blood flow between the heart and the rest of the body. The left atrium pumps the blood through mitral valve into the left ventricle. Then the blood passes the aortic valve and enters aorta. Aorta is the largest blood vessel in the body. Aorta branches into major arteries to supply the upper part of the body and then it branches into arteries and supplies the lower part of the body. The arteries branch into smaller arteries, arterioles, and capillaries. Oxygen diffuses in the capillaries and deoxygenated blood
