WebThe heart is essentially two of these pumps that share a common side. They also share parts of the electrical system that triggers them to contract. The right side of the heart is the smaller of the two pumps. It pumps deoxygenated blood into pulmonary circulation. The pulmonary artery carries the blood from the right ventricle to the lungs.
WebPurpose of the Heart. The purpose of the heart is to circulate nutrients, oxygen, and other chemicals to all cells in the body and to carry waste away from the cells. Our blood is a remarkable fluid that makes all of this possible. It is the job of the heart to act as a pump to move the blood throughout the body.city lights maintenanceWebWayne Boucher Mechanical Product Engineer I currently have over 35 years of experience in mechanical design and product development, predominantly in an engineering services environment developing ...city lights milwaukeeWebCardiac electromechanical coupling.
