Document Summary

Bag that wraps around the heart and forms part of the heart muscle. Outermost layer of cells around the heart. The heart is the size of your fist. Walls are ridget by trabeculae carneae papillary muscles project into the ventricular cavities. Pulmonary trunk leaves the right ventricle aorta leaves the left ventricle. The heart is a two sides-by-side pump. Right side pumps blood to and through pulmonary lung arteries and veins (everything but lungs) Systemic veins right atrium tricuspid valve right ventricle. Pulmonary valve pulmonary trunk pulmonary arteries lung capillaries. Pulmonary veins left atrium mitral valve left ventricle aortic valve ascending aorta systemic arteries systemic capillaries. Equal volumes of blood are pumped to the pulmonary and systemic circuits. Pulmonary circuit is a short, low-pressure circulation. Systemic circuit blood encounters much resistance in the long pathways. Anatomy of the ventricles reflect these differences. The functional blood supply to the heart muscle itself.
