Document Summary
Anterior view of the heart; from the front. Blood returns from the lungs through the pulmonary veins: only veins in the body that carry oxygenated blood, this blood is draining into the left atrium, going through the mitral valve into the right ventricle. Blood ejected into the aorta by passing through the aortic valve. The atria & the ventricles are separated from each other by a connective tissue skeleton (fibrous skeleton) Plane cutting through at the level of the fibrous skeleton: atria have been removed, we are looking at the ventricle, anterior: top of diagram, posterior: bottom of diagram. Fibrous skeleton is: dense irregular connective tissue, non conducting; acts as an insulator between atria & ventricles. Chamber of the ventricle; where the blood is located. Adipose tissue laid down on top of a fibrous pericardium; outermost covering of the heart.
