PATHOLOGY

Detailed explanation-1: -When the ventricle is full, the mitral valve shuts. This prevents blood from flowing backward into the atrium while the ventricle contracts. As the ventricle contracts, blood leaves the heart through the aortic valve, into the aorta and to the body.

Detailed explanation-2: -As the heart beats, it pumps blood through a system of blood vessels, called the circulatory system. The vessels are elastic, muscular tubes that carry blood to every part of the body.

Detailed explanation-3: -When the heart contracts, it is forcing blood through the arteries and veins of the body causing that blood to move forward away from the heart in an artery and closer to the heart in a vein. When the heart relaxes there is a temporary slowing and stopping of blood movement until the heart contracts again.
