The heart’s lower two chambers, the right and left ventricles, are the powerful pumping chambers. The ventricles propel blood into arteries, blood vessels that carry blood away from the heart. The right and left sides of the heart are separated from each other by a wall of tissue. Each ...
CONSTITUTION:At least either one of the first abutting recessed portion 15a or second abutting recessed portion 15b of the outer wall 11 of a heart-shaped cam, to which a moveable element 4 is made to abut when the element is pressed, and the moveable element 4 is formed in such a ...
arteries - vessels through which the blood passes away from the heart to the various parts of the body. The wall of an artery consists typically of an outer coat (adventa), a middle coat (media), and an inner coat intima). atherosclerosis - an extremely common form of arteriosclerosis (a...
The inner surfaces of the human heart are covered by a complex network of muscular strands that is thought to be a remnant of embryonic development1,2. The function of these trabeculae in adults and their genetic architecture are unknown. Here we performed a genome-wide association study to in...
