5479637053	Aorta	A large arterial trunk that arises from the base of the left ventricle and channels blood from the heart into other arteries throughout the body	24
5479637054	Aortic valve	The semilunar valve between the left ventricle and the arota that prevents blood from flowing back into the left ventricle	25
5479637055	Artrioventricular (AV) valves	The two valves (tricuspid and mitral) situated between the atria and the ventricles	26

5479637057	Diastole	The period of relaxation in the heart when the chambers are filling with blood	28
5479637058	Endocardium	The innermost layer in the heart , which lines the interior of the heart chamber and covers the valves of the heart	29
