Heart valves separate atria from ventricles, and ventricles from great vessels. The valves incorporate two or three leaflets (cusps) around the atrioventricular orifices and the roots of great vessels. The cusps are pushed open to allow blood flow in one direction, and then closed to seal the orifices and prevent the backflow of blood Anatomy of the heart One of the most essential and functional parts of the human body is the heart. The size of the heart could be identical to that of a closed fist and it lies beneath the sternum and between the second and the sixth intercostal space. However, the exact position of it varies to some extent in each person

The heart functions by pumping blood both to the lungs and to the systems of the body. To prevent blood from flowing backwards or regurgitating back into the heart, a system of one-way valves are present in the heart. The heart valves can be broken down into two types: atrioventricular and semilunar valves. Atrioventricular valves. The atrioventricular (AV) valves are located in the middle of the heart between the atria and ventricles and only allow blood to flow from the atria into. 6 - the heart: name the parts of the human heart. 7 - the muscles: Can you identify the muscles of the body? 8 - anatomical planes and directions: Do you know the language of anatomy? 9 - the spine: Test your knowledge of the bones of the spine. 10 - the skin: understand the functions of the integumentary syste Heart Anatomy.
