Two more semilunar valves a cool way to improve sit within the exit of each from the ventricles. The pulmonary valve is located at the base on the pulmonary artery. This has 3 cusps which aren't hooked Heart operation up to any papillary muscles. When the ventricle relaxes blood flows back in to the ventricle from your artery which stream of blood fills the pocket-like valve, urgent versus the cusps which near seal the valve.
The left ventricle pumps blood to the human body with the aortic valve and to the aorta. Two tiny openings higher than the aortic valve have blood to your heart by itself, the still left main coronary artery and the right coronary artery.[seven] Heart wall
