    The pulmonary valve (sometimes referred to as the pulmonic valve) is a valve of the heart that lies between the right ventricle and the pulmonary artery, and has three cusps. It is one of the four valves of the heart and one of the two semilunar valves , the other being the aortic valve .

  3. Heart valve - Wikipedia

    en.wikipedia.org/wiki/Heart_valve

    The aortic and pulmonary valves are located at the base of the aorta and the pulmonary trunk respectively. These are also called the "semilunar valves". These two arteries receive blood from the ventricles and their semilunar valves permit blood to be forced into the arteries, and prevent backflow from the arteries into the ventricles.

    It is caused by the closure of the semilunar valves (the aortic valve and pulmonary valve) at the end of ventricular systole and the beginning of ventricular diastole. As the left ventricle empties, its pressure falls below the pressure in the aorta. Aortic blood flow quickly reverses back toward the left ventricle, catching the pocket-like ...

    The function of the right heart, is to collect de-oxygenated blood, in the right atrium, from the body via the superior vena cava, inferior vena cava and from the coronary sinus and pump it, through the tricuspid valve, via the right ventricle, through the semilunar pulmonary valve and into the pulmonary artery in the pulmonary circulation ...

    The aortic valve is a valve in the heart of humans and most other animals, located between the left ventricle and the aorta.It is one of the four valves of the heart and one of the two semilunar valves, the other being the pulmonary valve.

    An aortic sinus, also known as a sinus of Valsalva, [1] is one of the anatomic dilations of the ascending aorta, which occurs just above the aortic valve.These widenings are between the wall of the aorta and each of the three cusps of the aortic valve.
