There are two semilunar valves: 1. pulmonic valvewhich is located at the opening of the pulmonary artery; and 2. aortic valve which is located at the opening of the aorta.
There are semi-lunar valves in the human heart: the aortic valve and the pulmonary valve. They prevent blood from flowing back into the ventricles.
at places where blood leaves via the aorta and pulmonary arteries. (pulmonary trunk)
t the places where blood leaves via the aorta and pulmonary arteries
Semilunar valves are found throughout the body in veins, as they prevent backflow of deoxygenated blood. In the heart, there are two semilunar valves, the pulmonary semilunar valve and the aortic semilunar valve. The pulmonary semilunar valve is the gateway to the pulmonary artery, which then goes to the lungs. The aortic semilunar valve is the gateway to the aorta, which distributes oxygenated blood to the rest of the body.
There are 4 valves in your heart (2 atrioventricular and 2 semilunar). There is an AV valve between the right atrium and the right ventricle (Right AV valve or tricuspid valve) and an AV valve between the left atrium and the left ventricle (Left AV valve or bicuspid valve). There are also two semilunar valves; one between the right ventricle and the lungs (pulmonary semilunar valve) and one between the left ventricle and the aorta (aortic semilunar valve). The main purpose of the valves is to prevent backflow of blood in the heart. There are things called the chordae tendinae and papillary muscle that help control the opening and closing of the valves as blood flows through them. There are also valves in the veins. These keep the blood from flowing backwards as the blood pressure is very low.
You have the atrioventricular valves that are the valves separating each atrium from the ventricles. The right AV valve is the tricuspid valve, while the left AV valve is the bicuspid/mitral valve. There are also two valves that lead from the heart to the pulmonary and aortic arteries. These are the pulmonary and aortic valves. They are both semilunar valves because of their shape.
Heart valves, specifically atrioventricular and semilunar valves, prevent the backflow of blood and help it flow in one direction through the heart. The valves open and close in response to pressure changes during the cardiac cycle.
The four valves in the heart are: * the two semi-lunar valves - one at the stem of the aorta, the other is found at the trunk of the pulmonary artery. * The tricuspid valve is on the right-hand side of the heart. * The bicuspid valve is on the left side of the heart.

Valves can be found in the heart aswell as the veins
There are atrioventricular valves on each side of the heart that keep blood from flowing from the ventricles back up into the atria. There are also semilunar valves that prevent blood from flowing from the pulmonary arteries and aorta back into the right and left ventricles, respectively.
