There are not valves in the pulmonary artery or the aorta. However there are valves between these and the heart. Between the right ventricle and the pulmonary artery there is a valve referred to as the pulmonary semilunar valve. Between the left ventricle and the aorta there is a valve called the aortic semilunar valve.
What else can I help you with?
Semilunar valves open at the end of?
Semilunar valves are located at the base of both the pulmonary trunk (pulmonary artery) and the aorta
The entrance to the ascending aorta is guarded by?
The entrance to the ascending aorta is guarded by the semilunar valve. The semilunar valves are pocketlike structures attached at the point at which the pulmonary artery and the aorta leave the ventricles.
Which blood vessels does it pass through when it leaves the heart?
Systemic via the aorta - pulmonary via the pulmonary artery.
Which structure connects the aorta and the plumonary artery?
Arterial duct is the structure that connects the aorta and the pulmonary artery.
Is blood pressure higher in the aorta or the pulmonary artery?
Aorta -The pulmonary artery is just going to the lungs, so it has to be lower pressure.The aorta is where all the blood going to the rest of the body is pumped through.

Why are the valves at the entrance to the aorta and pulmonary artery called semilunar?
Both these valves are halfmoon shaped
Is the pulmonary artery not a branch of the aorta?
The pulmonary artery is not part of the aorta.
Where is the semi lunar valves found?
they are found at the entrance of the main aorta and the pulmonary artery
Do artery have valves?
Arteries do not have valves. Veins have valves.The only exceptions are the aortic valve where the aorta leaves the left ventricle of the heart, and the pulmonary valve where the pulmonary artery leaves the right ventricle.
Semilunar valve are found at the beginning of what two vessels?
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.
What semilunar valves regulate?
regulate the passage of blood from the ventricles into the pulmonary artery and the aorta
Does hepatic artery have valves?
No. No artery has valves, except for the aorta.
Is the pulmonary artery the largest artery?
No, the aorta is the largest artery.
The entrance to the ascending aorta is guarded by?
The entrance to the ascending aorta is guarded by the semilunar valve. The semilunar valves are pocketlike structures attached at the point at which the pulmonary artery and the aorta leave the ventricles.
