The pulmonary or pulmonic valve (a semilunar valve) controls blood flow from the right ventricle to the "pulmonary trunk" that branches into the two pulmonary arteries carrying blood to the lungs.
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.
right atrium -> right ventricle -> pulmonary artery -> pulmonary vein -> left atrium -> left ventricle -> aorta
Pulmonary arteries carry deoxygenated blood from the right ventricle.
the pulmonary artery :)
Right Antrium
The pulmonary valve is the tricuspid valve between the right ventricle and the pulmonary artery. It prevents blood from flowing down the artery back into the right ventricle.
The right atrium and the left atrium. It actually lies between the right ventricle and the pulmonary artery, where it prevents the backflow of blood from the artery back into the heart during diastole (the resting period of the heartbeat)
The pulmonary artery carries blood from the right ventricle to the lungs. This is the unusual artery in that it carries deoxygenated blood.

through seminular valve at the time of ventricle contaraction blood from right ventricle is pumped to lungs.
The pulmonary semilunar valve is a heart valve that separates the right ventricle from the pulmonary artery. It functions to prevent the backflow of blood from the pulmonary artery back into the right ventricle during the heart's pumping cycle.
right atrium -> right ventricle -> pulmonary artery -> pulmonary vein -> left atrium -> left ventricle -> aorta
Right ventricle and pulmonary artery
The pulmonary artery takes blood from the right ventricle into the lungs; the pulmonary vein collects blood from the lungs back to the left atrium of the heart.
The semilunar valves prevent backflow of blood into the ventricles of the heart. They close to ensure that blood flows in one direction only, from the ventricles to the arteries (pulmonary artery and aorta).
Pulmonary arteries carry deoxygenated blood from the right ventricle.
