Blood is then pumped through the semilunar valve and into the pulmonary artery.
From the en.wikipedia.org
Here, it is pumped out of the pulmonary semilunar valve and travels through the pulmonary artery to the lungs.

It then travels through the mitral valve to the left ventricle, from where it is pumped through the aortic semilunar valve to the aorta.
From the en.wikipedia.org
These return waves create the dicrotic notch displayed in the aortic pressure curve during the cardiac cycle as these reflected waves push on the aortic semilunar valve.
From the en.wikipedia.org
With age, the aorta stiffens such that the pulse wave is propagated faster and reflected waves return to the heart faster before the semilunar valve closes, which raises the blood pressure.

It then travels through the mitral valve to the left ventricle, from where it is pumped through the aortic semilunar valve to the aorta and to the rest of the body.
