It becomes thicker
after it is done with the pulmonary circulation it goes directly to the lungs
pathway of blood circulatwed by pulomanary
The pressure in the pulmonary artery increases during exercise if the cardiac output increases.
aortaAND..pulmonary trunk
The pulmonary valve ensures one-way flow of blood from the right ventricle to the pulmonary artery. It opens to allow blood to be pumped into the pulmonary artery during ventricular contraction, and then closes to prevent backflow of blood into the right ventricle during relaxation.
Heart pumps out blood into major vessels(aorta,pulmonary arteries)
Gasses are exchanged (CO2 is lost & O2 is gained).
The right ventricle empties into the pulmonary arteries and the left ventricle empties into the aorta.
aorta and pulmonary artery
Blood entering the pulmonary circuit is deoxygenated. Blood leaving the pulmonary circuit is oxygenated.
The average amount of blood pumped from the right ventricle during a normal pulmonary circulation is about 5- 8 liters.
The pulmonary artery and pulmonary vein originates in the heart. What is different about them is that the pulmonary artery carries deoxygenated blood (blood without oxygen) as supposed to other arteries, which carry oxygenated blood. And the pulmonary vein carries oxygenated blood unlike other veins, which carry deoxygenated blood.
