Vena Cava has valves, if im not wrong, but pulmonary veins definitely do not have valves.
Why pulmonary veins have no valves
yes
The path of blood flow starting at the pulmonary veins: -pulmonary veins -left atrium -bicuspid valve -left ventricle -Pulmonary semi lunar valve -Aorta
The right ventricle pumps blood into the pulmonary artery.
True.
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.
Right atrium > tricuspid valve > right ventricle > pulmonary semilunar valve > pulmonary arteries > lungs > pulmonary veins > left atrium > bicuspid valve > left ventricle > aortic semilunar valve > aorta > arteries > arterioles > capillaries > venues > veins > superior/inferior vena cava > right atrium (again)
right atrium --> tricuspid valve --> right ventricle --> pulmonary semilunar valve --> pulmonary arteries --> lungs --> pulmonary veins --> left atrium --> bicuspid valve --> left ventricle --> aortic semilunar valve --> aorta --> arteries and capillaries --> cells --> venules, veins, vena cava --> right atrium -->thoughtfulobserver
Pulmonary artery which contains pulmonic valve and aorta which contains aortic valve.
Pulmonary valve to the pulmonary arteries to the lungs to the pulmonary veins to the left atrium thru the mitral valve to the left ventricle thru the aortic valve to the aorta to the capillary beds to the superior and inferior cavaFrom the right atrium through the tricuspid valve to the right ventricle through the pulmonary valve to the pulmonary trunk to the right and left pulmonary arteries, to the capillary beds of the right and left lungs, to the pulmonary veins, to the left atrium of the heart through the mitral valve, to the left ventricle through the aortic semilunar valve, to the capillary beds, to the systemic veins, to the superior vena cava, and inferior vena cava, which enter the right atrium of the heart.Inflowing part of right ventricleGoes to the Right Ventricle.After entering the right atrium from the body and through the tricuspid vavle, it goes into the right ventricle....Pulmonic valves, pulmonary trunk, to the lungs...
Pulmonary veins derive from the lungs. And reside in the cardiovascular system.

Veins carry deoxygenated blood back to the right atrium of the heart, which sends it through the tricuspid valve to the right ventricle to the pulmonary semilunar valve to the pulmonary arteries to the lungs (to become oxygenated and get rid of waste gases) to the pulmonary veins to the left atrium of the heart through the bicuspid valve to the left ventricle through the semilunar aortic valve to the ascending aorta to the aortic arch and out to the body. So the only veins that are oxygenated are the pulmonary veins that carry the oxygenated blood from the lungs to the left atrium of the heart. They are still called veins because they carry blood TO the heart. Thus, the only deoxygenated blood in arteries is also the pulmonary arteries, because they carry the deoxygenated blood AWAY from the heart to the lungs. All veins must carry blood toward the heart and all arteries must carry blood away from the heart.
vena cava -> right atrium-> through the right atrioventricular valve -> right ventricle -> through the Plumonary semi-lunar valve -> Plumonary trunk -> out the pulmonary artery -> lungs -> pulmonary veins -> left artrium -> through the left atrioventricular valve -> left ventricle -> through the aortic valve -> aorta -CB
