Pulmonary Circulation (Lungs)
Pulmonary circulation is the movement of blood
from the heart to the lungs and back to the heart
again. Pulmonary circulation includes both arterial
and venous circulation.
Blood without oxygen is pumped to the lungs
from the heart (arterial circulation). Oxygen-rich
blood moves from the lungs to the heart through
the pulmonary veins (venous circulation).
Pulmonary circulation also includes capillary
circulation. Oxygen you breathe in from the air
passes through your lungs into your blood
through the many capillaries in the lungs.
Oxygen-rich blood moves through your
pulmonary veins to the left side of your heart and
out of the aorta to the rest of your body.
Capillaries in the lungs also remove carbon dioxide
from your blood so that your lungs can breathe
the carbon dioxide out into the air.
let's make this simple and short
pulmonary artery;*contain deoxygenated blood*
pulmonary vein contain: contain oxygenated blood
They are correct because the arteries carries oxygenated blood except the pulmonary artery while the vein carries deoxigenated blood except the pulmonary vein

How Does Blood Travel Through Your Body?
PrintEmail
As the heart beats, it pumps blood through a system of blood vessels called the blood circulatory system. The vessels are elastic tubes that carry blood to every part of the body and are made up of four subsystems.
Arterial Circulation (Arteries)
Arterial circulation is the part of your overall blood circulatory system that involves arteries, like the aorta and pulmonary arteries.
Arteries are blood vessels that carry blood away from your heart. Healthy arteries are strong and elastic. They become narrow between beats of the heart, and they help keep your blood pressure consistent. This helps blood circulate efficiently through your body.
Arteries branch into smaller blood vessels called arterioles (ar-TEER-e-ols). Arteries and arterioles have strong, flexible walls that allow them to adjust the amount and rate of blood flowing to various parts of your body.
Venous Circulation (Veins)
Venous circulation is the part of your overall blood circulatory system that involves veins, like the vena cavae and pulmonary veins. Veins are blood vessels that carry blood to your heart.
Veins have thinner walls than arteries. Veins can widen as the amount of blood passing through them increases.
Capillary Circulation
Capillary circulation is the part of your overall blood circulatory system where oxygen, nutrients, and waste pass between your blood and parts of your body.
Capillaries connect the arterial and venous circulatory subsystems. Capillaries are very small blood vessels.
The importance of capillaries lies in their very thin walls. Unlike arteries and veins, capillary walls are thin enough that oxygen and nutrients in your blood can pass through the walls to the parts of your body that need them to work normally.
Capillaries' thin walls also allow waste products like carbon dioxide to pass from your body's organs and tissues into the blood, where it's taken away to your lungs.
Veins have thinner walls than arteries. Veins can widen as the amount of blood passing through them increases.
Pulmonary Circulation (Lungs)
Pulmonary circulation is the movement of blood from the heart to the lungs and back to the heart again. Pulmonary circulation includes both arterial and venous circulation.
Blood without oxygen is pumped to the lungs from the heart (arterial circulation). Oxygen-rich blood moves from the lungs to the heart through the pulmonary veins (venous circulation).
Pulmonary circulation also includes capillary circulation. Oxygen you breathe in from the air passes through your lungs into your blood through the many capillaries in the lungs. Oxygen-rich blood moves through your pulmonary veins to the left side of your heart and out of the aorta to the rest of your body.
Capillaries in the lungs also remove carbon dioxide from your blood so that your lungs can breathe the carbon dioxide out into the air.
pulmonary artery carries deoxygenated blood from the auricles to the lungs while pulmonary vein carries oxygenated blood from the lungs to the heart. Note: pulmonary vein is the only vein that carries oxygenated blood
pulmonary artery brings back blood from the lungs after oxygynation and therefore is oxygen-rich than blood in the pulmonary vein...i don't think they are correct
