In a healthy person, the blood pressure in the arteries of the lungs is usually lower than the pressure of the blood in the rest of the body because the blood is pumped from the weaker right side of the heart because of a shorter distance from the heart into the lungs.
In a person who has disease of the heart or lungs, blood pressure rises in the arteries of the lung and damage can occur over time to the large and small arteries in the lungs. The walls of the blood vessels thicken and are less able to transfer oxygen and carbon dioxide to and from the blood. When less oxygen gets into the blood, pulmonary arteries become narrower. A spiral of increasing pressure on the lung's arteries begins producing a condition called cor pulmonale.

What is the difference of the blood coming from the heart and blood coming from the lungs?
Blood coming from the lungs has lower pressure while that from the heart has higher pressure. Blood coming from the lungs also has higher oxygen content and lower carbon dioxide content compared to that coming from the heart.
Explain why the blood flowing to your lung is different from those are flowing out?
Answer:Blood flowing to your lungs is full of carbon dioxide, which gets exchanged in your lungs and the blood flowing out of your lungs is clean/purified with oxygen in it.
How does blood leaving the lungs differ from the blood entering the lungs?
Blood coming from the lungs has lower pressure while that from the heart has higher pressure. Blood coming from the lungs also has higher oxygen content and lower carbon dioxide content compared to that coming from the heart.
What is the flow of blood between the heart and lungs called?
The flow of blood from the heart to the lungs and back to the heart is called the pulmonary circulation.The blood flowing from the heart to the lungs would be deoxygenated and blood flowing towards the heart from the lungs would be oxygenated.
Is the blood flowing from the heart to the lungs rich or poor in oxygen?
poor
Does the heart get oxygen and nutrients from the blood flowing through it?
no. it gets it from the lungs
Do your lungs have a blood pressure separate from the heart blood pressure?
The blood pressure in the alveoli and bronchial linings are necessarily lower than the arterial system as a whole. Blood returning from the body is pumped by the right ventricle of the heart into the pulmonary arteries of the lungs, where it will replenish its oxygen levels. Blood then moves to the left ventricle of the heart for distribution to the rest of the body. This left ventricle compression is what determines the blood pressure measurements we commonly take. Excessive pressure in the pulmonary arteries can be caused by narrowing of the blood vessels, by diseases of the heart and lungs, and by external influences such as drugs.
Do vein valves control the veins?
No. They prevent back flow as the blood pressure is much lower on the venous side. The blood has to get to the heart so it can be pumped to the lungs.
What happens when pressure is lower inside the lungs than outside the lungs?
atmospheric
What does the alveole do?
Looks like a bubble in the lungs; its function is to exchange gasses between the air inhaled and the blood flowing through the lungs. (Mostly oxygen into blood and CO2 out of the blood.)
Why the pressure in blood vessels pulmonary vein and inferior vena cava is less than the aorta and pulmonary artery?
In a healthy person, the blood pressure in the arteries of the lungs is usually lower than the pressure of the blood in the rest of the body because the blood is pumped from the weaker right side of the heart (a shorter distance from the heart) into the lungs.
Where is that blood flowing to the left artreium enter?
to left ventricle from where it goes to lungs for oxygenation.
