The pulmonary artery is the one which carries blood from the right ventricle to the lungs. It is the only artery in the body that carries deoxygenated blood. The blood is carried at a pressure, usually less than 30mmHg. So, if the pulmonary artery was to be cut and bleed, the person would die when blood volume fell below the minimum necessary. This wouldn't take long, either. Between actual blood loss, and the sudden decrease in pressure such an injury would cause death in approximately 2 minutes
If water were poured into the vena cava, it would ultimately flow into the right atrium of the heart, then into the right ventricle, and finally be pumped out through the pulmonary artery to the lungs for oxygenation. It would not directly emerge from the heart via any vessel.
Deoxygenated blood leaves the heart by way of the Pulmonary Artery. It passes through the lungs losing carbon dioxide and absorbing oxygen by conversions in the haemoglobin. The oxygen rich blood returns to the heart via the Pulmonary Vein. From the heart it goes to the body, The most oxygen rich blood would be in the Pulmonary Vein just after it leaves the lungs.
The drop of blood from the skin of the face would enter small blood vessels called venules and merge into larger veins, eventually draining into the superior vena cava. The superior vena cava then delivers the deoxygenated blood to the right atrium of the heart, completing the journey.
To trace a drop of blood from the left anterior tibial vein to the right radial artery, the blood would first travel through the anterior tibial vein, then it would enter the popliteal vein, continuing through the femoral vein, then the inferior vena cava, followed by the right atrium of the heart, then the right ventricle, and finally be pumped out through the pulmonary artery to reach the lungs for oxygenation. From the lungs, it would return through the pulmonary vein to the left atrium, pass through the left ventricle, and be pumped out through the aorta to eventually reach the right radial artery.
The purpose of the coronary artery is to supply oxygen-rich blood to the heart muscle. This blood flow is essential for the heart to function properly and meet its high energy demands. If the coronary artery becomes blocked or narrowed, it can lead to serious conditions such as a heart attack.
This is called a shunt. One that occur between the Pulmonary artery and the Pulmonary vein, would be a left to right shunt. So what would happen? The blood from the Pulmonary vein (having the high pressure) would enter the Pulmonary artery. The results would be that the blood just goes back to the lung for another cycle with be deoxygenated.
The pressure in the pulmonary artery increases during exercise if the cardiac output increases.
Arteries carry oxygenated blood away from the heart. Arteries probably CAN carry deoxygenated blood if a person draws blood from a vein, then injects it into an artery. That would be very stupid though.
To quote another answer to a different question:"The pulmonary artery is the one which carries blood from the right ventricle to the lungs. It is the only artery in the body that carries deoxygenated blood. The blood is carried at a pressure, usually less than 30mmHg. So, if the pulmonary artery was to be cut and bleed, the person would die when blood volume fell below the minimum necessary."What_would_happen_if_the_pulmonary_artery_was_to_be_cut_and_bleedSeeing how this is probably the artery your talking about, it would take more time to bleed out, as you will be bleeding at a slower rate. However, if you are somehow incapacitated, it can prove just as deadly.
to the lungs
...to the lungs.
pulmonary circulation the flow of blood from the right ventricle through the pulmonary artery to the lungs, where carbon dioxide is exchanged for oxygen, and back through the pulmonary vein to the left atrium.
the pulmonary artery
Vena cava, pulmonary vein, pulmonary artery, and aorta. (I would double check spelling...)
If it's carrying oxygen-poor blood, it must be going to the lungs, so I would guess you would call that the pulmonary artery.
PULMONARY ARTERY
you wil die
