Why the pulmonary veins carrying the oxygenated blood and not the pulmonary artery?
it's a pulmonary VEIN because the blood isn't under as much pressure (because it has yet to get to the heart) where as the pulmonary artery is coming straight from the heart so is under more pressure. (the pressure is caused by the heart's contractions)
Which artery in the heart is the largest and why?
Aorta..has to pump blood to the entire body. Pulmonary artery has to pump to the lungs...much less of a distance.
What is the difference between pulmonary artery and pulmonary vein?
The pulmonary artery carries blood from the heart to the lungs. The pulmonary vein carries blood to the heart from the lungs. Unlike all other veins and arteries in the body the pulmonary artery has de-oxygenated blood and the pulmonary vein has oxygenated blood.
How does the pulmonary circulation work in your body?
Much like the systemic circulation, but at a lower pressure: Blood flows from the right ventricle through pulmonary artery to lungs where the gases are exchanged to pulmonary vein to left atria.
Why would pulmonary arteries be relatively small at the fetal stage of development?
The pulmonary artery is the artery that takes blood to the lungs to get oxygen. Because the fetus doesn't breathe, but rather gains oxygen from its mother, it doesn't need this artery as much, and so it doesn't develop as fast, so that more of the energy used for growth can be put where it's needed.
The veins that empty the blood from the lungs to the heart?
The pulmonary artery carries the blood from the right side of the heart to the lungs. The pulmonary vein then returns the oxygenated blood to the left side of the heart where it is pumped along the aorta->arteries->arterioles->capillary bed. It is then returned to the heart via venules->veins->inferior/superior vena cava.
What happens if the ductus arteriosus does not fully close after birth?
The infant will have abnormal blood flow between the aorta and pulmonary artery (those are the two major blood vessels in the heart). The ductus arteriosus is not needed after birth, since the lungs now fill with air (before birth, the pulmonary artery supplied blood to the lungs and aorta to be sent to the rest of the body).

What veins travel from the lungs to the heart in?
There are actually two sets of arteries and veins going to and from the lungs. The first set are the pulmonary artery and vein. The pulmonary artery takes blood from the right atrium, takes it to the lungs where the blood is oxygenated and loses some of its carbon dioxide. It is then taken back to the heart by the pulmonary vein, which is the only vein in the body to carry fully oxygenated blood. The other set of vessels carrying blood to the lungs are referred to the bronchial vessels, and supply oxygen and nutrients to the lung tissue itself. These arise from the thoracic aorta or intercostal vessels and run alongside the airways (trachea, bronchi, bronchioles, etc) and much of the blood is returned via the pulmonary vein due to a large bronchial-to-pulmonary shunt that exists via many anastomoses between the two blood supplies.
How will a victim bleed to death within minutes?
It's certainly possible if an artery or vein is lacerated. Laceration is multiple cuts (as opposed to a stab wound) - therefore the multiple wounds would allow much more blood to be lost.
What circumstances should you touch an open wound with your fingers?
When possible, you should use a clean dry cloth, even a shirt, scarf, necktie, etc. However, if an artery has been cut, you will likely have to use your bare hand(s) until you can grab or obtain a cloth. Any time a wound bleeds profusely, or the wound is pumping blood (sign of arterial bleed), the wound requires immediate pressure.NOTE: The scalp has a huge supply of blood vessels. So head wounds bleed much more even for minor cuts. But a few minutes of pressure should slow or stop the bleed from a head wound.
How is blood collected from a donor?
Blood is collected from the donor by inserting a large needle into a vein in the arm. Usually, one of the larger veins near the inside of the elbow is used. A tourniquet is placed on the upper arm
