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
What else can I help you with?
If water were poured into the vena cava through which vessels will it emerge from the heart?
it enters the right atrium via the vena cava, then goes down pass the tricuspids valves and into the right ventricle, from there it goes up pass the semi lunar valve at the base of the pulmonary artery and come out from there.
Who carries oxygenated blood?
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.
Trace a drop of blood from the skin of face to the right atrium?
Here we go! [First, the pulmonary circuit.] R atrium; R ventricle; pulmonary artery (L or R); arteriole; capillary adjacent to an alveolus of lung; venule; pulmonary vein [Now the blood returns to the heart for the systemic (body) circuit.] L atrium; L ventricle; aorta; R iliac artery; arteriole; capillary in a toe of the R foot; venule; R femoral vein; vena cava; back to the R atrium
How can you trace a drop of blood from the left anterior tibial vein to the right radial artery?
The left anterior tibial vein drains into the veins leading into the inferior vena cava, which empties in the right atrium. The right atrium pumps into the right ventricle. The right ventricle pumps this deoxygenated blood into the pulmonary trunk which splits into two branches left and right which transport the doexygenated blood on to vasculature in the lungs. This circuit essentially turns around in the alveolar capillaries where gas exchange occurs, oxygenating this blood and turning it from blue to red. This blood drains into a return system, draining this oxygenated blood from capillary to venule to vein, gathering in the right and left pulmonary vein. (vein doesn't always mean blue blood. Vein means that it is returning to the heart and artery means leaving the heart. In the body system this means that arteries are red and veins are blue, but in the pulmonary circuit, it's the opposite with regard to color. Don't rely on blood color to remember this, rely on direction of transport to and from the heart). The blood enters the left atrium through the mitral valve and into the left ventricle which pumps through the aortic valve into the aorta which feeds the systemic circuit. Off of the aorta there are many branches leading to areas of the body such as the head, upper torso, legs, etc. One of these branches, the brachiocephalic trunk, will split into two branches. The one on the thumb side of the forearm is the right radial artery.
What is the purpose if the coronary artery?
I think that you are talking about Coronary artery that supplies oxygenated blood to the walls of the heart.If it is blocked by the fat content there would be no supply of oxygenated blood and hence we experience heart strokes.
What happens when pulmonary vein and artery connect?
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.
What would happen to the blood pressure in the pulmonary artery if more blood is drived to the lungs during exercise?
The pressure in the pulmonary artery increases during exercise if the cardiac output increases.
What artery carries deoxygenated blood from the heart?
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.
What happens if an artery is nicked?
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.
Where would blood go when it leaves through pulmonary artery?
to the lungs
Where would blood go when it leaves through the pulmonary artery?
...to the lungs.
How would you define pulmonary circulation?
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.
If a cardiologist inserts a catheter into a patient's right femoral artery which arteries would the tubevhave to pass though in order to reach the entrance to theb left coronary artery?
the pulmonary artery
What are the four major blood vessel s that is connected to the heart?
Vena cava, pulmonary vein, pulmonary artery, and aorta. (I would double check spelling...)
What is the only artery that carries oxygen-poor called?
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.
Damage to the semilunar valves on the right side of the heart would interfere with blood flow to which vessel?
PULMONARY ARTERY
What would happen if the cartoid artery was removed?
you wil die
