What advantages are there in supplying pulmonary circulation with blood at low pressure than that of systemic circulation?

Because the pulmonary circuit only pumps blood to the lungs and back to oxygenate it before it is sent round the rest of the body. The Systemic circuit must pump the blood everywhere else in the body and therefore has a much larger distance to cover which is why it needs more force and pressure.

∙ 11y agoin pulmonary circulation blood passes through the heart only once that is blood is pumped from the heart to the lungs only and in most of the cases the heart does not even exist here we talk of substitute heart.
while in systemic circulation ,blood is pumped from the (true)heart to the lungs and backs to the heart ,this means blood passes through the heart twice.

What is importance of pulmonary circulation?
Pulmonary circulation is blood supply to the lungs. This is important for two reasons. First, like all organs, the lungs have to have oxygen themselves in order to function. Second, blood has to go through the lungs in order to become oxygenated. The pulmonary vein is the only vein in the body that carries oxygenated blood. Systemic circulation is important for two reasons also. First, and simplest, is the fact that every cell in the body has to have oxygenated blood to function. Without oxygenated blood, the cells will begin to infarct, or die. Second, systemic circulation creates what's called perfusion pressure. Simply put, it's the pressure required to allow the organs to pull the oxygen from the blood. As blood pressure goes down, the body's ability to pull in oxygen from the blood also decreases.
Why is there bounding peripheral pulse in patent ductus arteriosus?
The output runoff through the PDA from the left ventricle's output to the pulmonary circulation causes a lower diastolic pressure resulting in a lower than normal pressure in diastole. This gives the feeling of a bounding pulse when the heart beats due to the increased difference between the systolic and diastolic pressure and is interpreted as a bounding pulse in the peripheral vessels.
The greater the the pulse pressure the lower the pressure gradient driving blood from the aorta through the systemic circulation?
True
What would happen if the pulmonary artery was to be cut and bleed?
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 does the lub-dub sound represent?
The first heart sound or "lub" results from closure of the tricuspid and mitral valves. It is a rather low-pitched and a relatively long sound which, as indicated in, represents the beginning of ventricular systole. The second heart sound, or "dub," marks the beginning of ventricular diastole. It is produced by closure of the aortic and pulmonary (pulmonic) semilunar vanes when the intraventricular pressure begins to fall
Is the pulmonary circulation a high pressure circulation?
No
Is the pulmonary circulation a high or low pressure circulation?
It is both: Higher pressure incoming and Lower pressure on the extruding end.
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.
What diagnosis means that the blood pressure in the pulmonary circulation is high?
Pulmonary hypertension, which is a serious illness and can lead to heart failure.
What are the two main circulatory routes in the body?
You have lesser circulation or the pulmonary circulation. Blood goes to lungs in this system from the right side of heart. You have greater circulation or the systemic circulation. Blood goes to all over the rest of body through this circulation. The amount of blood that flows is same in both the systems. You have about 25/15 mm of Hg pressure in pulmonary circulation. You have about 120/80 mm of Hg pressure in systemic circulation.
How is the heart involved in pulmonary circulation?
Right side of the heart is involved in pulmonary circulation. This circulation is called, at times, as lesser circulation, as against the greater or systemic circulation. Blood that flows through the lesser and greater circulation is same in amount. But there is gross difference between the two. You have interstitial compartment in the systemic circulation. This is maintained through high blood pressure there. You do not have the same in pulmonary circulation. What you need here is simple blood flow, with out formation of the interstitial compartment. For that you have blood systolic blood pressure of about 25 mm of mercury. The blood pressure in the capillaries is about 15 mm of the mercury. The oncotic pressure of the blood proteins is about 22 mm of mercury. So very little fluid is leaked out to keep the alveoli wet. Some times in diseased condition more fluid is leaked out in the alveoli, to give rise to pulmonary oedema.
Is the left side of the heart is high pressure or low pressure?
The left side of the heart is part of a high-pressure circuit. The left side of the heart must pump blood throughout the body, requiring higher pressure than the pulmonary circulation.
What does an elevated pulmonary wedge pressure indicate?
an elevated pulmonary wedge pressure indicate that the pressure in the left atrium is evevated .
What is idiopathic pulmonary arterial hypertension?
Primary pulmonary hypertension is generally classified as a disease of the lung, related to high blood-pressure. Essentially, the increased pressure causes some pulmonary arteries and veins to work at drastically different rates than others, creating an imbalance that can cause fatigue, shortness of breath, fainting, and a persistent cough.
What conditions are contraindicated for myocardial resection?
right heart failure, elevated left ventricular enddiastolic pressures, and pulmonary hypertension (high blood pressure in the circulation around the lungs).
What has the author D H Glaister written?

What develops within the pulmonary capillaries when the pressure increases?
pulmonary edema
