Answer:
The circulatory and respiratory systems work together to circulate blood and oxygen throughout the body. Air moves in and out of the lungs through the trachea, bronchi, and bronchioles. Blood moves in and out of the lungs through the pulmonary arteries and veins that connect to the heart.

The correct answer to the question: An abnormal sound (murmur) due to narrowing or stenosis of the mitral valve might be heard during:____, would be, A: Diastole.
Explanation:
It is first important to know that a murmur comes from the sound the blood makes as it passes either through a hardened tissue, like is the case of stenosis of a valve, or because it leaks back from where it came, due to regurgitation, because the valve is defective and cannot close properly. During the cardiac cycle, there is a process of systole, and of diastole, that ensure the filling and expulsion of the blood inside the heart towards the body, and from the body into the heart, so that a constant flow is ensured. In the process of filling and emptying, two sets of valves, the mitral and tricuspid, and the aortic and pulmonary, open and close to allow blood flow towards the different chambers of the heart, and out into the blood vessels of the body, and prevent the blood from returning towards where it came. In the case of mitral stenosis, which is the toughening of the mitral valve of the heart, the blood flowing through it makes a murmuring sound that can be caught up through a stethoscope. This sound is prominent during diastole, and that is why medically this murmur is known as a diastolic murmur.
Stenting is an alternative to endarterectomy for treatment of carotid artery stenosis, but long-term efficacy is uncertain.
What is Stenting?
A stent is a small tube made of wire mesh. It holds open an artery and stays there indefinitely.
If a coronary artery (a blood vessel that supplies an accumulation narrows the heart muscle. Plaque is a fatty buildup that can lessen the blood flow. if there is less blood flow Chest pain may be caused by damage to the heart muscle.If a clot develops and entirely obstructs the a portion of the heart muscle's blood flowthe heart attack happens.Stents maintain coronary artery patency.and lower the risk of having a heart attack.
A stent is deployed by collapsing it and placing it over the
the balloon catheter. It is then brought close to the obstruction.
