Question: 1 / 400

What effect does stenosis have on blood flow?

Increases blood flow to the heart

Prevents blood flow from reaching the heart

Blocks blood flow, requiring more forceful heart function

Stenosis refers to the narrowing of a blood vessel or heart valve, which impairs normal blood flow. The presence of stenosis means that blood must be moved through a constricted passage, leading to an increase in the resistance against which the heart has to pump. This condition requires the heart to exert more forceful contractions to maintain adequate blood flow to the body's tissues and organs.

In cases of significant stenosis, the heart can struggle to deliver sufficient blood, potentially leading to a condition known as heart failure over time if the demands become too great. Therefore, the correct understanding is that blockage caused by stenosis leads to increased workload on the heart to compensate for the restricted blood flow.

The other choices do not accurately convey the specific implications of stenosis on blood flow dynamics or heart function.
