Answer: 3) Decreased blood flow from the ventricle to the aorta
Step-by-step explanation:
Aortic stenosis is a condition characterized by the narrowing of the aortic valve, which obstructs the flow of blood from the left ventricle of the heart to the aorta. This narrowing results in a decreased amount of blood being able to pass through the valve and into the aorta, leading to reduced blood flow and increased pressure in the left ventricle. It does not result in increased blood flow, normal blood flow, or regurgitation of blood from the aorta back into the ventricle.
