I think that a basic experiment involves a minimum of two participants group(s). Simple or basic experiment are ones that researchers use to determine if changes in one variable might lead to changes in another variable. In these experiments looking at the effectiveness of a new medication, for example, study participants may be random.
Answer:
1- dilate
2- perfusion
Explanation
when blood pressure increase the arterioles dilate (become smaller) so that cells can absorb the oxygen from the blood easily. perfusion will be altered or slowed down. (The perfusion is the passage of fluid through the circulatory system. )
Answer:
The correct answer is: E) a bruit sound when auscultated with a stethoscope.
Explanation:
Mitral valve regurgitation is a condition in which the mitral valve - <em>responsible for the blood flow from the left atrium to the left ventricle </em>- doesn't close as tightly as it should, which can result in backward blood flow. If the condition worsens, this defect can lead to heart failure.
Mitral valve regurgitation may not have symptoms at first but, as the condition progresses, shortness of breath, fatigue, and palpitations can occur. When auscultated with a stethoscope, a bruit sound can be heard, which corresponds to the abnormal blood flow that is occurring.
