Question

Sarah is resting in a chair for a long period of time; her calf and thigh muscles are totally relaxed. Next to her, Priya is also resting in a chair, but she is wiggling, kicking, tapping, and vibrating her legs; resulting in an pattern where her calf and thigh muscles are alternating between relaxed and contracted states. If all else is equal, who has the higher stroke volume, Sarah or Priya?
A) Sarah has a higher stroke volume.
B) Priya has a higher stroke volume.
C) Sarah and Priya have the same stroke volume because they are both seated.
D) No significant difference in the stroke volume between Sarah and Priya can be predicted based on this information.

Answer 2

Answer:

B) Priya has a higher stroke volume.

Explanation:

Stroke volume (SV) is the volume of blood pumped from the left ventricle per beat of the heart.

Stroke volume is also known to have a relationship with the general heart function such that it decreases in the presence of diseases such as hemorrhages, hypothyroid etc.

The stroke volume increases during exercises or movement of parts of the body. Priya is resting in a chair, but she is wiggling, kicking, tapping, and vibrating her legs which significantly is the reason why she has a higher stroke volume.
