Question

During pregnancy, what cardiovascular system changes are normal in the second trimester? a) Increased heart rate b) Decreased blood volume c) Lower blood pressure d) Enlarged aorta

Answer 1

a) Increased heart rate

During the second trimester of pregnancy, it is normal for a woman's heart rate to increase. This is due to the increased demand for blood and oxygen by both the mother's body and the developing fetus. The heart has to work harder to meet these increased demands, resulting in an elevated heart rate.
