A patient has an end-diastolic volume of 125 ml. A heart attack has weakened her left ventricle so it can pump a stroke volume of only 40 ml. Calculate her end-systolic volume.
A) 85 ml
B) 3.1 ml
C) 5000 ml
D) 165 ml
E) There is not enough data given to calculate the end-systolic volume.
Question 2
Why are inguinal hernias generally associated with males?
