1. Consider two blood vessels that have the same length andresistance. Given these pressure
differentials along their lengths, which one will have the greatestflow? Why?
Vessel 1: P1 = 100 mmHg, P2 = 25 mmHg
Vessel 2: P1 = 500 mmHg, P2 = 400 mmHg
2. A healthy student requires a cardiac output of 4000mL perminute to support resting activity. The interval between beats is0.8 secs.
In moderate exercise, such as walking, the student’s heart rateclimbed to 135BPM, end diastolic volume decreased to 100mL andejection fraction was 80%.
i. What is cardiac output?
ii. Why would end diastolic volume decline under thesecircumstances?
iii. What other changes may occur with exercise?
