(A.) A \"healthy\" systolic (during heartcontraction, the high number in 120/80) blood pressure is typically120 mmHg. What is this in Pascals? (Take the density of mercury tobe 14 g/ml and the acceleration due to gravity to be 10 m/s^2)_____ Pa

I tried converting mmHg to atm (760mmHg = 1atm) and thenconverting atm to Pa (1 atm = 101325 Pa) and got 15998.6842 Pa, butthis answer was incorrect.

(B.) Blood flows through the aorta, and therest of the body, at a rate of 5 liters per minute.

If the aorta has a diameter of 2 cm, what is the speed of theblood flowing through it? _____ m/s

(C.) Given that the blood flow through the bodyis 5 liters per minute, estimate the number of capillaries thereare in the body using the following. Assume the diameter eachcapillary is 10 micrometers and the speed of blood through them is0.03 cm/s

(D.) During a ventricle contraction, theaverage pressure pushing blood into the aorta is 100 mmHg. What isthis pressure in Pascals? (use the density of mercury at 14 g/mland the acceleration due to gravity of 10 m/s^2)

______ Pa

(E.) During a contraction, the heart pumps 75ml of blood into the Aorta. Given the pressure above, how much workis done (in Joules) on the blood by the heart during acontraction?

(F.) Assuming a heart rate of 60 beats perminute, how many Calories (kilocalories) are burned justcirculating blood during a day. (Take the approximation of 4 Joulesper calorie.)
