Question
Total blood volume is roughly equal to about 7% of his total body weight. Assume that 1 kilogram of blood occupies a volume of 1 liter. I an typical 70 kg male, this corresponds to a total blood volume of about 5 liters (0.07 x 70 kg =4.9 L).
a. Calculate the total blood volume (in L) in a 200-lb man.
b. if the man in the above question has a hematocrit of 52%, what is his blood plasma volume (in L)?
c. Calculate the total blood volume (in L) in a 130-lb woman.
d. if the woman in the above question has a hematocrit of 41%, what is her blood plasma volume (in L)?
Explanation / Answer
Answer:
Total blood volume = ~7% of total body weight
Density of blood (based on given information) = 1 kg/l
a) Calculate the total blood volume in a 200-lb man
b. if the man in the above question has a hematocrit of 52%, what is his blood plasma volume (in L)?
c. Calculate the total blood volume (in L) in a 130-lb woman.
d. if the woman in the above question has a hematocrit of 41%, what is her blood plasma volume (in L)?
