Hi everyone, I am starting a thread for official guide to mcat 2015 and the questions the book includes.
my first question (on page 76)
The radius of the aorta is about 1.0 cm and blood passes through it at a velocity of 30 cm/s. A typical capillary has a radius of about 4*10^-4 cm with blood passing through at a velocity of 5*10^-2 cm/s. using this data, waht is the approximate number of capillaries in a human body.
A. 1*10^4
B. 2*10^7
C. 4*10^9
D. 7*10^12
no idea how to do this
