According to the Fick Principle, the quantity of blood pumped through the lungs depends on the following variables (in milliliters):

b = quantity of oxygen used by the body in one minute
a = quantity of oxygen per liter of blood that has just gone through the lungs
v = quantity of oxygen per liter of blood that is about to enter the lungs

In one minute, 

Amount of oxygen used = Amount of oxygen per liter * Liters of blood pumped.

If C is the number of liters of blood pumped through the lungs in one minute, then

(a) Find the number of liters of blood pumped through the lungs in one minute if a = 160, b = 200, and v = 125.
(b) Find the approximate change in C when a changes from 160 to 161, b = 200, and v = 125.
(c) Find the approximate change in C when a = 160, b changes from 200 to 201, and v = 125.
(d) Find the approximate change in C when a = 160, b = 200, and v changes from 125 to 126.
(e) A change of 1 unit in which quantity of oxygen produces the greatest change in the liters of blood pumped?
