Q: If a 70 kg male has a total body water content of 42 L, what is the approximate volume of intracellular fluid (ICF)? Use the formula $$ICF = \frac{2}{3} \times Total\ Body\ Water.$$

$$ICF = \frac{2}{3} \times 42 = 28\ L$$

Accepted Answer

Digestive system

Question 18

Which of the following is a real-life example of a disease caused by failure of homeostatic mechanisms?

Accepted Answer
