Answer 1

a) PTH and calcitrol - 20) hormones that increase concentrations of Ca2+ in the ECF.

b) ICF - 17) contains approximately 2/3 of total body water.

c) hyponatremia - 29. Caused by hyperhydration

d) metabolic acid - 21) by product of cellular metabolism that reduces pH

e) sodium - 22) primary ion contributing to ECF osmolarity.
