What are insensible losses
8.5-10.5
What is Ca or Calcium
The ability of ALL solutes to cause an osmotic driving force that promotes water movement from one compartments to another
What is tonicity?
It is the increase in urine output caused by the excretion of substances, such as Flu-, mannitol or contrast agents in the urine.
