Question 1
pts
Water movement between the intracellular fluid compartment and the extracellular compartment is
primarily a function of
antidiuretic hormone.
Correct!
osmotic forces.
plasma oncotic pressure.
hydrostatic forces.
The movement of water between ICF and ECF compartments is primarily a function of osmotic
forces. (Osmosis and other mechanisms of passive transport are discussed in Chapter 1.)
Question 2
pts
What is a major determinant of the resting membrane potential necessary for transmission of nerve
impulses?
Correct!
The ratio between intracellular K+ and extracellular potassium
The ratio between intracellular K+ and extracellular Na+
The ratio between intracellular Na+ and extracellular K+
The ratio between intracellular Na+ and extracellular sodium
The ratio of K+ in the ICF to K+ in the ECF is the major determinant of the resting membrane
potential, which is necessary for the transmission and conduction of nerve impulses, maintenance
of normal cardiac rhythms, and skeletal and smooth muscle contraction.
