REGULATION OF WATER AND ELECTROLYTE LEVELS IN INTRACELLULAR FLUID (ICF)

Question 1

What plays a critical role in regulating ICF composition?

Answer 1

Plasma membrane

Question 2

True/False

IF and ICF hydrostatic and colloid pressures regulate water transfer between ECF and ICF

Answer 2

True

Question 3

True/False
colloid osmotic pressures are chief regulators of blood transfer across cell membranes, and these are directly related to the electrolyte concentration gradients maintained across cell membranes

Answer 3

False
colloid osmotic pressures are chief regulators of WATER transfer across cell membranes, and these are directly related to the electrolyte concentration gradients maintained across cell membranes

Question 4

In a hypertonic solution a cell shrinks by osmosis because H2O leaves the cell. What is this called?

Answer 4

Crenation

Question 5

In a hypotonic solution a cell swells and bursts because osmosis causes too much H2O to enter the cell. What is this called?

Answer 5

Lysis
