Physiology SI 4

What is the concentration of a cell?

• 300 M

• 350

• 250

• 200

Why is water transported into a hypertonic compartment?

• Osmotic pressure is higher in hypertonic compartment

• osmotic pressure is higher in hypotonic compartment

• osmotic pressure is lower in hypertonic compartment

• osmotic pressure is lower in hypotonic compartment

What is the normal range of osmolarity?

• 200-350

• 280-300

• 100-200

• 300-350

A solution that is less than 280 M is said to be?

• hypertonic

• hypotonic

• isotonic

a solution greater than 300 is said to be

• isotonic

• hypertonic

• hypotonic

osmoles of solute/ kg of solvent

• osmolality

• osmolarity

Molecule Y binds to receptor Y and stimulates the receptor. Molecule Y is a...

• agonist

• blocker

• antagonist

• molecule Y MUST bind to receptor Z

Receptor X increases blood pressure. If an antagonist binds to receptor X, what can we expect?

• increase in blood pressure

• decrease in blood pressure

• no change

Why is water is transported out of hypotonic compartments?

• hypotonic compartments have high osmotic pressure

• hypertonic compartments have low osmotic pressure

• Hypotonic compartments have a lower osmotic pressure

• hypertonic compartments have high osmotic pressure

t or f lymph is hypotonic to interstitial fluid
