Pharmacology Passive Diffusion Quiz

The concentration gradient, which moves drugs from areas of higher concentration to areas of lower concentration.

Water-soluble drug molecules, which are lipid insoluble.

It is concentration gradient dependent, does not require energy, and is not a saturable process.

Drug movement from high to low concentration without energy or carrier proteins and with low specificity.

Drug movement through passive diffusion is not limited by the number of available carriers, unlike some other processes.

Water-soluble drugs pass through tiny channels (pores) due to their size & blood flow.

Aqueous diffusion depends on the drug's molecular weight and blood flow, not its lipid solubility or pH.

Passive diffusion is not selective; it's not blocked by other substances.
