Pathophysiology Unit 1 questions with answers 2024

Pathophysiology Unit 1cation - correct answer A positively charged ion anion - correct answer A negatively charged ion diffusion - correct answer Movement of molecules from an area of higher concentration to an area of lower concentration. hydrostatic pressure - correct answer water and solutes move through membrane because of greater pushing force on one side of the membrane osmosis - correct answer Diffusion of water through a selectively permeable membrane osmolarity - correct answer Measure of the number of milliosmoles per liter of solution or the concentration of molecules per volume of solution osmolality - correct answer Measure of the number of milliosmoles per kilogram of water or the concentration of molecules per weight of water osmotic pressure - correct answer the amount of hydrostatic pressure required to oppose the osmotic movement of water colloid osmotic pressure (oncotic pressure) - correct answer overall osmotic effect of colloids, such as plasma proteins distinguish between active and passive transport mechanisms - correct answer Passive transport does not require the use of energy for molecules and ions to travel across a membrane. It includes osmosis, filtration, and diffusion.
