Certified Hemodialysis Technician Practice Exam

Question: 1 / 400

What does osmosis refer to in a biological context?

Movement of solutes across a membrane

Diffusion of solvent through a semipermeable membrane from low-to-high solute concentration

Osmosis in a biological context specifically pertains to the movement of solvent, particularly water, across a semipermeable membrane. This process occurs from an area of lower solute concentration to an area of higher solute concentration. The purpose of osmosis is to equalize solute concentrations on the two sides of the membrane, which is crucial for maintaining homeostasis in cells and tissues.

In practical terms, this dynamic is especially important in the context of kidney function and hemodialysis. During dialysis, the osmotic gradient created helps to remove waste products and excess fluids from the blood, effectively purifying it. The significance of osmosis highlights how solvents balance concentrations of solutes, leading to the essential processes like nutrient absorption and waste elimination in biological systems.
