Think: wringing out a wet rag. Explain convection in hemodialysis - ANSWER-Solutes DRAG across the semipermeable membrane with fluid Explain diffusion in hemodialysis - ANSWER-PARTICLES move from HIGH concentration to LOW concentration Explain osmosis in hemodialysis - ANSWER-FLUID moves LOW concentration to HIGH concentration What are the kidneys' excretory functions? - ANSWER-To normalize electrolytes, remove wastes, provide fluid and nutrient balance How do we replace normal excretory kidney functions? - ANSWER-By using acid concentrate to help normalize electrolytes and ultrafiltration to provide fluid balance What is the function of acid concentrate - ANSWER-Provides the concentration gradient for diffusion and helps normalize electrolytes
