Urine osmotic pressure

Urine permeation concentration, also known as urine permeation, urine permeation, refers to the total number of particles in the kidney that excrete all solutes in the urine, such as electrolytes, urea, sugars, and proteins. The measurement of urinary permeability more accurately reflects the concentration function of the kidney than the measurement of urine relative density. The kidneys regulate the balance of body fluid penetration by concentrating or diluting urine. The urine permeation concentration reflects the relative excretion rate of the solute and water by the kidney, and is not affected by the size and properties of the solute particles, but only related to the number of solute particles.
