WebCountercurrent multiplication moves sodium chloride from the tubular fluid into the interstitial space deep within the kidneys. Although in reality it is a continual process, the way the countercurrent multiplication process builds up an osmotic gradient in the interstitial fluid can be thought of in two steps: The single effect. WebThe major factors that contribute to high solute concentration into the renal medulla are: 1. Active transport of sodium ions and cotransport of potassium chloride out of the thick ascending limb of LOH into medullary interstitium. 2. Active transport of ions from the collecting ducts into the medullary interstitium. ADVERTISEMENTS: 3.
