WebJul 22, 2024 · Nephron tubules absorb and secrete different small molecules and ions at specific locations. The action in which molecules enter the tubules via the Bowman’s capsule and interstitial tissue is called absorption. Molecules that return to the interstitial fluid from the filtrate is called reabsorption.
