In the kidney, parathyroid hormone (PTH) blocks reabsorption of phosphate in the proximal tubule while promoting calcium reabsorption in the ascending loop of Henle, distal tubule, and collecting tubule. Parathyroid hormone (PTH) promotes absorption of calcium from the bone in 2 ways. The rapid phase brings about a rise in serum calcium within minutes and appears to occur at the level of the osteoblasts and osteocytes.
Site: Calcium is absorbed from the duodenum and upper jejunum primarily by an active vitamin D-dependent transcellular process; in the ileum, the predominant process is passive vitamin D-independent, paracellular diffusion. Absorption of Ca ++ in the ileum is about one-third as rapid in the upper small intestine.he colon seems to conserve Na+ more efficiently than the small intestine: it absorbs about 95% of luminal sodium, as compared to 75% absorbed by the small bowel. Bicarbonate is secreted against an electrochemical gradient. Chloride absorption is linked to bicarbonate secretion and sodium transport.
