Figure 13.1Mechanisms of Ca²⁺ transport in the intestine and kidney.

a. Intestinal Ca2+ absorption.

a

Intestinal Ca²⁺ absorption. At high luminal Ca²⁺ levels (mM range), Ca²⁺ will be absorbed predominantly via the paracellular route. At low luminal levels, Ca²⁺ is being absorbed via the transcellular route as follows: (1) luminal Ca²⁺ is first absorbed (more...)

b. Renal reabsorption of Ca2+.

b

Renal reabsorption of Ca²⁺. About 70% of filtered Ca²⁺ is being reabsorbed via the paracellular route in the proximal tubular and about 25% in the loop of Henle. About 5%–10% of filtered Ca²⁺ is reabsorbed in the distal tubules (distal convoluted (more...)
