Question

The sodium (Na+) potassium (K+) pump is a protein channel in the nephron. The pump moves sodium out of the nephron and moves potassium into the nephron. The nephron is exchanging molecules with the Group of answer choices A. capillary B. adrenal gland C. collecting duct D. urethra

Answer 1

Option A, Capillary

Water and other substances move in cor-ordination with the sodium and potassium ion movement. The water moves into peritubular capillaries and vasa recta under the influence of osmolarity and concentration gradients. Na+ ion when moves from PCT into the interstitial spaces between cells, it reduces its concentration gradient in the peritubular capillary. As a result of this water will flow passively into the capillary. This is known as obligatory water reabsorption

Thus, option A is correct
