The nurse is reviewing the anatomy and physiology of the nephron with a group of nursing students. The nurse educator asks a nursing student to describe the function of the loop of Henle
What is the best explanation for the function of the loop of Henle? A) Filters water, wastes (urea), glucose, and salts out of the blood
B) Glucose, amino acids, and salts are actively transported across membranes and returned to the blood
C) Concentrates salts by reabsorbing water
D) Reabsorbs sodium, water, and the remainder of glucose
C
Feedback:
Loop of Henle concentrates salts by reabsorbing water. The glomerulus filters water, wastes (urea), glucose, and salts out of the blood. The proximal convoluted tubule actively transports glucose, amino acids, and salts across membranes and returns them to the blood. The distal convoluted tubule reabsorbs sodium, water, and the remainder of glucose.
