D) renal corpuscle
E) peritubular capillaries
Solution
The structure that is NOT part of the blood circulation in the kidney is:
B) loop of Henle
Explanation for each option:
A) Vasa recta - Incorrect. The vasa recta are capillaries that run parallel to the loop of Henle and are part of the blood circulation in the kidney.
B) Loop of Henle - Correct. The loop of Henle is a part of the nephron involved in the concentration of urine, but it is not directly part of the blood circulation.
C) Glomerulus - Incorrect. The glomerulus is a network of capillaries involved in the filtration of blood in the kidney.
D) Renal corpuscle - Incorrect. The renal corpuscle includes the glomerulus and Bowman's capsule and is involved in the filtration of blood.
E) Peritubular capillaries - Incorrect. The peritubular capillaries are part of the blood circulation in the kidney and surround the renal tubules to facilitate reabsorption and secretion.
Summary:
The loop of Henle is not part of the blood circulation in the kidney.
