A histological specimen of kidney shows a structure which consist of a glomerulus
with fenestrated capillaries and bilayer epithelial capsule. Specify this structure:
a. Collecting tubules
b. Distal tubule
c. Renal corpuscle
d. Henle's loop
e. Proximal tubule
Mark the following statements as true or false. If a statement is false, correct it to make a true statement. a. The kidneys are retroperitoneal and covered by three layers of connective tissue. b. Internally, the kidneys consist of an outer renal medulla, a middle renal pelvis, and an inner renal cortex. c. The first capillary bed of the kidneys is the peritubular capillaries,which are fed by the afferent arteriole and drained by the efferent arteriole. d. Filtrate flows from the renal corpuscle to the distal tubule, the nephron loop, the proximal tubule, and into the collecting system.
Which of the following is not associated with the renal corpuscle?
EQuestion options:
a) glomerular capillåry
b) fenestrated capillary
d) peritubular capillary
