17. Answer briefly V

Explain the structure of nephron.

 

a. Each kidney consists of more than one million nephrons. TrueFalse

 

b. The uriniferous tubules, also known as glomerulusnephrons, are structural and functional units of the kidneys.

 

c. Each nephron consists of a glomerular capillariesrenal corpuscle and renal tubule. It comprises a cup-shaped structure called Bowman's capsuleMalpighian corpuscle, which includes a glomerulus, which is a series of capillaries.

 

d. Blood enters the glomerular capillaries through afferent arteriolesefferent arterioles and leaves through efferent arteriolesafferent arterioles.

 

e. The Bowman's capsule continues as the  renal tubule, divided into fourthree sections. This includes proximal convoluted tubule, U-shaped hairpin loop or the loop of Henleglomerulus, and the distal convoluted tubule.

 

f. The distal convoluted tubuleproximal convoluted tubule opens into the collecting tubule. The nitrogenous wastes are drained into the renal pelvisrenal cortex and then into the urethraureters, deposited in the urinary bladder. The urethraureters later expels this urine out.
