Nephron
Papillary duct or DCT The thing in this question that stands out to me is "part of the nephron". Actually the parts of a nephron only include renal corpuscle, proximal convoluted tuble, nephron loop, and distal convoluted tubule. I would a say the answer, if you read it the way I am taking it, is DCT. The papillary duct does follow the DCT but is not part of the nephron.
filtration takes place only at glomeruli part of nephron and nowhere else.
The Bowman's capsule is the part of the nephron that filters substances from the glomerulus. It surrounds the glomerulus and is responsible for collecting the filtrate that is produced.
Urethra has three regions in males, the prostatic urethra, membranous urethra, and the spongy urethra.
