30.Filtration of the blood takes place at A. PCT B. DCT C. Collecting ducts D. Malpighian body
Option D Each nephron has two parts glomerulus and renal tubule. Glomerulus is a tuft of capillaries formed by afferent arteriole. The renal tubule begins with a double walled cup-like structure called Bowman's capsule, which encloses glomerulus. Glomerulus along with Bowman's capsule, is called Mapighian body or renal corpuscle. The tube continues further to form PCT, loop of Henle and DCT. The first step in urine formation is the filtration of blood which is carried out by the Malpighian body.
