Solution
The correct option is B
A- (i)Spermatogenic cells (ii) Sertoli cells
B- (iii)Vasa efferentia, (iv) Rete testis.
The testes are the primary sex organs in males, which are located in a pouch-like structure called the scrotum, outside the abdominal cavity. Testis contains about 250 compartments of testicular lobules, containing highly coiled seminiferous tubules.
Each seminiferous tubule is lined inside by two types of cells-
1.Spermatogenic cells/or male germ cells- Undergo series of divisions to form spermatozoa.
2.Sertoli cells or Nurse cells- Tall, large columnar cells which provide nourishment to the developing spermatids.
The seminiferous tubules are closed at one end and on the other side, it joins to form a network, the rete testis. This carries the sperms from seminiferous tubules to efferent ducts. Vasa efferentia carries sperms to the epididymis where the sperms mature.
