Question

Vasa efferentia connects the
A. Testis with epididymis
B. Kidneys with epididymis
C. Testes with urinogenital ducts
D. None of the above

Answer 1

Hint: Vasa efferentia is a secondary sex organ of male reproductive system.

Complete Answer:
- The male reproductive system consists of a pair of testes suspended in a scrotum which the primary sex organ. The accessory ducts, glands and external genitalia are considered as secondary sex organs.
- Each testis has total \[250\] compartments called testicular lobules and each lobule contains highly coiled seminiferous tubules.
- The four accessory ducts are: rete testis, vasa efferentia, epididymis, vas deferens. Rete testis connects the seminiferous tubules of testis to vasa efferentia which opens into the epididymis.
- Epididymis is situated in the posterior part of the testis which opens into the vas deferens. Vas deferens opens into the urethra through an ejaculatory duct. It is a common opening for the secretion of urine and sperm.
 -Seminal vesicles, prostate gland, bulbourethral gland are present to protect and nourish the sperm.

Hence, the correct answer is (A) vasa efferentia connects the testis with epididymis.

Note: The pathway of sperm ejaculation is given by the following diagram.
Seminiferous tubules
 rete testis ⟶ vasa efferentia ⟶ epididymis ⟶ vas deferens ⟶ ejaculatory duct ⟶ urethra.
