Question

Arrange the following ducts pertaining to male reproductive system starting from seminiferous tubules. Ducts given:
• [(A)] Vas deferens
• [(B)] Vasa efferentia
• [(C)] Rete testis
• [(D)] Epididymis Choose the correct answer from the options given below:

• A. \((A),\ (B),\ (C),\ (D)\)
• B. \((B),\ (C),\ (D),\ (A)\)
• C. \((D),\ (A),\ (B),\ (C)\)
• D. \((C),\ (B),\ (D),\ (A)\)

Hint:

Path of sperms: \[ \text{Seminiferous tubules} \rightarrow \text{Rete testis} \rightarrow \text{Vasa efferentia} \rightarrow \text{Epididymis} \rightarrow \text{Vas deferens} \]

Answer 1

The Correct Option is D

Sperms formed in seminiferous tubules pass through a definite sequence of ducts in male reproductive system.
Step 1: Seminiferous tubules open into: \[ \text{Rete testis} \] Thus first duct is: \[ (C) \]
Step 2: Rete testis opens into: \[ \text{Vasa efferentia} \] Thus next duct is: \[ (B) \]
Step 3: Vasa efferentia open into: \[ \text{Epididymis} \] Thus next duct is: \[ (D) \]
Step 4: Epididymis continues as: \[ \text{Vas deferens} \] Thus final duct is: \[ (A) \] Therefore, the correct sequence is: \[ (C)\rightarrow(B)\rightarrow(D)\rightarrow(A) \] Option analysis:
• Option (A): Incorrect order
• Option (B): Incorrect order
• Option (C): Incorrect order
• Option (D): Correct Hence: \[ \boxed{\text{(D)}} \]
