Question

Blood from seminal vesicles and gonads is collected by

• A. Dorsal vessel
• B. Ventral vessel
• C. Subneural vessel
• D. Lateral esophageal vessel

Answer 1

The correct option is D Lateral esophageal vessel

In earthworm, the sub-neural vessel in the 14${}^{th}$ segment divides into two lateral-esophageal vessels running on the lateral sides of the stomach and esophagus in close contact. The blood is collected by the lateral esophageal vessels from gonads and seminal vesicle and is put into the supra-esophageal vessel through these loops.

So, the correct answer is option D.
