In Pheretimagizzardbuccal cavitypharynx oesophagus and pharyngeal nephritides receive the blood from which blood vessel
1 supra oesophageal
2 lateral oesophageal
3 dorsal blood
4 subneural
Explanation:
C In Pheretima posthumathe dorsal blood vessel is considered as dorsal tubular heart. This blood vessel is a collecting blood vessel behind \(13^{\text {th }}\) segmentit works as the distributing vessel. The blood flows in it from backward to forward.

The location of lymph glands in Pheretima is
2 \(10^{\text {th }}\) to \(20^{\text {th }}\) segments
3 \(26^{\text {th }}\) to the last segments
4 \(13^{\text {th }}\) segments
Explanation:
C In Pheretimalymph gland are present on both sides of dorsal blood vessel from segment \(26^{\text {th }}\) and those behind it.

Forests of nephridia are present in
1 pharyngeal region
2 clitellar region
3 anal region
4 None of the above
Explanation:
B Nephridia lie scattered on the entire inner or Parietal surface of body wall in segmentexcept the first two . There are 200-250 nephridia in each segment but in the segments of clitellum (segments 14 to 16) their number increases to more than 2000 constituting the forests of nephridia.
