Which of the blood vessel is the largest in earthworm and possess valves?
1 Dorsal blood vessel
2 Sub-neural blood vessel
3 Ventral blood vessel
4 Supra oesophageal blood vessels
Explanation:
A The dorsal blood vessel is the largest vessel. In earthworm collects blood throughout the anterior body of the earthworm. Contractile peristalsis pushes blood from anterior to posterior directions through the dorsal vessel.

Regarding blood circulationit may be said that in Pheretima the dorsal vessel is a
1 collecting vessel in firsttwo segments and distributing vessel in other
2 distributing vessel in firstfive segments and distributing vessel in other
3 collecting vessel in first thirteen segments and distributing vessel in intestinal region
4 distributing vessel in first thirteen segments and collecting vessel in intestinal region
Explanation:
D In the region behind 13th segments blood laden with digested nutruient and \(\mathrm{O}_{2}\) is collected in the dorsal vessel while in anterior region of bodysome of this blood in supplied by dorsal vessel to various parts.

Spermathecae in earthworm is :
1 for producing sperm
2 for storage of sperm obtained from male earthworm during copulation and used in future
3 both a and b
4 none of the above
Explanation:
B In earthwormsspermatheca is an organ of the female reproductive tract and it is an internal sac that is pear shaped. The main function of this is to receive and store the sperm from the male component of the body during copulation.

1 1-3 yrs
2 2-6 yrs
3 \(3 \frac{1}{2}-10 \mathrm{yrs}\)
4 \(61 / 6\) - \(15 y \mathrm{yrs}\)
Explanation:
C Worms are the invertebrates that belong mostly to the phylum platyhelminthes and Annelida. Worm like invertebrates have a lifespan that varies according to species. For instanceearthworms such as the Red wiggler worms live between 4-5 years. Some worms get life span more than 10 years too.
