Describe the digestive system of freshwater mussel ​

Answer 1

Answer:

Digestive gland is dark brown to greenish in colour and surrounds the stomachs and opens into it through many ducts. The intestine is coiled and passes through the gonad and pericardial cavity to end in rectum that opens by anus at the base of the exhalent siphon.

Explanation:

Internal organ systems include an open circulatory system powered by a heart; a digestive system that consists of mouth, stomach, gut, and anus; a decentralized nervous system that controls movement of the foot and adductor muscles; and reproductive organs that usually occur separately in male and female mussels.
