digestive mucosa
It’s the mucosa, not the submucosa.
Mucosa-associated lymphoid tissue (MALT) functions as a part of the immune system, protecting mucosal surfaces in the body from infections. It helps to produce antibodies and immune cells that can respond to pathogens that enter the body through mucosal tissues such as the respiratory or digestive tracts.
The muscular contractions move the food, mix it with digestive juices, and bring the digesting food in contact with the mucosa where absorption takes place.
Jellyfish have a simple digestive system. They have a digestive cavity with cells lining the wall that carry out the digestive function.
