Extract

Mucus, leaving the pyloric duct in a continuous flow, is conveyed over the epithelium of the aboral part of the pyloric stomach. There nutrients are resorbed and concentrated into the haemal system, which is in close contact with this part of the stomach. It is supposed that this material consists of nutrients in complex form especially destined for the use of gonad development.
