Answer 2

Sol: Animals who have true coelom which is lined by mesoderm onthe inside part of the body wall and around the gut are called as coelomates. True coelomates in which body cavity originates by splitting of mesodermal tissue during gastrulation are called as schizocoelomates. Sometimes in schizocoelomates such as arthropods and molluscs, schizocoelom is filled by blood. This is called as haemocoel.
