hydra is a coelentrate marine organism. it has a unique digestive system which is both extracellular & intracellular. first the ingested food is digested extracellularly & then intracellularly. extracellular digestion takes place in the body cavity of hydra which is called coelentron by the digestive enzymes secreted by gland cells of endodermal layer which is called gastrodermis. then the partially digested food is engulfed by the cells of gastrodermal layer in the form of food vacuoles. further digestion takes place in these food vacuoles.

extracellular digestion enables and animal to digest much larger prey then intracellulary digestion allows.

Unicellular eukaryotes achieve intracellular digestion through the process of endocytosis, phagocytosis, and use of food vacuoles and lysosomes. A paramecium is an example of an organism that uses intracellular digestion vs. humans which utilize extracellular digestion.

Antibodies can attack both extracellular and intracellular antigens.
