Circulatory system: A system that lets blood
transport throughout the body.
Respiratory system: lets the animal bring oxygen
in the body and releases carbon dioxide.
Urinary system: The organism will create fluid
waste that will be release in the form of urine.
Digestive system: The organism is able to break
