This one gets a little gruesome! In this topic we identify the different types of teeth and their functions, including how these vary from animal to animal and animal to human. We explore the body parts associated with the digestive system, such as mouth, tongue, teeth, oesophagus, stomach and intestine and describe their special functions. We compare and contrast the digestive system of a herbivore with a carnivore, using knowledge of human digestive system and we explore foods to keep us healthy.
