Mouth

Answer 8

Mechanical + chemical digestion occurs
3 pairs of salivary glands

Wave like contractions of muscles that move food along the gastrointestinal tracts towards stomach

Question 13

Stomach

Answer 13

Site of food storage and protein digestion, holds food while it mixes with acid and enzymes to breakdown
Physical and chemical digestion
