food enters body through mouth which leads to buccal cavity buccal cavity → inside mouth and the beginning of the alimentary canal.
Adaptations of Mouth:
- Teeth: break UP large pieces of food into smaller pieces. this increases the SA to V ratio of food to enzymes so that enzymes can act on food more efficiently.
- salivary glands: secrete salivary amylase into mouth
- Tongue: mixes food with saliva and pushes food to the back of the mouth to be swallowed. also rolls into balls.
Pharynx: part of alimentary canal that connects buccal cavity to esophagus and larynx(voice box) also leads to trachea.(windpipe)
