Question | Answer |
---|---|
Liver has how many lobes | 4 Lobes |
Process of breaking down complex food into simple nutrients body can absorb and convert to energy. | Digestion |

Part of both digestive and respiratory systems | Pharynx |
Transport from throat to stomach | Esophagus |
Small container with thick (acid)folding layers, expands with food, digestion per churning and chemcial breakdown. Gastric secretions (very acidic) will mix with food and create chyme | Stomach |
