- 3. This movement, essential for swallowing and digestion, relies on rhythmic contractions that do not require conscious control.
- 5. Secreted by the pancreas, this enzyme requires emulsified substrates to efficiently perform its role.
- 6. A carbohydrate-digesting enzyme present in both saliva and pancreatic juice that initiates chemical digestion before food reaches the stomach.
- 8. Though it produces hormones, its primary digestive role involves delivering a juice rich in enzymes and a compound that neutralizes stomach acid.
Down
- 1. These microscopic extensions greatly enhance the efficiency of absorption by dramatically increasing the surface area of a specific organ.
- 2. , This enzyme works best in acidic environments and begins breaking down complex food molecules early in protein digestion.
- 4. This final and longest part of the small intestine is rich in structures that specialize in absorbing digested nutrients into the bloodstream.
- 5. Found at the core of each villus, this structure transports the products of lipid digestion into a different circulatory system than amino acids or sugars.
- 7. This versatile organ performs roles in metabolism, detoxification, and nutrient storage, and connects to the small intestine via a key blood vessel.
