### Human Digestive System Diagram This educational section comprehensively details the human digestive system, identifying and labeling the vital organs as depicted in the given anatomical diagram. #### Labeled Organs: - **a**: Nasal Cavity - **b**: Oral Cavity (Mouth) - **c**: Pharynx - **d**: Esophagus - **e**: Liver - **f**: Gallbladder - **g**: Stomach - **h**: Pancreas - **i**: Duodenum - **j**: Small Intestine - **k**: Cecum - **l**: Appendix - **m**: Rectum - **n**: Nostril - **o**: Epiglottis - **p**: Diaphragm - **q**: Transverse Colon - **r**: Ascending Colon - **s**: Descending Colon - **t**: Sigmoid Colon - **u**: Anal Canal - **v**: Anus - **w**: Appendix (repeated label, possibly an error in the diagram) ### Functionality and Explanation of Major Organs: 1. **Nasal and Oral Cavities (a & b)**: - Act as entry points for air (nasal cavity) and food (oral cavity) respectively. 2. **Pharynx (c)**: - A muscular tube that directs food from the mouth to the esophagus. 3. **Esophagus (d)**: - A muscular tube that transports food from the pharynx to the stomach. 4. **Liver (e)**: - Produces bile, which helps in the digestion of fats. 5. **Gallbladder (f)**: - Stores and concentrates bile from the liver. 6. **Stomach (g)**: - Secretes acid and enzymes that digest food. It churns food into a semi-liquid form called chyme. 7. **Pancreas (h)**: - Produces digestive enzymes and bicarbonate, which are released into the small intestine. It also regulates blood sugar by producing insulin. 8. **Duodenum (i)**: - The first section of the small intestine, where most chemical digestion occurs. 9. **Small Intestine (j)**:
