What is a good example of a flowchart of the human digestive system?

FOOD INTAKE
     |
     v
[MOUTH]
  - Teeth chew (mechanical digestion)
  - Saliva adds amylase (begins breaking down starch)
     |
     v
[PHARYNX / THROAT]
  - Food swallowed; epiglottis closes the airway
     |
     v
[ESOPHAGUS]
  - Muscular tube carries food via peristalsis (wave-like contractions)
     |
     v
[STOMACH]
  - Gastric acid (HCl) + pepsin break down proteins
  - Churning turns food into semi-liquid chyme (2-4 hours)
     |
     v
[SMALL INTESTINE] <---- [PANCREAS releases digestive enzymes]
  - Duodenum: bile + pancreatic enzymes digest fats, proteins, carbs
  - Jejunum: most nutrient absorption here  <---- [LIVER produces bile → stored in GALLBLADDER]
  - Ileum: absorbs vitamin B12 and bile salts
     |
     v
[LARGE INTESTINE (COLON)]
  - Absorbs water and electrolytes from remaining matter
  - Gut bacteria ferment remaining material
     |
     v
[RECTUM]
  - Stores solid waste (feces) until elimination
     |
     v
[ANUS]
  - Feces expelled from the body

Accessory organs (not part of the tube but essential):

• Liver produces bile, detoxifies blood
• Gallbladder stores and concentrates bile
• Pancreas produces digestive enzymes and insulin
