- Acid secretion is a characteristic feature of the stomach.
- The stomach secretes hydrochloric acid (HCl), which aids in digestion by creating an acidic environment.
- This acidic environment helps in breaking down food and activating digestive enzymes like pepsin.
- It also plays a role in killing harmful bacteria and pathogens ingested with food.
Additional Information
- The buccal cavity is the mouth and is involved in the initial stages of digestion but does not secrete acid.
- The large intestine is primarily involved in water absorption and does not secrete acid.
- The small intestine is responsible for nutrient absorption and secretes alkaline fluids to neutralize stomach acid.
- The stomach's mucosa contains specialized cells such as parietal cells that produce hydrochloric acid.
