Major Glands Associated with the Alimentary Canal and their Functions:
The major glands associated with the alimentary canal of man play crucial roles in the process of digestion by secreting various enzymes and substances. Here are the main glands and their functions:

Salivary Glands:
- Salivary glands, including the parotid, sublingual, and submandibular glands, produce saliva.
- Saliva contains enzymes like amylase that break down carbohydrates in the food.
- Saliva also contains mucus that helps in lubricating the food for easy swallowing.

Liver:
- The liver produces bile, which is stored in the gallbladder.
- Bile aids in the digestion and absorption of fats by emulsifying them into smaller droplets.
- It also helps in neutralizing stomach acid and eliminating waste products from the body.

Gallbladder:
- The gallbladder stores and concentrates bile produced by the liver.
- When needed, the gallbladder releases bile into the small intestine to aid in fat digestion.

Pancreas:
- The pancreas secretes digestive enzymes like lipase, protease, and amylase into the small intestine.
- These enzymes help in breaking down fats, proteins, and carbohydrates for absorption.
- The pancreas also produces bicarbonate to neutralize stomach acid in the small intestine.

Gastric Glands:
- Gastric glands in the stomach secrete gastric juice that contains hydrochloric acid and pepsin.
- Hydrochloric acid helps in the breakdown of food and kills bacteria, while pepsin digests proteins.
In conclusion, the major glands associated with the alimentary canal of man work together to ensure the proper digestion and absorption of nutrients from the food we consume. Each gland plays a specific role in the digestive process, contributing to the overall efficiency of the digestive system.
