The pancreas secretes bicarbonate, which helps to neutralize the acidic chyme that comes from the stomach into the small intestine. This neutralization is crucial because it creates an optimal pH environment for digestive enzymes to function properly in the small intestine.
Additionally, the gall bladder releases bile, which plays a key role in the digestion of fats. Bile contains bile acids that emulsify fats, allowing them to be more easily broken down by digestive enzymes. This process aids in the absorption of fat-soluble vitamins and fatty acids.
