Answer:
The composition of food leaving the stomach and entering the small intestine would be affected in several ways. Firstly, the food would not be broken down into smaller pieces, which would make it difficult for the enzymes in the small intestine to digest it. This would result in the incomplete digestion of food and a decrease in soaking up of essential nutrients. Secondly, the absence of hydrochloric acid would stop the stomach from breaking down proteins, which are needed for the body to build and repair tissues. This would lead to a deficiency of amino acids, which could result in weakness, fatigue, and other health problems. Finally, the lack of acid in the stomach would remove the barrier against harmful bacteria, the risk of infection and illness increasing. The absence of hydrochloric acid in the stomach would significantly impair the digestive process, leading to a variety of health issues.
