- B) HCl secretion
- C) mucus secretion
- D) nutrient absorption
- E) enzyme secretion
The stomach is a muscular organ located on the left side of the upper abdomen. The stomach has 3 main functions such as temporary storage for food, that passes from the esophagus to the stomach where it is held for 2 hours or longer. mixing and breakdown of food by contraction and relaxation of the muscle layers in the stomach, also the digestion of food.
The major activities by stomach involves mechanical digestion, HCl secretion, mucus secretion and enzyme secretions. Whereas the nutrient absorption is carried out in the small intestine.
Mechanical digestion involves physically breaking the food into smaller pieces. While in the HCl secretion, the main constituent of gastric acid is hydrochloric acid which is produced by parietal cells (also called oxyntic cells) in the gastric glands in the stomach. For mucus secretion, the consumption of spicy foods can spark excess mucus production in the nasal passages. Besides, for enzyme secretion, the enzymes that are secreted in the stomach are gastric enzymes
Nutrients are foods essential compounds to life and health, providing us with energy to regulate chemical processes. Six major nutrients are Carbohydrates (CHO), Lipids (fats), Proteins, Vitamins, Minerals, Water
