explain digestion in long terms
Answer (1)
Answer:Digestion is the complex biological process through which the body breaks down the food we eat into smaller, absorbable components that can be used for energy, growth, and repair. This process involves both mechanical digestion (physical breakdown of food) and chemical digestion (enzymatic breakdown of nutrients).It begins in the mouth, where food is chewed and mixed with saliva, which contains enzymes like amylase that start breaking down carbohydrates. The chewed food, now called bolus, travels down the esophagus into the stomach, where strong acids and enzymes like pepsin begin digesting proteins. The stomach churns the food into a semi-liquid mixture called chyme.Chyme then moves into the small intestine, the main site of digestion and absorption. Here, digestive juices from the pancreas (enzymes for fats, proteins, and carbs) and liver (bile for fat emulsification) further break down the food. The nutrients are absorbed through the walls of the small intestine into the bloodstream.Whatever is not absorbed moves into the large intestine, where water and minerals are absorbed, and the remaining waste is compacted into feces. Finally, the waste is eliminated from the body through the rectum and anus.Digestion is essential for converting food into nutrients like glucose, amino acids, fatty acids, vitamins, and minerals, fueling every cell and function in the body.
