Question
The digestive system
The digestive system A is made up of organs such as the stomach, kidneys, and liver. B is responsible for converting food to smaller, more absorbable molecules.
Solution
The digestive system is indeed responsible for converting food into smaller, more absorbable molecules. This process begins in the mouth where food is broken down into smaller pieces by the teeth and enzymes in saliva. The food then travels down the esophagus and into the stomach, where it is further broken down by stomach acid and enzymes.
The partially digested food then moves into the small intestine, where most of the digestion and absorption of nutrients occurs. The walls of the small intestine are lined with tiny finger-like projections called villi, which increase the surface area for absorption. Enzymes in the small intestine break down the food into its smallest components: proteins are broken down into amino acids, fats into fatty acids and glycerol, and carbohydrates into simple sugars.
These small molecules are then absorbed into the bloodstream and transported to the liver. The liver plays a key role in metabolism, detoxification, and storage of nutrients. It also produces bile, which is necessary for the digestion and absorption of fats.
The kidneys, while not part of the digestive system, play a crucial role in the excretion of waste products from the body. They filter the blood, removing waste products and excess water to form urine, which is then excreted from the body.
Finally, any undigested food passes into the large intestine, or colon, where water and electrolytes are absorbed. The remaining waste material is then excreted from the body as feces.
So, while the kidneys and liver play important roles in the body, they are not part of the digestive system. The digestive system is primarily responsible for breaking down food and absorbing nutrients.
