1. How the food changes consistency and form
- The mouth is the first part of the body to receive food when eating. Chewing further reduces the size of these to more manageable chunks. Hydrolysis occurs to form a bolus that is readily ingested and to aid in the process of breakdown. When swallowed, it first makes its way down the esophagus and enters the stomach. Once the bolus has entered the stomach, it will be subjected to churning and hydrolysis to be broken down into smaller pieces. This will allow the bolus to be digested more quickly. Chyme would be formed due to the churning that takes place, which would then be transported to the small intestine for further digestion. Once the food reached the small intestine, the hydrolysis process would start again. At this point, our bodies begin absorbing nutrients, which are then put to use in the production of a variety of different goods. After that, it travels into the colon or the large intestine, where water, ions, or vitamins are taken. When it is eventually time to get rid of the food, it does so through the anus in the form of excrement.
2. How the body was able to absorb the nutrients from the foods we eat
- The small intestine is where most of the digestion and absorption of the nutrients in the meals we eat takes place. These nutrients include carbohydrates, lipids, minerals, proteins, and vitamins. After that, it travels all the way through our bodies, where it is either stored or utilized. While on the other hand, the large intestine is also responsible for the process of nutritional absorption. This stage is only responsible for the absorption of water, ions, and vitamins.
