How the food changes consistency and form
From the video, we can observe how food changes in the following ways:
It begins as regular food. Through the mouth, it is put through chewing and hydrolysis where the food will turn into bolus. It is then swallowed and then passed on to the esophagus and then to the stomach. The food is churned and undergoes hydrolysis again. The bolus melts down into chyme which will then go through our intestines. The small intestine absorbs nutrients from the food and then goes through the large intestine. The rectum stores the processed food and is held there until it is expelled. When it leaves the body, it will come through the anus as feces.
2. How the body was able to absorb the nutrients from the foods we eat. T
Food is churned and undergoes hydrolysis in the stomach. You can store food in your stomach. In the small intestine, hydrolysis and the absorption of nutrients occurs. Here, you take the food products and use them for nutrition to make other products in your body. In the large intestine, you can absorb things like water, ions, and vitamin K.
