Digestive system
Today I would like to begin my paper with a quote from a very intelligent person, in my opinion. The quote is stated in a Checkers commercial and goes like this "you gotta eat". The words are very simple and very true. The process of eating, digesting, and getting rid of the food that we consume is what interest's me the most and very important in life and survival. That is why I've decided to write on the digestive system today. In this paper I will be discussing the function's of the digestive system and the path food takes entering your body and exiting your body. First, I wanted to give you a overview on the very start of the digestive system and some of it functions as well. At the very beginning of this process is where ingestion occurs. This is where the actual food comes into the mouth. Once the food is in the mouth, the teeth cut and breakdown food working with the tongue to shape it into a round mass for swallowing. The salivary glands also play an important role in the ingestion process. They produce a saliva that lubricates , dissolves, and starts the chemical breakdown of food. Next I wanted to take you down the path of the pharynx and esophagus. The pharynx is not a majo
The stomach receives the food and then gets macerated by mixing waves. It arrives at the large intestine and any nutrients not absorbed in the small intestines is done here. The pancreatic juice is slightly alkaline (basic) and buffer acidic gastric juices in chyme. The pancreas secretes a pancreatic juice which is a mixture of fluid and digestive enzymes. Then, after leaving the pharynx and esophagus it arrives at the stomach followed by the pancreas. Two very vital organs in this system. The liver also produces a thick, green liquid, other wise known as bile. The small intestines is where absorption begins to take place. Haustral churning, peristalsis, and mass peristalsis drive the rest of the contents of the colon into the rectum. Finally, we arrive at two very essential organs in the digestive system. One more important function of the liver is that it helps aid in the activation of vitamin D. The food is then moved through by a process known as peristalsis, which is a progression of coordinated contractions and relaxations of circular and longitudinal layers of the muscular is. Two very important organs that aid in this process. It mixes with secretions of gastric juice and gets reduced down to chyme, which is a semi-fluid mixture of food.
