Human Body Systems Mini Project Description
In this project we were given the opportunity to learn about the anatomy and physiology of the human body and to be able to compare and contrast them to marine species. While being able to determine how many different systems of the human body are related or function together.
The Human Digestive System
Your digestive system allows you to gain nutrients and energy it needs from the food you eat. This system works before you even take a bite out of your food and It will continue working on your chewed food for a couple of hours or even a couple of days, depending on what you ate. The system begins by having saliva form in your mouth when you see, smell or even think of food.
Once you had eaten the saliva breaks down the chemicals in the food which makes it easier to swallow. Your tongue helps to push the food, piece by piece down your esophagus. The esophagus moves food from the back of your throat to your stomach. Instead of having the food go straight to you stomach, the muscles in the esophagus walls move in a wave way, it slowly squeezes the food into the stomach.The stomach breaks what came from the esophagus into even smaller pieces with the help of the muscles in the stomach walls and the gastric juice that also came from the stomach walls. Gastric juice also helps to kill the bacteria in the food. Your stomach is in charge of three things, it stores the food you had eaten, it breaks it down into a liquid and it slowly releases that liquid to the smaller intestine. The small intestine with the help of the pancreas, liver and gallbladder breaks it down even more so your body can absorb all of its nutrients and vitamins. Those organs together send juices to the top of the smaller intestine that helps the body digest the food and take in all of the nutrients. Juices from the Pancreas help digest fats and proteins, A juice from the liver called bile helps to absorb fats into the bloodstream. Your liver also filters out any harmful waste, turning some of it into bile and determines how much of the nutrients are going to go through the body and how much is going to be stored for later. The gallbladder serves as a warehouse for bile, storing it until the body needs it.Your food may spend as long as 4 hours in the small intestine and becomes a very thin, watery mixture. The leftover waste of food that your body can't use goes into the large intestine. The waste then travels to part of the large intestine called the colon, then that is your body's last chance to absorb any minerals or water into the blood. As the water leaves the waste it becomes a solid as it’s moving along. The large intestine then pushes it into the rectem and once it is ready to leave your body the rectem then pushes it out of your anus.
