Transcript of The digestion process

By Pierce Clair, Mary Doheny, Jen Whittington, Jack Galvin
Once the food is in the esophagus, muscles in your throat push the food into the stomach where it will begin to break down. this process of relaxing and contracting muscles to move food is known as peristalsis
The Digestion Process
The bite of Turkey Sandwich enters the dark bowels of the mouth and begins mechanical digestion.

Then the food enters the esophagus.
The esophagus drops food into your
stomach. This process takes about
6 seconds.
The Esophagus is in the throat by the trachea. It connects the throat and stomach, and is 8 inches long , lined with a pink tissue
Cardiac Sphincter
Pyloric Sphinctor
Amylase is released from the salivary glands to break down starches from the food, into sugars. Amylase digests carbohydrates and is also produced by the pancreas. This process takes about a minute.
After the Turkey Sandwich bite gets broken down in the stomach, leftover bile will travel into the Gallbladder. The gallbladder helps absorb and digest fats. Its a pear-shaped, and has a hollow structure. It is located under the liver and on the right side of the abdomen.The rest of the chyme will squirt into the duodenum, the uppermost part of the small intestine, where the body can absorb the nutrients into the bloodstream. Digestive fluids such as trypsin, amylase, and lipase are released from the pancreas, liver, and lining of the duodenum are added to the chyme at this stage.
Once the food is in the Stomach, Pepsin is released to digest foods such as meats, eggs, seeds and dairy products. It breaks down proteins into large peptides that the body can use. It churns the food until it becomes a thick liquid known as chyme.
Most waste will travel from the intestines and into the rectum. The body needs to get rid of all the bacteria that is located in the feces, so it uses the process of elimination. The excrement will then
travel out of the anus.
(Large Intestine)
The small intestine breaks down remaining disaccharides into monosaccharides and dipeptides into amino acids. the small intestine is a 22-foot long muscular tube under the stomach.
once the food has entered the small intestine, chemicals from the liver and pancreas are released to further break down the food and take out all the nutrients. Trypsin, is a digestive enzyme that breaks down proteins in the small intestine. It is secreted by the pancreas in a inactive form, and lipase which digests fats, are released from the pancreas and added to the chyme. more chemicals are released such as Maltase, which changes sugar into starch, lactase, which digests milk sugars and is found in the lining of the small intestine, also sucrase is released to break sucrose into fructose and glucose. Small fingerlike projections in the small intestines, that are covered in microvilli, are used by the process of absorption, to absorb nutrients and transfer them into the bloodstream. Most nutrients are absorbed into the blood, but fats are absorbed into the lymph. The rest of the chyme then enters the large intestine
The liver is used process the nutrients absorbed from the small intestine. It takes the raw materials absorbed by the intestine and makes all the various chemicals the body needs to function. The liver is about the size of a football. It's located in the upper right portion of your abdomen
The Salivary Glands are located just below the tongue, above you mouth, and on the sides in your cheek's . The Salivary Glands have glands with ducts that provide saliva. This is also where amylase comes from. Chemical digestion begins when saliva is released. Maltase is present in saliva to breakdown malcose.

The tongue helps by moving around food when you're chewing. Also your tongue allows you to taste different food. It has thousands of taste buds. The tongue runs to the back of your throat. The muscles in the back of the tongue help push food to the back of the mouth and into the esophagus.
The parts of the food that could not be digested move into the large intestine. It is responsible for processing waste. The food is passed through the colon (or large intestine) by means of peristalsis, first in a liquid state and then becomes a solid. The large intestine absorbs water and vitamins that are released from the feces before storing it in the rectum to leave the body as waste. The colon is a 6-foot long muscular tube that connects the small intestine to the rectum.
The pancreas secretes digestive enzymes into the first segment of the small intestine. The enzymes break down protein, fats, and carbohydrates. It’s about 6 inches long and is located behind the stomach.
The epiglottis is located between the larynx and the esophagus. The epiglottis is a flap made of elastic cartilage tissue. It prevents the body from food getting stuck in the airway. It permits the food to pass.
The trachea is connected to a tube system which makes it possible for you to swallow. When it s blocked you start chocking.
Your trachea is connected to a tube system which makes it possible for you to swallow. When it is blocked, you start choking. Choking, combined with a coughing reflex, enables the cells to get the foreign object out of the respiratory system and trachea. Its a wide, hollow tube that connects the larynx (or voice box) to the lungs.

The stomach holds food while it is being mixed with enzymes that break down food into a usable form using strong acids and powerful enzymes in the lining of the stomach. Then its released to the small intestine. The stomach is a organ on the left side of the abdomen. It looks like a big bean.
The rectum receives waste from the colon, to let the person know that there is stool to be evacuated, and to hold the stool until evacuation happens. It is an 8-inch chamber that connects the colon to the anus
