Digestion by A Morton https://padlet.com/abglmrtn/odc62cp79a8w en-us 2014-11-03 03:21:24 UTC 2017-05-17 11:18:25 UTC hello@padlet.com Recipe: gastric fluid abglmrtn https://padlet.com/abglmrtn/odc62cp79a8w/wish/39472651

1. Get some mucus (you can find it in the epithelial cells).

2. Add pepsinogen to help digest proteins.

3. Stir thoroughly.

4. Sprinkle in hydrochloric acid (HCL) VERY CAREFULLY!!! IT IS AN ACID!!!

5. Stir carefully. The pepsinogen should react with the HCL and turn into pepsin.

6. Mix in some Assorted Stomach Fluids (TM).

Peristalsis: rythmic squeezing movements that make sure the food goes down the esophagus

Cardiac spincter: the opening into your stomach that can open and shut like a drawstring

The third and longest step in digestion is the small intestine. If you were to strech it out your small intestine would be up to 7 meters long. Because the small intestine is so long, it is divided into sections. The first twenty five to thirty centimeters is called the duodenim. The duodenim is where most of the digestion occurs.

Your pancreas is an organ that comes into play during that phase.

When the hydrochloric acids reach your small intestine, a hormone called prosecreten is released. It then gets turned into secreten and signals the pancreas. When that happens the pancreas releases a fluid containing bicarbionate ions that gets sent to the small intestine and brings the pH level up to around 9.

What exactly does the pancrease release into the small intestine? It actually releases many things:

-tripsinogin is a protein-digesting enzyme

-enterokinase turns inactive tripsinogin into active tripsin (released by small intestine)

-erepsins are enzymes that converts small-chain peptides into amino acids

-amalayse enzymes continue to break down carbohydrates

-disaccharide enzymes called disaccharidases complete digestion of carbohydrates (released by small intestine)

-lipases are enzymes that break down lipids

The stomach has many ways to break down food. One way it does that is by contracting and churning all the pieces of food.

The stomach also releases an enzyme called pepsin which helps to digest proteins.

Another fluid that is used in the stomach for digestion is called gastric fluid. Gastric fluid contains Hydrochloric Acid which has a pH level of 2-3, so that breaks down food as well. Don't worry though, alkaline mucus stops the stomach walls

from being digested as well.

food goes down the esophagus with help from squeezing

movements called peristalsis, through the cardiac spincter

and into your stomach.

-tonsils are often crowded in the back of your mouth and have to be removed (Dad, Oct. 30 2014)

The first part of digestion is your mouth. Your mouth breaks down the food in two ways.

First of all, teeth crunch and munch the food into smaller peaces. Different teeth do different things. Your incisors are great at cutting, and getting smaller chuncks of food in your mouth than if you just shoved a whole apple in. Your canines are good at tearing. Your molars do a fine job of crunching and grinding, and your wisdom teeth don't really do anything except help the moalers.

The other thing in your mouth that breaks down your food is saliva. Saliva contains an enzyme called amylase that breaks down complex carbohydrates (starches).
