Digestive System

By Colin Gaebler

Digestive System

Food is entered through the mouth and waste is eliminated from the other end. Your saliva helps in the process of digestion so you don’t choke on the food you eat. At the end of the esophagus there is a muscular valve, where the food that you eat enters your stomach. Peristalsis in the stomach mixes the food, and mixes it with mucus and gastric juices. From the time when food is eaten it can take between 30 and 40 hours to travel the entire length of the digestive tract.

Gall Bladder

The gall bladder is a small muscular sac that acts like a reservoir for bile, which is a substance that is made by the liver. Whenever there is some fatty food is released in the intestine that came from the stomach the gall bladder releases bile to go deal with it. The bile that the gall bladder releases is also known as gall. That is how the gall bladder got its name.

Tissues and Cells

The gall bladder contains smooth muscle cells. The gall bladder also contain connective tissue.

Diseases for the Digestive System

Cholecystitis- is when your gall bladder becomes inflamed. There are two types, acute cholecystitis, and chronic cholecystitis. Gall Stones- are small rock-like stones that can form in your gall bladder. Causes- They are caused when your bile eventually gels which leads to it hardening and turning into a gall stone. Symptoms- You will feel pain in your upper right side. It will come after you eat and can be sharp and quick or a long ache. Yellow eyes, a full stomach, fever, nausea, and vomiting. Treatments- The most common way is just to remove your gall bladder because you don’t need it to live. Choledocholithias- This when a gall stone gets plugged in the neck of the gall bladder so bile can’t come out. Acalculous Gall Bladder Disease- When your gall bladder valve or muscles aren’t working properly.

Could someone live without a digestive system???

No, because you wouldn't get the nutrients you need.


Certain bones in the skeletal system are involved in chewing just like the digestive system. Certain bones in the muscular system also is very important in swallowing food. The endocrine system interacts because there are hormones that play a role in the digestive process. Also the nervous system can play a role in digestion.
