What are the major organs of the Digestive System?
The Pancreas - This organ makes insulin which also helps metabolism inside of sugars. This organ is located behind your stomach. It helps store sugar and vertebrates. This organ has 2 systems the Exocrine, and the digestive Exocrine function.
The Salivary Glands - Made up mostly of water the salivary glands also help break down food with mucus and an enzyme called ptyalin.
The Small Intestine - Most of the absorption takes place in the small intestine which is almost 20 feet long. Villi and microvilli inside the intestines absorb the nutrients from the broken down food.
The Stomach - Your stomach is a large and very important organ in the digestive system. The stomach breaks down food you've eaten and it's fully broken down in 3 days. Enzymes and acids make sure food remains there for 8 hours.
The Tongue - Helps break down the food along with the teeth.
The Appendix - Produces and protects good germs for the gut by rebooting the digestive system.
The Esophagus - The esophagus in the Digestive system is the 1st part of it. It begins in your neck then it reaches towards your chest. Once its in your chest it leads to your stomach. Once it's in your stomach muscles lead it into your stomach acids where it's broken down.
The Gall bladder - Bile is stored and released from the gallbladder. When fatty food enters the duodenum the gallbladder contracts and releases bile.
The Large Intestine - Undigested food stays here and makes vitamins to send to the body.
The Liver - The liver produces bile for fat digestion and getting rid of fat. nutrients are stored in the liver, and toxins and chemicals are filtered by the liver.
Nervous System
The digestive system can function only when it coordinates with the nervous system, specifically the enteric nervous system.
It's made up of collagen fibers, the lamina propria, muscle tissue, smooth muscle tissue and the stomach.
It helps move things around like your heart and it makes air go into little tubes to get air in and out.
Muscle Tissue
The cardiac sphincter is a circular muscle located at the distal end of the esophagus .
The skeletal salivary amylase, which breaks down starch. Teeth, which are part of the skeletal system, play a key role in digestion.
The Smooth muscle also lines the majority of the digestive system, for similar reasons. However, the cells in the digestive system have different stimuli than those in the circulatory system.
Connective Tissues
Connective tissues fill the spaces between other tissues and form organs.
Connective tissue varies greatly but has in common the fact that they have a cellular component and an extracellular component made by the cells of the tissues.
One group of connective tissue contains the loose, dense-irregular and dense regular.
Epithelial Tissue
One of the primary functions of epithelial tissue is protection.
The epithelium is like a flexible, adaptive armor plating for the body. Simple columnar epithelial tissue lines most of the digestive tract.
New cells are constantly growing to replenish older ones, and in some cases, like the skin, a layer of keratinized cells acts as an additional layer of protection.
