The Digestive system is one of the many systems our bodies possess. The digestive system is mainly the system that breaks down the food we eat into energy and produces the waste that leaves our body. The digestive system is made up of the digestive tract, a series of organs joined in a long twisting tube from the mouth to the anus. Also, made of other organs, that helps break down the food. The digestive System is made up of a lot of organs, but the main ones consist of the esophagus, stomach, small intestine, large intestine and the rectum or anus. What happens is when you eat food it goes down to your stomach through your esophagus. Then, once that happens your stomach uses chemicals such as gastric juices that include hydrochloric acid and enzymes. Which helps break down the food into a liquid called chyme, the stomach now passes the food to the liver, or gallbladder. The gallbladder then breaks down our food with bile. This is important because it breaks down the fats that will supply us with a lot of energy later. After the gallbladder is the pancreas which just adds more chemicals to breaking down our food. Following the pancreas we meet the hero of the digestive system the small intestine. The small intestine is a tube that is 22 feet long that uses more chemicals but crushes our food even more where it is ready to be used by the body. After the small intestine is the large intestine which is where the parts of food our body doesn’t use goes. The main job of…

CH. 24 Digestive System-
1. Alimentary Canal: from mouth to anus about 29-30 ft. long
2. 6 main organs of digestion:
e. small intestine
f. large intestine
3. 7 accessory organs of digestion:
h. salivary glands
4. 4 coats of digestive tract:
into the Eustachian tubes, which connect the pharynx to the ear. The digestive system consists of the organs of the digestive tract, or food tube, and the digestive glands. From the esophagus, swallowed food moves into the stomach and then into the small intestine. Bile is a digestive juice made by the liver and stored in the gallbladder. Bile flows into a tube called the common bile duct, into which pancreatic juice, a digestive juice from the pancreas, also flows. The contents of the common bile…
breaking protein down into individual amino acids is pepsin. The hydrochloric acid converts the inactive form to an active form. Most of the protein digestion takes place in the small intestine. The pancreas is what secretes the enzymes into the digestive tract in order to further break down the protein strands into peptide chains of many amino acids. One type of enzyme that digests proteins is protease enzymes. There are different types of these enzymes and they include pepsin which is an enzyme…

A process by which a parent cell divides into two or more daughter cells is called cell division. Cell division is a small part of the cell cycle. In normal eukaryotic cells the type of cell division is known as mitosis. Another type of cell division is present in reproductive cells of eukaryotes known as meiosis. Cell cycle is mainly classified into two segments: M-phase and Interphase. Interphase is the longer period of cell division. During this phase the cell…

Hormone regulation is the role of the hormones involving the digestive tract. The three main hormones are CCK, gastrin and secretin (NIH, 2008, pp.1). These hormones are released in to the blood stream surrounding the digestive tract to then circulate through the heart and back to the digestive area in which they are then able to stimulate the digestive juices resulting in movement of various organs (NIH, 2008, pp.1). Gastrin is produced by the stomach and…

Identify the anatomy of the digestive system
Digestion is the process which turns food which is consumed into the energy needed to survive. The digestion process also involves creating waste to be eliminated.
The digestive tract is a long winding tube that begins in the mouth and ends at the anus. It is made up of a series of muscles that coordinate the movement of food and other…
Crohns disease is a disease affecting the digestive system. It was named after Dr. Burrill B. Crohn who first describe the disease the 1932 along with some other colleages. Crohns disease belongs to a group of disease known as inflammatory bowel diseases or IBD for short. Crohns disease is a chronic inflammatory condition of the gastrointestinal tract. Crohns disease most commonly affects the end of the small bowel and the beginning of the colon but can also infect the gastrointestinal…
The Digestive System
Digestion helps food break down into nutrients, which the body uses for energy, growth, and cell repair. The nutrients are broken down into carbohydrates, proteins, fats, and vitamins. The organs that break down the food are the mouth, esophagus, stomach, small intestine, pancreas, and liver. The digestion process is controlled with hormone and nerve regulators.
Nutrients are broken down into four different things. They are broken down into carbohydrates, proteins…
Your digestive system gears up
A fresh-baked apple pie has just come out of the oven. Just the sight and smell of it are enough to make you start salivating. So even before you take a bite, your digestive system has swung into action.
After the first morsel enters your mouth, the many organs of your digestive tract kick into high gear. Here's a look at how your digestive system works, from top to bottom.
Mouth and salivary glands
After you take your first bite of pie, your salivary…
