Digestive system By: Jordyn hall

mouth Your mouth is one of the most important parts of your body and if Anything happened to your mouth it can make it hard to eat, drink or even smile every day.

Esophagus  A esophagus is a muscular tube connecting to the throat and with the stomach. The esophagus is about 8 inches long,. The esophagus runs behind the windpipe,the heart, and in front of the spine.

Stomach The stomach is part of the digestion system which functions as an important organ of the digestive tract. The stomach is located between the esophagus and the small intestine.

small intestines The small intestines is part of the gastrointestinal tract following the stomach and the large intestines.

Large intestine  The colon is a tubular structure that is around 1.5 m, about one quarter of the length of the small bowel. Its largest diameter is at the cecum (7.5 cm) and narrowest in the sigmoid (2.5 cm).

Liver The liver holds about one pint (13 percent) of the body's blood supply at any given moment. The liver consists of two main lobes, both of which are made up of thousands of lobules. These lobules are connected to small ducts that connect with larger ducts to ultimately form the hepatic duct. The hepatic duct transports the bile produced by the liver cells to the gallbladder and duodenum (the first part of the small intestine).

Appendix  The appendix sits at the junction of the small intestine and large intestine. It’s a thin tube about four inches long. Normally, the appendix sits in the lower right abdomen.  The function of the appendix is unknown. One theory is that the appendix acts as a storehouse for good bacteria,

Pancreas  The pancreas is a gland organ in the digestive and endocrine system of vertebrates. It is both an endocrine gland producing several important hormones, including insulin, glucagon, and somatostatin, as well as an exocrine gland, secreting pancreatic juice containing digestive enzymes that pass to the small intestine. These enzymes help in the further breakdown of the carbohydrates, protein, and fat in the chyme.

Gall bladder  The gallbladder is a small pouch that sits just under the liver. The gallbladder stores bile produced by the liver. After meals, the gallbladder is empty and flat, like a deflated balloon. Before a meal, the gallbladder may be full of bile and about the size of a small pear.

Enzymes  It may surprise you that there isn't just one enzyme or molecule that breaks down all the food we eat. In fact, the process of digestion, or the breaking down of large pieces of food, is complex and involves several enzymes, each with a specific function. Let's look at the range of enzymes in our digestive system and find out how each one functions to keep us healthy by allowing big pieces of food to become small absorbable molecules.

Bile/bile duct  Bile is a liquid released by the liver. It contains cholesterol, bile salts, and waste products such as bilirubin. Bile salts help your body break down (digest) fats. Bile passes out of the liver through the bile ducts and is stored in the gallbladder. After a meal, it is released into the small intestine.  When the bile ducts become blocked, bile builds up in the liver, and jaundice (yellow color of the skin) develops due to the increasing levels of bilirubin in the blood.

Mucus  Mucous fluid is typically produced from mucous cells found in mucous glands. Mucous cells secrete products that are rich in glycopr Mucous fluid is typically produced from mucous cells found in mucous glands.

Chemical digestion  Process of dissolving and chemically converting food for absorption by cells. In the mouth, food is chewed, mixed with saliva, which begins to break down starches, and kneaded by the tongue into a ball for swallowing. Peristalsis propels it through the esophagus and the rest of the alimentary canal. In the stomach, food mixes with acid and enzymes, which further break it down. The mixture, called chyme, enters the duodenum, the first part of the small intestine. Bile from the liver breaks up fat globules. Enzymes from the pancreas and intestinal glands act on specific molecules, breaking carbohydrates down into simple sugars, proteins into amino acids, and fats into glycerol and fatty acids. These products are absorbed by the bloodstream.

Absorption . Absorption is occurs largely in the small intestine, which has developed a large surface area for this purpose. . Absorption is occurs largely in the small intestine, which has developed a large surface area for this purpose. The walls of the small intestine contain numerous. The walls of the small intestine contain numerous finger-like projections called villi,

Mechanical digestion  Mechanical digestion breaks down food into smaller particles so that it can be easily be processed by the digestive

Salivary amylase  Salivary amylase breaks down starch into sugars, such as rice and potato, taste slightly sweet as they are chewed because amylase turns some of their starch into sugar in the mouth.

villi  The large intestine takes about 16 hours to finish the digestion of the food. It removes water and any remaining absorbable nutrients from the food before sending the indigestible to the Rectum.

Gastric juices  Gastric juices are liquids in your stomach which break down food so that nutrients can be extracted by your intestines.

Duodenum  We have salivary amylase in our mouths so that carbohydrates begin digestion in the mouth.

Chyme  The chyme is particles of foods that become small enough, and into the small intestine, which stimulates the pancreas to release fluid.. Other secretions from your body like your pancreas, gallbladder, liver, and glands in the intestinal wall help in digestion.
