2 MAJOR CLASSIFICATIONS OF THE DIGESTIVE SYSTEM
A. FOOD TUBE/ALIMENTARY CANAL/DIGESTIVE TRACT
-Mouth Cavity
-Pharynx
-Esophagus
-Stomach
-Small intestines
-Large Intestines
-Rectum
-Anus
B. ACCESSORY ORGANS/GLANDS
-Salivary glands
-Liver
-Pancreas
-Gall bladder
-Appendix
DIGESTIVE SYSTEM- responsible for the breaking down of food into simpler molecules.
ABSORPTION- bringing food to the body cells
DIGESTION-) the process of breaking down complicated chemicals in nutrients into forms that the body can use.
ETYMOLOGY: Comes from the LATIN word DIGESTUS meanng to assimilate food.
OTHER NAMES FOR THE SYSTEM:
>gastrointestinal system
>alimentary system
DISEASE: Hemmoroid-also known as "almoranas" in Tagalog.
TERMS:
Salivary Amylase-enzyme secreted by the salivary gland
Gullet-technical term for esophagus
Stomach-temporary reservoir for partially digested food (the partially digested food is technically known as the bolus or chyme)
Colon-technical term for the large intestine
SMOOTH MUSCLES:
Cardiac Sphincter and Pyloric Sphincter-they BOTH prevent the flowback of the food but each one of them performs a very important function. (Their functions can be seen in the Biology Textbook)
2 PHASES OF DIGESTION:
CHEMICAL PHASE AND MECHANICAL PHASE OF DIGESTION under the MECHANICAL PHASE OF DIGESTION: we have Swallowing and chewing under the CHEMICAL PHASE OF DIGESTION: please refer to your Biology textbook
*EGESTION(hndi ko lng sure kung ENGESTION or EGESTION s spelling)-opposite of ingestion, Egestion is the discharge or expulsion of undigested material (food) from a cell in case of unicellular organisms, and from the digestive tract via the anus in case of multicellular organisms.
It should not be confused with excretion, which is getting rid of waste formed from the chemical reaction of the body, such as in urine, sweat, etc
*Liver is the largest gland in the body

    The gastrointestinal tract starts with the mouth, which leads to the gullet via the stomach, small intestine, large intestine, and ends at the anus. In due course of the journey, the ingested food is broken down by both physical and chemical means to release nutrients which are absorbed into the blood stream. The ingested food is physically broken down in the mouth by chewing so as to reduce its size for increased surface area over which enzymatic reaction will take place. Enzymatic reaction is known as digestion and this is defined as the chemical breakdown of the ingested complex food molecules by the action of biological enzymes, into simplest form that can be absorbed into the blood stream and assimilated into living cells. In human beings, various components of the ingested food are digested and absorbed at various sections of the alimentary canal .…

    The process of digestion has many stages with the first starting in the oral cavity. Within the system, food passes through a tube called the alimentary canal, more commonly known as the gastrointestinal tract. The tract is made up of the oral cavity, pharynx, oesophagus, stomach, small intestines, and large intestines. To provide energy and nutrients to the body, major functions take place in the digestive system which include; ingestion, secretion, mixing and movement, digestion, absorption and excretion.…

    every part of the gastrointestinal tract is designed to help in the digestive process in a specific way. The mouth is involved in chewing also know as masticating. The purpose is to break down food into small enough pieces to pass through the esophagus and enter the stomach. The food is moistened with saliva helping turning it into bolus in order to turn initiate the digestion of food. The esophagus is a tube like muscle which use contractions to pass food from the mouth into the stomach it does not help with the digestive or absorptive function. The stomach acts like a sort of storage depot for food, but also acts as a place in which mechanical and chemical breakdown of food happens. The small intestine absorbs water, electrolytes, proteins, fats and carbohydrates. Whereas the large intestine is where the food matter and water that can’t be absorbed is the formed into stools. The rectum is a temporary storage area for feces before passed.…

    Once I have taken a bite out of my delicious favorite meal, the digestive system gets to work. It all begins in the mouth, chewing the food small enough to swallow. Salvia is squirted into the food to moisten and soften the food. Salvia contains enzymes, which break down the starches in food. Once the tongue forms the food into a ball to be swallowed, it is sent down the pharynx. The pharynx contains sphincters that help keep your food down once you swallow. Next, it makes its way to the esophagus, which is simply a transportation tube from the mouth to the stomach. It then reaches the stomach, which uses chemicals to make the food particles tinier. These chemicals are called gastric juices and include hydrochloric acid and enzymes. Once the stomach mixes with the chemicals, it is formed into a cream-like liquid called chyme. The gallbladder takes over from here hitting the food with more chemicals, one of them called bile. Bile is mixed with our food breaking down the fat into droplets, which will supply us with energy later on. From there, the pancreas uses digestive juice to break down…
