Buccal Cavity Research Paper
The buccal cavity is the portion of the oral cavity bounded by the lips, cheeks, and gums. Also called vestibule of mouth. This plays an important role in speech, taste and the first steps of digestion.
The oesophagus is a hollow muscular tube that transports saliva, liquids, and foods from the mouth to the stomach. The muscular layers that form the oesophagus are closed tightly at both ends by sphincter muscles, to prevent food or liquids from leaking from the stomach back into the oesophagus or mouth.
The main function of the stomach is to break down and digest food in order to extract necessary nutrients from what you have eaten. In order for this to happen, it is necessary that the stomach, the digestive glands and the intestines must …show more content…
It receives partially digested food (known as chyme) from the stomach and plays a vital role in the chemical digestion of chyme in preparation for absorption in the small intestine.
The pancreas is a glandular organ in the upper abdomen, really it serves as two glands in one: a digestive exocrine gland and a hormone-producing endocrine gland. Functioning as an exocrine gland, the pancreas excretes enzymes to break down the proteins, lipids, carbohydrates, and nucleic acids in food.
The liver is responsible for producing enzymes and solutions necessary for digestion. This includes the production of bile, which helps with the breakdown of fat from our food
The gallbladder is a hollow structure located under the liver and on the right side of the abdomen. Its main function is to store and distillate bile, a yellow-brown digestive enzyme produced by the liver. The gallbladder is part of the biliary tract. The gallbladder serves as a basin for bile while it’s not being used for …show more content…
The glands in the stomach lining produce stomach acid, called gastric acid, and an enzyme that digests protein. The pancreas produces a juice containing several enzymes that break down carbohydrates, fats, and proteins in food. The pancreas delivers digestive juice to the small intestine through small tubes called ducts.
Function Of Digestive System
Digestion is the breakdown of large insoluble food molecules into small water-soluble food molecules so that they can be absorbed into the watery blood plasma. In certain organisms, these smaller substances are absorbed through the small intestine into the blood stream.
During the process of absorption, nutrients that come from the food, including carbohydrates, proteins, fats, vitamins, and minerals, pass through channels in the intestinal wall and into the bloodstream. The blood works to distribute these nutrients to the rest of the body.
The final function of the digestive system is the excretion of waste in a process known as defecation. Defecation removes indigestible substances from the body so that they do not accumulate inside the
