P5: explain the role and location of organs involved in digestion
Gallbladder:
• The purpose of a gallbladder is to store bile which is needed for the digestion of fats in food. Made by the liver bile flows into the larger hepatic ducts and goes into the gallbladder where it is stored and can be used by the body later
• Your pancreas is one of the organs that secretes enzymes into the duodenum. The enzymes found in pancreatic juice break down all of the major nutrients, including carbohydrates, proteins and fats. However, the pancreas needs a little help from the liver and gallbladder when it comes to breaking down fats
Liver:
• The liver is one of the organs that break down old blood cells. The liver cells break down fats and produce energy. …show more content…
Embedded in the pancreas are the islets of Langerhans, which secrete into the blood the insulin and glucagon
• Enzymes, or digestive juices, are secreted by the pancreas into the small intestine. There, it continues breaking down food that has left stomach. The pancreas also produces the hormone insulin and secretes it into the bloodstream, where it regulates the body’s glucose or sugar level
Mouth:
• the mouth is the first portion of the alimentary canal that receives food and produces saliva. The oral mucosa is the mucous membrane epithelium lining the inside of the mouth.
• Mechanical digestion begins in the mouth as the food is chewed. Chemical digestion involves breaking down the food into simpler nutrients that can be used by the cells. Chemical digestion begins in the mouth when food mixes with saliva. Saliva contains an enzyme that begins the breakdown of carbohydrates.
Pharynx:
• Also called the throat, the pharynx is the portion of the digestive tract that receives the food from your mouth. Branching off the pharynx is the oesophagus, which carries food to the stomach, and the trachea or windpipe, which carries air to the …show more content…
• The stomach secretes acid and enzymes that digest food. Ridges of muscle tissue called reggae line the stomach. The stomach muscles contract periodically, churning food to enhance digestion. The pyloric sphincter is a muscular valve that opens to allow food to pass from the stomach to the small intestine.
Small intestine:
• The small intestine or small bowel is the part of the gastrointestinal tract between the stomach and the large intestine, and is where most of the end absorption of food takes place. The small intestine has three parts duodenum, jejunum, and ileum.
• Functions of the small intestine. The small intestine is the part of the intestines where 90% of the digestion and absorption of food occurs, the other 10% taking place in the stomach and large intestine. The main function of the small intestine is absorption of nutrients and minerals from food.
Large intestine:
• The large intestine, also known as the large bowel or colon, is the last part of the gastrointestinal tract and of the digestive system in vertebrates. Water is absorbed here and the remaining waste material is stored as feces before being removed by
