The pancreas is located deep in the body behind the stomach. It is shaped like a fish and produces proteins, sodium bicarbonates, and pancreatic juices. These juices mix with bile from the liver and gallbladder and empty into the small intestines, where they neutralize stomach acids and help digest food into smaller pieces, demonstrating the important role the pancreas plays in the body's digestive functions.

Large intestine
The large intestine comes after the small intestine and measures approximately 1.5 meters. It absorbs water and nutrients from waste and protects the body from infections. The large intestine consists of the cecum, colon (ascending, transverse, descending, and sigmoid sections), rectum, and anal canal. It removes remaining water from digested food and stores waste until defecation through contractions that move waste to the rectum for elimination.
Small intestine physiology
The small intestine is responsible for the digestion and absorption of nutrients. It is made up of the duodenum, jejunum, and ileum. The small intestine contains finger-like villi covered in microvilli that increase surface area for absorption. Glands including crypts of Lieberkuhn and Brunner's glands secrete enzymes and mucus. Movement patterns in the small intestine include segmentation contractions that mix contents, peristalsis that propels contents aborally, and villi movements that enhance absorption. Disorders can impair digestion or absorption.
Urinary system
The urinary system consists of the kidneys, ureters, urinary bladder and urethra. The kidneys filter the blood to remove wastes and produce urine. The nephron is the functional unit of the kidney that filters blood and forms urine. Urine passes from the kidneys through the ureters into the bladder, and is then emptied through the urethra. Urine formation involves glomerular filtration, tubular reabsorption and secretion, and a countercurrent mechanism in the kidney. The urinary system regulates water and electrolyte balance and removes nitrogenous wastes from the body.

The pancreas
The pancreas is a soft, lobulated organ that lies transversely across the posterior abdominal wall. It has both exocrine and endocrine functions. The exocrine pancreas secretes enzymes through a duct system to aid digestion. The endocrine pancreas secretes the hormones insulin and glucagon through clusters of cells called islets of Langerhans to regulate blood sugar levels. The pancreas has a head, neck, body and tail and receives its blood supply from several arteries while its venous drainage involves the portal vein.
Anatomy of kidney
The kidneys are paired retroperitoneal organs located on the posterior abdominal wall. Each kidney has an outer renal cortex and inner renal medulla divided into renal pyramids. The kidneys receive blood supply from the renal arteries which branch into segmental and lobar arteries before branching further. Blood exits via interlobar, arcuate and interlobular veins into the renal veins which drain into the inferior vena cava. The kidneys are surrounded by fibrous capsules and perirenal fat and have anterior relations to other abdominal organs and posterior relations to the vertebral column and muscles.
HUMAN URINARY SYSTEM - Anatomy & Physiology
The urinary system consists of the kidneys, ureters, urinary bladder, and urethra. The kidneys filter waste from the blood to form urine. The urine travels from the kidneys down the ureters to the urinary bladder, where it is stored until urination. During urination, the bladder contracts and the urethra carries the urine out of the body. In addition to removing waste, the urinary system regulates fluid and electrolyte balance and blood pressure.
PPT on Gall bl;adder
The gallbladder is a pear-shaped sac located on the posterior surface of the liver that is around 7-10 cm long and 3 cm broad with a capacity of 30-50 ml. It is divided into three parts: the body, fundus, and neck. The cystic duct runs from the neck of the gallbladder to join the hepatic duct and form the common bile duct. The gallbladder stores and concentrates bile released from the liver and regulates pressure in the biliary system through contraction and dilation.

Urinary system ------(Physiology)
The urinary system removes waste from the bloodstream through the kidneys, stores it in the bladder, and excretes it from the body through the urethra. The kidneys filter waste from the blood to form urine, which travels through the ureters to the bladder. When full, the bladder contracts to expel urine through the urethra in a process called micturition. The kidneys, ureters, bladder, and urethra work together to maintain homeostasis by regulating waste removal, fluid balance, and blood pressure.
Small intestine
The small intestine is responsible for most digestion and absorption of nutrients. It is divided into three parts - the duodenum, jejunum, and ileum. The duodenum contains Brunner's glands which secrete mucus to protect the lining and help regulate pH. It connects to the bile ducts and pancreas. The jejunum and ileum further digest food and absorb nutrients through fingerlike villi before waste passes to the large intestine.

Stages & regulation of pancreatic secretion
The document discusses the phases and regulation of pancreatic secretion. It describes three phases: the cephalic phase, gastric phase, and intestinal phase. In the cephalic phase, acetylcholine causes acinar cells to secrete enzymes via parasympathetic stimulation. In the gastric phase, secretion continues in the same way. However, the enzymes from these first two phases generally are not released into the intestine until the intestinal phase. In this third phase, the hormones secretin and cholecystokinin are released in response to acidic chyme and fats in the duodenum. They work to secrete bicarbonate and digestive enzymes through the pancreatic ducts. Together, the endocrine and nervous systems regulate

Pancreas
The pancreas is a gland organ located in the abdomen that functions as both an exocrine and endocrine gland. It has a head, neck, body, and tail and produces hormones like insulin and enzymes that help break down food. The islets of Langerhans within the pancreas contain different cell types that secrete various hormones like insulin, glucagon, and somatostatin to regulate blood sugar levels. Diseases of the pancreas can develop if it is inflamed or not functioning properly, such as diabetes which occurs when insufficient insulin is produced.

Digestive enzymes
Digestion is the process of breaking down food into simpler components so that the body can absorb nutrients. This occurs through the action of digestive enzymes secreted by glands in the mouth, stomach, pancreas, and small intestine. These enzymes break down proteins, carbohydrates, and fats into their basic building blocks like amino acids, simple sugars, and fatty acids. The main sites of digestion are the oral cavity, stomach, duodenum and jejunum where different enzymes break down components of food at each location to prepare it for absorption in the small intestine.
Y7 Life 09 digestion
Digestion is the process by which food is broken down into smaller bits and nutrients are absorbed into the body. Digestion begins in the mouth through mechanical and chemical breakdown by teeth and saliva. Food then moves to the stomach through the esophagus and is further broken down by stomach acid and enzymes. Nutrients are then absorbed in the small intestine through the actions of enzymes from the pancreas and bile from the gallbladder. The large intestine absorbs water before waste is expelled through the rectum and anus.

Digestive system
The document summarizes the human digestive system. It describes how food is broken down as it passes through the mouth, esophagus, stomach, small intestine, and colon. Key steps include chewing and mixing with saliva in the mouth, peristalsis to move food through the esophagus, churning and breaking down of proteins in the acidic stomach, further breakdown of nutrients by enzymes in the small intestine, and water absorption with waste formation in the colon. The end products are then excreted from the body.
Digestive system
The digestive system is made up of the gastrointestinal tract and accessory organs. The gastrointestinal tract includes the mouth, esophagus, stomach, small intestine, large intestine, rectum and anus. Food is broken down mechanically and chemically as it passes through these organs. The accessory organs, including the liver, gallbladder and pancreas, produce enzymes and bile that aid in digestion. Nutrients are absorbed through the small intestine into the bloodstream and waste is eliminated as feces through the large intestine and anus.
Digestion
Digestion is the breakdown of large insoluble molecules into smaller soluble molecules that can pass through the gut and into the blood. Food is broken down in a multi-step process as it moves through the digestive system. In the mouth, chewing and saliva start to break down carbohydrates. Peristalsis moves the food through the esophagus to the stomach, where gastric juice contains enzymes and acid that break down proteins. The stomach releases food into the small intestine, where pancreatic juices break down lipids and bile emulsifies and neutralizes acid to aid fat digestion. Enzymes in the small intestine complete digestion of carbohydrates, proteins and lipids, and the villi in the intestines absorb the nutrients into the
Soguilon, jhomer denn
The digestive system is made up of the mouth, pharynx, esophagus, stomach, small intestine, large intestine, and accessory organs like the liver, gallbladder and pancreas. Food is broken down mechanically and chemically as it passes through these organs. The mouth breaks food into small pieces, the stomach acids break food into chyme, and the small intestine absorbs nutrients through villi before waste passes to the large intestine. Accessory organs produce enzymes and bile to further break down food.
Digestive system
Digestion is process by which complex food get converted into simpler food so as to easily get absorbed into blood stream and act as a energy source.
Digestion 2011
The document summarizes the journey of food through the digestive system. It begins with ingestion in the mouth, where teeth break down food and saliva begins digestion. Peristalsis then moves food to the stomach for mixing with acids and enzymes. Digestion continues in the small intestine where nutrients are absorbed into the bloodstream. Undigested waste then moves to the large intestine where water is absorbed before waste is expelled through the anus.
Digestive System
The digestive system breaks down food through mechanical and chemical digestion. The digestive tract includes the mouth, esophagus, stomach, small intestine, large intestine, rectum, and anus. Accessory organs that aid digestion are the liver, gallbladder and pancreas. Each organ has a specific role in further breaking down food, absorbing nutrients and eliminating waste. Mechanical digestion begins in the mouth through chewing, while the stomach, pancreas, liver and intestines secrete enzymes and acids that chemically breakdown food into smaller molecules for absorption.
The Pancreas- General overview of the Pancreas
The pancreas is a dual function organ that is approximately 15 cm in length and located posteriorly to the stomach. It has an exocrine gland that produces enzymes to aid digestion and endocrine glands that release hormones like insulin and glucagon to regulate blood sugar. The pancreas is divided into a head, neck, body, and tail and while people can live without it, they must supplement the hormones and enzymes it normally produces.

Life Science 3.1 : The Digestive System
The digestive system breaks down food into nutrients that the body can use. It includes the mouth, esophagus, stomach, small intestine, large intestine, liver, gallbladder and pancreas. Mechanical digestion breaks down food physically while chemical digestion uses enzymes to break down molecules. Digestion begins in the mouth and food travels through the esophagus to the stomach where it is further broken down. Nutrients are then absorbed in the small intestine before waste is passed into the large intestine and eliminated from the body.

The document discusses the structure and function of the digestive system. It describes the major organs involved, including the mouth, esophagus, stomach, pancreas, small intestine and large intestine. It explains that both physical and chemical digestion break down large food molecules into smaller absorbable ones. Chemical digestion involves enzymes that are produced in various glands and organs that break down carbohydrates, proteins and fats through the process of hydrolysis.
Digestive system
The digestive system breaks down food into smaller molecules that can be absorbed and used by cells in the body. Digestion begins mechanically in the mouth through chewing and continues through the esophagus and stomach with enzymes. In the small intestine, the pancreas, liver, and gallbladder further break down food as it is absorbed by the body. Undigested waste moves to the large intestine where water is absorbed before exiting through the rectum and anus. Proper care of the digestive system involves eating a balanced diet, staying hydrated, exercising, seeing a doctor if issues persist, and undergoing recommended tests.
