Pancreatic islets are regions of the pancreas with specialized cells, such as beta and alpha cells. They produce insulin and glucagon, regulating blood glucose levels and maintaining metabolic balance.
Pancreatic physiology combines digestive and endocrine functions. The pancreas produces enzymes that break down food and hormones like insulin and glucagon that regulate blood glucose levels.
Small intestine villus hair refers to microvilli on enterocytes that increase the absorption surface. They enable efficient nutrient uptake from digested chyme in the digestive system.
The stomach sections include cardia, fundus, body, antrum, and pylorus. Each region plays a key role in digestion, food storage, mixing, and controlling the passage of food into the small intestine.
The small intestine structure includes the duodenum, jejunum, and ileum. Its mucosa has villi and microvilli that increase the absorption surface and allow efficient nutrient uptake in the digestive system.
The anatomy of the livershows a vital organ located on the right side of the abdomen. It is divided into hepatic lobesand made of hepatocytes, which perform metabolic, digestive, and detoxification functions.
The anatomy of the stomachshows a sac-shaped organ located in the upper abdomen. It is divided into the cardia, fundus, body, and pylorus, which participate in the digestion of food.
The blood supply of the stomachcomes mainly from the celiac trunk, through arteries such as the left and right gastric arteries, which provide oxygen and nutrients to stomach tissues.
The cross-sectionof the stomachshows the layers: mucosa, submucosa, muscularis, and serosa. The gastric mucosaproduces enzymes and gastric acid that begin food digestion.
The digestive system is a group of organs that break down food into absorbable nutrients. It includes the mouth, stomach, intestines, liver, and pancreas, ensuring digestion and efficient nutrient absorption.
The layers of the gastrointestinal tract include the mucosa, submucosa, muscularis, and serosa. The mucosa produces enzymes and absorbs nutrients, while the submucosa contains blood vessels and nerves.
The layers of the stomachinclude the mucosa, submucosa, muscularis, and serosa. The gastric mucosaproduces acid and digestive enzymes, while the muscular layers mix food during digestion.
