digestive system quizlet anatomy and physiology

It secretes protein-digesting enzymes and strong acids to aid in food digestion, (sent to it via oesophageal peristalsis) through smooth muscular contortions (called segmentation) before sending partially digested food (chyme) to the small intestines. It branches from the celiac artery, and follows a course superior to the pancreas. Mometrix. a large, reddish-brown, glandular organ located in the upper right side of the abdominal cavity, divided by fissures into five lobes and functioning in the secretion of bile and various metabolic processes. Search for: Introduction to the Digestive System. Play as. a yellow to orange bile pigment produced by the breakdown of heme and reduction of biliverdin; it normally circulates in plasma and is taken up by liver cells and conjugated to form bilirubin diglucuronide, the water-soluble pigment excreted in the bile. In most individuals, the hepatic portal vein is formed by the union of the superior mesenteric vein and the splenic vein. It is both an endocrine gland producing several important hormones, including insulin, glucagon, and somatostatin, as well as a digestive organ, secreting pancreatic juice containing digestive enzymes that assist the absorption of nutrients and the digestion in the small intestine. The glory of the digestive system exists, in part, because of the many different functions it carries out. The vitamins include vitamin D, vitamin E, vitamin A, and vitamin K, or the fat-soluble vitamins, and folate (folic acid), vitamin B12, biotin, vitamin B6, niacin, thiamin, riboflavin, pantothenic acid, and vitamin C (ascorbic acid), or the water-soluble vitamins. The gallbladder is a hollow system that sits just beneath the liver, and is divided into three sections: fundus, body and neck. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Anatomy and Physiology II. It is both an endocrine gland producing several important hormones, including insulin, glucagon, and somatostatin, as well as a digestive organ, secreting pancreatic juice containing digestive enzymes that assist the absorption of nutrients and the digestion in the small intestine. Teach Yourself Biology Visually in 24 Hours - by Dr. Wayne Huang and his team. This sphincter is so strong and folds over so much in horses and rabbits that they are unable to regurgitate or vomit. The easiest way to understand the digestive system is to divide its organs into two main categories. The system extends from about the lower portion of the esophagus to the upper part of the anal canal. A section of the stomach where the contents of the esophagus empty into the stomach. These structures correspond to the embryonic foregut. Resources : In this section we've added a few alternative study aids to help you along. It is accomplished mainly by bile acids in the small intestine. At this point it is continuous with the midgut. The pancreas is a glandular organ in the digestive system and endocrine system of vertebrates. If you're behind a web filter, please make sure that the domains *.kastatic.org and *.kasandbox.org are unblocked. Start studying Anatomy & Physiology- Digestive System Vocabulary. The duodenum is the shortest segment of the intestine and is about 23 to 28 cm (9 to 11 inches) long. It is through these villi that the digested food passes into the blood. Start studying Anatomy and Physiology 2 digestive system. Sequential Easy First Hard First. Search. A section of the stomach the lower section of the organ that facilitates emptying the contents into the small intestine. a blood vessel that drains blood from the large intestine. The series includes High School Biology, AP Biology, SAT Biology, College Biology, Microbiology, Human Anatomy and Physiology, and Genetics. Substances absorbed in the small intestine travel first to the liver for processing before continuing to the heart. B. Mastication Mastication or chewing breaks food down into smaller pieces by combining it with saliva. Learn basics of the digestive system, with a particular emphasis on liver physiology. fat-splitting enzyme; any enzyme that catalyzes the splitting of fats into glycerol and fatty acids. Human Anatomy and Physiology - Nervous System. Only $2.99/month. Quiz Digestive System. a short blood vessel that supplies oxygenated blood to the liver, pylorus (a part of the stomach), duodenum (a part of the small intestine) and pancreas. a gland organ in the digestive and endocrine system of vertebrates. As part of the initial process of food digestion, the enzymes in the saliva break down some of the starch and fat in the food at the molecular level. numerous small vessels derived from the splenic artery as it runs behind the upper border of the pancreas, supplying its body and tail. It joins with the superior mesenteric vein, to form the hepatic portal vein and follows a course superior to the pancreas, alongside of the similarly named artery, the splenic artery. This ligament is an important anatomical landmark of the duodenojejunal junction. As you have seen before, the structure of the different organs will vary according to their functions. It collects branches from the stomach and pancreas and most notably from the large intestine, which is drained by the inferior mesenteric vein and joins with splenic vein shortly before it forms the portal vein. High-density lipoproteins are one of the five major groups of lipoproteins. the anterior part of the alimentary canal, from the mouth to the duodenum at the entrance of the bile duct. Branches also supply the lower esophagus. The hepatic artery proper gives off a small supraduodenal artery to the duodenal bulb. Emulsification is the first preparation of fat for chemical digestion by specific enzymes. Links. Vitamins are organic components in food that are needed in very small amounts for growth and for maintaining good health. The processes of digestion include six activities: ingestion, propulsion, mechanical or physical digestion, chemical digestion, absorption, and defecation. Describe the types of movements that occur in the digestive system. responsible for directing blood from parts of the gastrointestinal tract to the liver. Articles - Here you'll find a range of short articles on basic anatomy and physiology topics, complete with a few 'test yourself' questions for each one. arises from the celiac artery, and runs along the superior portion of the lesser curvature of the stomach. A major component of the hepatic portal system, it originates behind the neck of the pancreas. For this reason, the hepatic portal vein is occasionally called the splenic-mesenteric confluence. the second (descending) part of the duodenum begins at the superior duodenal flexure. (Note that it is located in the foregut region, but is not a gut organ). the third (inferior/horizontal) part of the duodenum begins at the inferior duodenal flexure. Waves of muscular contraction known as peristalsis in the walls of the colon move fecal matter through the digestive tract towards the rectum. Create.
