Duodenum Anatomy - 1/6 (Introduction & Parts)

#Duodenum #duodenumanatomy #edulesaon #duodenumrelations The duodenum is the first part of the small intestine. Located inferior to the stomach, the duodenum is a 10-12 inch (25-30 cm) long C-shaped, hollow tube. The duodenum is a part of the gastrointestinal (GI) tract, attached to the pyloric sphincter of the stomach on its superior end and to the jejunum of the small intestine on its inferior end. After foods mix with stomach acid, they move into the duodenum, where they mix with bile from the gallbladder and digestive juices from the pancreas. The absorption of vitamins, minerals, and other nutrients begins in the duodenum. Location: - 25-30 cm long, C-shaped around the head of the pancreas, L1-L3 level Sections: - Superior (superior duodenal flexure) descending (inferior duodenal flexure) horizontal (aorta - inferior vena cava) asceding (duodenojejunal flexure) Blood supply: - Superior (anterior, posterior) and inferior pancreaticoduodenal arteries Innervation: - Celiac plexus, vagus nerve Characteristic feature: - Brunner's glands Functions: - Neutralization of the acidic gastric juice, mechanical digestion of chyme, mixing of bile and pancreatic enzymes, absorption of water, electrolytes, and nutrients The duodenum is the initial C-shaped segment of the small intestine and is a continuation of the pylorus. Distally, it is in continuation with the jejunum and ileum, with the proximal segment being the shortest and widest. Positioned inferiorly to the stomach, the duodenum is approximately 25 to 30 cm long. Interestingly enough, this portion of the small intestine got its name due to its length. In Latin, the term "duodenum" means 12 fingers, which is roughly the length of the duodenum. The 4 segments of the duodenum include the following: 1. The superior part lies intraperitoneally and is enlarged proximally (duodenal bulb). The duodenal bulb, which connects to the undersurface of the liver via the hepatoduodenal ligament, which contains the portal vein, the hepatic artery, and common bile duct. 2. The descending part and the rest of the duodenum lie retroperitoneally. The second or descending segment is just above the inferior vena cava and right kidney, with the head of the pancreas lying in a C-shaped concavity. 3. The third segment (The horizontal part) runs from right to left in front of the aorta and inferior vena cava, with the superior mesenteric vessels in front of it. 4. The fourth segment (The ascending part) continues as the jejunum (cranially along the left side of the vertebral column). This last part of the duodenum joins the intraperitoneally lying jejunum at the duodenojejunal flexure. #duodenum #pancreas #liver #medicine #anatomy #digestion #doctor #stomach #medical #rectum #gallbladder #cecum #rhodinol #esophagus #citronellol #geraniol #healthyfood #food #ileum #jejunum #anatomia #mbbs #m #understand #pharmedical #humanbody #medicalmarijuana #atypicalmycobactetiuminfection #smallbowel #duodenumrelation #duodenumanatomy Telegram :- https://t.me/EduLesson WhatsApp :- https://bit.ly/39oLtaF Instagram:-   / edulesson   ****************************************************** All MBBS Books with Buy Link From Amazon for India - https://bit.ly/2P1pjSe MBBS First Year Textbook sets (14 books sets) With Free Dissection Kit Unknown Binding - https://amzn.to/2P259aL Best MBBS Books For You :- B.
