Question

Draw a neat labeled diagram of the pancreas with their associated structure.

Answer 1

Hint: Pancreas is an abdominal organ that is located behind the stomach and is surrounded by other organs like the liver, intestine, gallbladder, etc. These organs are part of the digestive system.

Complete answer:
The digestive system helps in the digestion of food along with its excretion and absorption of nutrients.
The pancreas is the compound gland (both exocrine and endocrine). It is an elongated organ situated in the limbs of ‘U’ shaped duodenum. The parts of the pancreas are, Head, body, and tail. The head of the pancreas lies in the ‘C’ shaped curvature of the duodenum. The body is the largest part of the pancreas that lies behind the stomach and is tapering in shape. The tail sits near the spleen. The exocrine part of the pancreas secretes an alkaline pancreatic juice containing digestive enzymes, whereas the endocrine part of the pancreas secretes insulin and glucagon hormones.
The stomach lies above the pancreas. It is a J-shaped muscular cavity. It has three major parts-a cardiac portion into which the esophagus opens, the fundus region, and the pyloric portion which opens in the first part of the small intestine.
The spleen is an organ that acts as a blood filter. The spleen is underneath the left part of the diaphragm and is in contact with the stomach. The tail of the pancreas is in contact with the concave part of the spleen.
The small intestine is distinguished into 3 regions, Duodenum, Jejunum, and ileum. It is an organ where the majority of digestion, absorption of the nutrients take place. The small intestine is the largest organ that is coiled and lies between the stomach and large intestine.
The large intestine consists of Caecum, Colon, and Rectum. The caecum is a small blind sac that hosts some symbiotic microorganisms. Vermiform appendix arises from caecum is vestigial in human beings. An ascending, a transverse, and a descending colon are the three parts of colon. The descending part opens into the rectum. Ascending colon is the smallest part.

Note: The bile is stored and concentrated in the gallbladder. The ducts of gallbladder along with hepatic duct from the liver form the common bile duct. This bile duct and pancreatic duct open together into the duodenum as the common hepatopancreatic duct.
