Explanation: The liver is the organ responsible for producing bile, which plays a crucial role in the digestion and absorption of fats.

Explanation: The small intestine is primarily responsible for the absorption of nutrients from digested food into the bloodstream.

Explanation: Heartburn is a common symptom of GERD, which is caused by the backward flow of stomach acid into the esophagus.

Explanation: Amylase is an enzyme that breaks down complex carbohydrates into smaller sugar molecules, facilitating their digestion.

Explanation: The main function of the large intestine is to absorb water and electrolytes from undigested food, leaving behind solid waste material.

Explanation: The stomach acts as a storage organ for food and performs mechanical digestion by churning and mixing the food with gastric juices.

Explanation: The correct pathway of food through the digestive system is from the esophagus to the stomach, then to the small intestine, and finally to the large intestine.

Explanation: The pancreas is responsible for producing and secreting insulin, a hormone that helps regulate blood sugar levels. Insulin is produced by Beta cell in the islet of Langerhans.

Explanation: The gallbladder stores and concentrates bile produced by the liver. Bile is released into the small intestine to aid in the digestion and absorption of fats.

Explanation: Peristalsis is the coordinated contraction and relaxation of muscles in the digestive tract that helps propel food along its pathway through the system.

Explanation: Gastroesophageal reflux refers to the backward flow of stomach acid into the esophagus, often causing symptoms such as heartburn and regurgitation.

Explanation: The salivary glands produce saliva, which contains enzymes that initiate the digestion of carbohydrates and lubricates food for swallowing.

Explanation: Lipase is an enzyme produced by the pancreas that breaks down fats into fatty acids and glycerol, facilitating their digestion and absorption.

Explanation: The epiglottis is a flap of tissue located at the base of the tongue that closes the opening to the trachea during swallowing, preventing food and liquids from entering the airway.

Explanation: Lactose intolerance is the inability to digest lactose, a sugar found in milk and dairy products. One of the common symptoms is diarrhea, which occurs due to the undigested lactose drawing excess water into the colon

Explanation: Nausea refers to the uncomfortable feeling of the urge to vomit, often accompanied by a sensation of queasiness or stomach discomfort.

Explanation: Vomiting is the forceful expulsion of stomach contents through the mouth, typically due to the contraction of the stomach muscles and the relaxation of the esophageal sphincter.

Explanation: Hematochezia refers to the presence of bright red blood in the stool, indicating bleeding in the lower digestive tract, such as the rectum or colon.

Explanation: Jaundice is the term used to describe the yellowing of the skin and eyes, resulting from an accumulation of bilirubin, a yellow pigment formed during the breakdown of red blood cells.

Explanation: Anorexia refers to the loss of appetite and aversion to food. It can be caused by various factors, including medical conditions, psychological factors, or side effects of medication.

Explanation: Constipation refers to difficulty passing stools or infrequent bowel movements. It can be caused by factors such as inadequate fiber intake, dehydration, lack of physical activity, or certain medications.

Explanation: Melena refers to the passage of black, tarry stools that contain digested blood. It is often a sign of bleeding in the upper digestive tract, such as the stomach or upper small intestine.

Explanation: An orthodontist is a dental specialist who focuses on the diagnosis, prevention, and treatment of dental and facial irregularities, particularly those related to teeth and jaw alignment.

Explanation: "Idiopathic" refers to a condition or disease that has an unknown cause. It means that the underlying reason for the condition is not yet understood or identifiable.

Explanation: Irritable bowel syndrome (IBS) is a common chronic gastrointestinal disorder that affects the large intestine. It is characterized by symptoms such as abdominal pain, bloating, and changes in bowel habits, including diarrhea and constipation.

Explanation: Coeliac disease is an autoimmune disorder in which the body's immune system reacts to gluten, a protein found in wheat, barley, and rye. This reaction causes damage to the lining of the small intestine, leading to various digestive symptoms and malabsorption of nutrients.

Explanation: Flatus refers to the release of gas from the digestive system through the rectum. It is a normal bodily function, and the average person passes gas multiple times a day.

Explanation: Volvulus is a condition characterized by the abnormal twisting or rotation of a portion of the intestine, leading to a blockage or obstruction. It can cause severe abdominal pain, nausea, and vomiting and requires immediate medical attention.

Explanation: Ulcerative colitis is a chronic inflammatory bowel disease that primarily affects the colon and rectum. It causes inflammation and ulcers in the lining of the large intestine, leading to symptoms such as abdominal pain, diarrhea, rectal bleeding, and weight loss.

Sial-: saliva

-lith: stones

A sialolith is a stone or calcification that forms within a salivary gland or its duct. It can block the flow of saliva and cause pain, swelling, and infection in the affected gland.

Explanation: Ileus refers to a condition in which there is an obstruction of the intestines, leading to a disruption of normal bowel movements. It can cause symptoms such as abdominal pain, bloating, constipation, and absence of bowel sounds.

Explanation: Laparoscopic cholecystectomy is a surgical procedure in which the gallbladder is removed using minimally invasive techniques. It involves making small incisions in the abdomen and using a laparoscope to visualize and remove the gallbladder.

Explanation: Minimally invasive surgery refers to surgical techniques that use smaller incisions and specialized instruments to perform procedures with less tissue damage and faster recovery compared to traditional open surgery.

Explanation: Pancreatoduodenectomy, also known as Whipple procedure, is a surgical procedure that involves the removal of the head of the pancreas, the duodenum, a portion of the bile duct, and sometimes a portion of the stomach and lymph nodes. It is typically performed to treat certain pancreatic and periampullary tumors.

Explanation: Pancreatojejunostomy is a surgical procedure that involves creating a connection between the pancreas and the jejunum (part of the small intestine).

Explanation: Hepaticojejunostomy is a surgical procedure that involves creating a connection between the bile ducts of the liver and the jejunum (part of the small intestine). It is performed to restore bile flow in cases where there is a blockage or injury in the bile ducts.

Explanation: Gastrojejunostomy is a surgical procedure that involves creating a connection between the stomach and the jejunum (part of the small intestine).

Explanation: Calculi, also known as stones, are hardened deposits that can form in various parts of the body, such as the gallbladder, kidneys, or urinary tract. In the context of the digestive system, gallstones are common calculi that form in the gallbladder.

Explanation: Colorectal cancer refers to cancer that originates in the colon or rectum. It is one of the most common types of cancer and can cause symptoms such as changes in bowel habits, rectal bleeding, abdominal pain, and unintended weight loss.

Explanation: Cheil- is a root word which means the tongue, and -itis is a suffix which refers to the inflammation. Therefore, Cheilitis is a medical term that specifically refers to inflammation of the lips.
