1. What is the role of pepsin? Why is it secreted in an inactive form?
Ans: pg. 902, 904 – a) break peptide bonds between amino acids; b) in the inactive form pepsinogen, it cannot digest the proteins in the chief cells that produce it
23. What are the functions of gastric lipase and lingual lipase in the stomach?
Lingual lipase aids in hydrolyzing (breakdown) triglycerides into fatty acids and diglycerides while Gastric Lipase hydrolyzes (breakdown) triglycerides into fatty acids and monoglycerides.
24. Describe the duct system connecting the pancreas to the duodenum.
The common bile duct (which carries bile from the liver and gallbladder) and the main pancreatic duct (which carries pancreatic juice from the pancreas) joined together to form the hepatopancreatic ampulla, which opens into the duodenum to assist in digestion. The flow of bile and pancreatic juice into the duodenum is controlled by the sphincter of Oddi (muscular valve).
25. What are pancreatic acini? How do their functions differ from those of the pancreatic islets (islets of Langerhans)?
The pancreatic acini are the functional part of the exocrine pancreas. It manufactures and produce digestive enzymes.
The functional difference between the pancreatic acini and pancreatic islets is that
pancreatic acini secrete digestive juices while pancreatic islets secrete digestive hormones
26. What are the digestive functions of the components of pancreatic juice?
Gallstones are not that unordinary. They happen to numerous individuals around the globe. Be that as it may, don't give up, there is something the Chinese thought about and now they have imparted to the world.
Our gallbladder is a 4 inches organ with the type of pear. It is set under the liver.
The gallbladder stores the bile, a blend of fluids, fat and cholesterol. The bile deteriorates the fats of the sustenance in the digestion systems. The gallbladder conveys the bile in the small…

Fresh dandelion greens can be cooked and eaten as a potherb, added to soups and salads, or used in recipes in the same way as other leafy greens. Dandelion greens contain a large number of nutrients, including vitamins A, C, E, several of the B vitamins, zinc, lecithin, magnesium and iron. They also contain especially high amounts of potassium. The calcium, silicon and boron found in dandelion greens help to protect against osteoporosis. Dandelion greens are slightly bitter, and stimulate bile…
gastric mucosa and is physically turned into chyme. Peristalis starts near the gastroesophageal sphincter causing the stomach wall to ripple. Small amounts of chyme filter through the pyloric valve via a back and forth pumping action. Depending on the size and contents of the meal the stomach empties chyme into the duodenum within four to six hours. As chyme enters the duodenum, receptors in the wall signal an inhibiting mechanism for acid and pepsin secretion. When fatty chyme enters the…
Gallstones are formed when a chemical imbalance in the bile chemical makeup occurs and roughly effects about 10-15% of all Western adults.4 In the human body, the gallbladder produces bile which is made up of components of not only bile salts and phospholipids but also cholesterol. When the liver secretes an excessive amount of cholesterol or an increase consumption of salt and water, build up of cholesterol occurs in the gallbladder forming a gallstone. Often, gallstones are small enough to…
Dear Sir or Madam,
Situated in the abdomen of vertebrates, and involved in many metabolic processes, I for one Liver, remain the second-largest organ. I perform numerous processes assisting with digestion, metabolism, immunity, including the storage of nutrients. I’m a glandular organ divided by openings. I operate in the emission of bile (Greenish liquid that responsible for chemical digestion of fats if your unaware) along with numerous metabolic processes. These processes are essential for…
The primary biliary cirrhosis (PBC) is a condition that affects the liver and destroys the bile duct in the liver. Bile is a fluid that plays an important role of digesting foods and help to get rid of the toxins in the body (MayoClinic, 2014). Sodium concentration requires to be tested in order to identify any abnormal concentration of sodium. In the case study, the patient’s sodium level was 121 mmol/L but her TC value was 322 milligrams per deciliter (Farooqi & Hashim. 2015). The normal range…
It usually affects the 3rd and/or 4th parts of the duodenum.
Presents with vomiting of the gastric contents (usually contain bile).
It is complete occlusion of the duodenal lumen as a result of failed recanalization.
It usually affects duodenum just distal to the bile duct opening, and associates with polyhydramnios (excess of amniotic fluid).
Presents after few hours of birth by bile stained vomiting.
The diagnosis is usually predicted by seeing a ‘double-bubble sign’ on…
