Exam 22: Nutrition and Digestion

The stomach's gastric juice consists of ________.

What is the epiglottis?

Most humans need about ________ kcal per day.

Which of the following choices lists the organs of the human alimentary canal in the CORRECT order?

Someone with liver failure will,in particular,have problems with the digestion and absorption of ________.

Which structure stores feces until they can be eliminated?

Use the following information to answer the following questions. There are many diseases of the digestive system. Sjögren's syndrome is an autoimmune disease that destroys tear ducts and salivary glands. In megaesophagus, peristalsis fails to occur properly and the esophagus is enlarged. In achlorhydria (also called "hypochlorhydria") production of gastric acid is absent or low. When a person has diverticulitis, feces are trapped in small pouches of the large intestine, and cause infection. Infected portions of the large intestine can swell and block the large intestine. In exocrine pancreatic insufficiency, there is a progressive loss of pancreatic cells that make digestive enzymes. In gallstone cholestasis, bile cannot flow from the liver to the duodenum. -Difficulty swallowing could indicate ________.

Use the following information to answer the following questions. Several years ago, scientists discovered a mutation in zebrafish larvae that prevented the absorption of lipids from dietary fat. Larvae carrying this mutation died shortly after they hatched because all cells need fat to carry out their normal functions. More recent studies have determined that the mutation leading to this disorder occurs in a single gene on chromosome 10. When a normal gene is inserted into embryos carrying the mutation, these fish are able to process fats normally when they hatch. To discover more about the gene's function, researchers examined and compared cells from normal and mutant fish larvae under a microscope. A major difference was noticed in the intestinal cells. The Golgi apparatus in the intestinal cells of mutant larvae is much larger than those of normal larvae. As the Golgi apparatus processes fats and proteins, the lipids become trapped, resulting in the abnormally large size of the organelle. -Assuming that the digestive system of zebrafish works like that of a human,what substance do zebrafish need to make fats more easily digested by enzymes?

The figure below shows that ________.

Bile from the liver is stored in the ________ before entering the intestine.

Which of the following is the usual cause of heartburn?

What do the vitamins biotin and Vitamin K have in common?

The digestive sac of a jellyfish has ________ opening(s).

The stomach mixes food with the secretions of the stomach wall to form ________.

Examine the FDA label for the loaf of Baker Organic Bread and answer the following questions. -How many servings of bread would an average person have to eat in order to get the FDA Daily Value of the water-soluble vitamin needed for reducing the risk of birth defects?

Please refer to the following art to answer the following questions. -A person with a BMI of 27 would be described as ________.
