Digestive system

Which constituent of bile is known to have a significant digestive function

Bile salts

Salivary amylase digests

Carbohydrates

Triglycerides are digested to release fatty acids and monoglycerides. These two components are absorbed through the intestinal mucosa and enzymatically reunited again as triglycerides. What is the name of the structures that are absorbed into the lacteals

Chylomicrons

The final product of the upper digestive system that empties from the stomach into the small intestine is properly called

Chyme

Which of the following is a function of the liver

Detoxification of harmful substances

Which of the following are the three layers of the tooth

Enamel, dentin, pulp

Which of the following are alimentary canal organs

Esophagus, stomach, small intestine

Cholecystokinin (CCK) stimulates the release of bile from the pancreas

False

Fat soluble vitamins: Vitamin A, Vitamin D, Vitamin E, Vitamin K. Water soluble vitamins: Thiamine, Riboflavin, Niacin, Pantothenic acid, B6, B12, Folic acid, Biotin, Vitamin C.

To perform their filtering role, and push blood through and support liver cells, sinusoids must receive blood directly from branches of the

Hepatic artery and the hepatic portal vein

Stomach cells secrete a hormone called gastrin, which

Increases secretion by gastric glands

Which of the following is needed to digest lipids

Lipase

The digestive system

Mechanically and chemically breaks down food for nutrient absorption

Involuntary muscle contractions which move a bolus through the alimentary canal are called

Peristalsis

One of the major functions of the large intestine is to

Reabsorb water from chyme

The function of digestive enzymes is to

Speed up chemical digestion

Hydrochloric acid is secreted in the

Stomach

The digestive process includes CHEMICAL DIGESTION, which breaks the chemical bonds of complex, NON ABSORBABLE food molecules into smaller, ABSORBABLE molecules. Chemical digestion involves the addition of WATER in a process known as hydrolysis. DIGESTIVE ENZYMES are proteins that act to speed up hydrolysis reactions. For example, food encounters the following enzymes as it passes down the alimentary canal: In the oral cavity, SALIVARY AMYLASE speeds up the hydrolysis of STARCH and glycogen. Chief cells in the stomach secrete, PEPSIN, which speeds up the hydrolysis of PROTEINS. In the small intestine, TRYPSIN from pancreatic secretions speeds up the hydrolysis of PROTEINS.

Which of the following is a vitamin produced by bacteria in the colon

Vitamin K

When the swallowing reflex is activated, the SOFT PALATE contracts upward, which prevents food from entering NASAL CAVITY. At the same time, muscle contractions raise the LARYNX, which causes the EPIGLOTTIS to cover the opening into the AIRWAYS, preventing food from entering the TRACHEA and directing it to the ESOPHAGUS. When the food enters the esophagus, PERISTALSIS in the smooth muscle walls of the esophagus moves the food toward the STOMACH. At the junction of the esophagus and stomach, the CARDIAC SPHINCTER prevents regurgitation of food back into the esophagus.

Most nutrient absorption occurs in the

small intestine

Protein digestion begins in the

stomach
