Chief cells in the stomach wall secrete:
A glycoprotein required for the absorption of Vitamin B12 in the small intestine is called:
Denatures proteins, inactivates enzymes, breaks down plant cell walls and connective tissues in meat, kills microorganisms, is essential for the activation and function of pepsin.
pH of the stomach
The head of the pancreas fits into the:

Condition in which the lingual frenulum is too restrictive and the patient cannot eat or speak normally:
Urine leaving the kidney travels along the following sequential pathway to the exterior:
Ureters, Urinary Bladder, Urethra
Hormones secreted by this structure play a major role in the control of secretions of many organs involved in digestion:
This structure regulates the flow of chyme into the small intestine from the stomach:
Storage of fecal material prior to defecation, absorption of vitamins liberated by bacterial action, reabsorption of water and compaction of feces.
Major functions of the large intestine
The __________ separates the small intestine from the large intestine from backing into the small intestine.
Gallbladder is the organ that stores bile and without that extra bile storage space you may have problems with the effectiveness of _______________ when you eat.
Fat digestion and absorption
The part of the colon that empties into the rectum is the:
The Ligamentum teres, or round ligament, contains the remnant of the umbilical fetal vein. This structure can be found in the falciform ligament of the:
Retroperitoneal, surrounded by fat, move down about 1" during respiration, found between T12-L3.
The enzyme(s) that begin the process of starch digestion in the mouth:
The muscular wall of the urinary bladder consists of three layers of smooth muscle which contracts to expel urine into the urethra. It is known as the _________ muscle.
Chemical digestion of protein first begins in the:
This organ secretes a solution that helps to buffer the acids arriving in chyme to the duodenum.
Pepsinogen is a proenzyme (zymogen) that breaks down proteins once converted to pepsin. It is secreted by the:
Amylase is an enzyme that breaks down carbohydrates. It is secreted by the:
Bile is an emulsifying fluid that breaks down lipids. It is secreted by the:
Which is secreted by the small intestine?
Secretin, CCK, GIP
The three phases of deglutition are:
Buccal, pharyngeal, esophageal
The contractions of the stomach are inhibited by:
Responsible for muscular propulsion of materials into the esophagus:
This structure is responsible for the chemical breakdown of materials via acid and enzymes; mechanical processing through muscular contractions:
The maxilla and palatine bones form the:
This is the minimal resting energy expenditures of an awake, alert person. It estimates the rate of energy use by the body:
Basal Metabolic Rate
Fish is a good source of:
Iodine deficiency can result in:
Lies in the lower part of the peritoneal cavity and pelvis, plicae circulares, smaller in upper part, absent in lower part/ aggregations of lymphoid tissue (Peyer's patches) (20-30) present in mucous membrane of lower portion.
A cholecystectomy would result in a _________ ability to digest fats.
People learn about 20% of what they _____.
People learn abut 70% of what they ______.

Severe constipation can be life threatening and death often occurs in a matter of days.
The defecation reflex involves two negative feedback reflexes.
Dieting may be a major cause of obesity.
Antibiotics can interfere with birth control pills by reducing the bacterial population in the small intestine.
Secretin functions to inhibit parietal and chief cell activity.
A drop below pH 4.5 in the duodenum stimulates the secretion of secretin.
A high fat meal will lower the level of cholecystokinin in the blood.
Parietal cells produce a substance that binds to B12 which is called:
G cells in the pyloric region of the stomach secrete the hormone _________ that stimulates parietal cells to secrete HCl and chief cells to secrete pepsinogen. This hormone also stimulates contractions of the stomach wall and relaxes the pyloric sphincter.
Cells called "D" cells in the pyloric region of the stomach secrete the hormone ____________ that inhibits the release of gastrin.
The presence of chyme (lipids and carbohydrates) in the duodenum stimulates the production of _________, which inhibits gastric secretion of acids and enzymes, and ___________ which inhibits gastric secretion and reduces the rate and force of gastric contractions. As a result, the fatty meal stays in the stomach longer and enters the duodenum slower than a low-fat meal.
Cholecystokinin (CCK) / Gastric Inhibitory Peptide (GIP)
A drop in pH below 4.5 stimulates enteroendocrine cells in the duodenum to secrete the hormone ________, which inhibits parietal and chief cell activity, stimulates production of buffers, neutralizes acid in chyme and stimulates the secretion of bile.
