The bile duct and pancreatic duct join to form the hepatopancreatic ampulla and empty their secretions into the duodenum through the hepatopancreatic sphincter.
True
False
Cholecystokinin is made by parietal cells of the stomach.
True
False
The major function of the large intestine is defecation.
True
False
The conversion of pepsinogen into pepsin is a necessary step in protein digestion in the stomach and cannot be done without HCl.
True
False
Renin, which is secreted by the kidneys, acts on angiotensin to form angiotensin II, which is then converted to angiotensin I by ACE. Angiotensin II then stimulates the release of aldosterone and ADH. Angiotensin II acts to stabilize blood pressure and volume.
True
False
Hyponatremia is defined as an excess of Na+ in the blood serum.
True
False
The stomach is the first site of protein digestion and hormone release.
True
False
Fat breakdown products are solubilized by bile salts.
True
False
Secretin, which is released by enteroendocrine cells of the small intestine, is released upon pancreatic juices entering the duodenum.
True
False
The kidneys reabsorb almost all of the Na+ as filtrate passes through its tubules.
True
False
Hepatocytes line the outside of the blood vessels which run from the center of a liver lobule to the portal triads.
True
False
The afferent arteriole guides blood to the glomerulus while the efferent arteriole guides blood away from it.
True
False
The proximal convoluted tubule reabsorbs water, Na+, HCO3- and glucose, among other nutrients.
True
False
K+ is the major cation of the ECF.
True
False
The Islets of Langerhans are groups of pancreatic endocrine cells that secrete insulin and pancreatic juice while acinar cells secrete glucagon.
True
False
What effect does cholecystokinin have on the gallbladder?
Causes gall bladder expansion
Causes gall bladder contraction
No effect
What is the most common cause of chronic kidney disease?
Diabetes mellitus
High blood pressure
Low blood pressure
Kidney stones
What causes the gastric phase to begin?
The stretching of stomach stretch receptors due to the entering of food.
The stretching of the stomach contracts receptors due to the entering of food.
What is the function of angiotensin II?
Inhibit aldosterone release from the adrenal gland.
Targets the adrenal cortex to secrete aldosterone; stimulates arterioles to constrict and production of ADH from the hypothalamus.

Where does the majority of the reabsorption occur in the nephron?
Distal Convoluted Tubule
Ascending Limb of Nephron Loop

The process of small molecules passing through the epithelial cells into the blood for distribution to body cells is called "Absorption"
True
False
What is the process that transports urine from the kidneys to the bladder?
Defecation
Peristalsis
Deglutition
Segmentation
How do the kidneys compensate for respiratory acidosis?
By absorbing more H+ and decreasing HCO3-
By excreting more H+ and generating more HCO3- to buffer the blood.
By absorbing more H+ and generating more HCO3- to buffer the blood.
By excreting more H+ and decreasing HCO3-
