Gastrointestinal, Renal, Endocrine, and Musculoskeletal Systems
SECTION 1: GASTROINTESTINAL SYSTEM - NORMAL FUNCTION
Question 1
What is the normal function of the stomach?
A) Absorption of nutrients and elimination of waste
B) Reservoir for food and fluid, breakdown and digestion of food, release of
chemical enzymes, and formation of chyme
C) Production of bile and storage of sugar
D) Regulation of fluid and electrolyte balance
Answer-: B) Reservoir for food and fluid, breakdown and digestion of food,
release of chemical enzymes, and formation of chyme
Explanation: The stomach functions as a reservoir for food and fluid, breaks down
and digests food through chemical enzymes (pepsin, acid, and gastrin), and
,converts gastric contents into chyme before releasing it into the small intestine for
further digestion and absorption.
Question 2
What chemicals are involved in gastric function?
A) Lipase, trypsin, and amylase
B) Pepsin, acid, and gastrin
C) Insulin and glucagon
D) Bile and bilirubin
Answer-: B) Pepsin, acid, and gastrin
Explanation: The stomach utilizes three primary chemicals: pepsin (an enzyme that
breaks down proteins), hydrochloric acid (creates acidic environment for
digestion), and gastrin (a hormone that stimulates gastric acid secretion).
Question 3
What is the normal function of the small intestine?
A) Storage of bile and concentration of digestive juices
B) Absorption of nutrients occurs here; contains lactase and has three parts:
duodenum, jejunum, and ileum
C) Fluid and electrolyte balance only
D) Production of digestive enzymes
Answer-: B) Absorption of nutrients occurs here; contains lactase and has three
parts: duodenum, jejunum, and ileum
Explanation: The small intestine is the primary site of nutrient absorption. Its
folded structure (like an accordion) increases surface area for absorption. It
contains lactase for milk sugar digestion and is divided into three sections:
duodenum, jejunum, and ileum.
Question 4
,What is the normal function of the large intestine (colon)?
A) Production of digestive enzymes
B) Absorption of nutrients
C) Maintaining fluid and electrolyte balance, with resistant bacteria assisting in
food breakdown, and peristalsis
D) Secretion of hydrochloric acid
Answer-: C) Maintaining fluid and electrolyte balance, with resistant bacteria
assisting in food breakdown, and peristalsis
Explanation: The large intestine (colon) maintains fluid and electrolyte balance by
absorbing water and electrolytes. Resistant bacteria assist in breaking down
remaining food particles. Peristalsis moves contents through its three parts:
ascending, transverse, and descending colon.
Question 5
What are the three parts of the large intestine?
A) Duodenum, jejunum, ileum
B) Fundus, body, pylorus
C) Ascending, transverse, descending
D) Hepatic, splenic, sigmoid
Answer-: C) Ascending, transverse, descending
Explanation: The large intestine is divided into three main sections: the ascending
colon (travels upward on the right side), the transverse colon (crosses the
abdomen), and the descending colon (travels downward on the left side).
Question 6
What is the normal function of the gallbladder?
A) Produces bile for fat digestion
B) Stores and concentrates bile to break down fat through the bile duct into the
small intestine
, C) Produces digestive enzymes
D) Regulates blood sugar
Answer-: B) Stores and concentrates bile to break down fat through the bile
duct into the small intestine
Explanation: The gallbladder stores and concentrates bile produced by the liver.
When fat enters the small intestine, the gallbladder contracts, releasing bile
through the bile duct to emulsify and break down fats for digestion and
absorption.
Question 7
What is bile made from?
A) Cholesterol
B) Fatty acids
C) Bilirubin
D) Enzymes
Answer-: C) Bilirubin
Explanation: Bile is produced by the liver from bilirubin, which is a waste product
from the breakdown of old red blood cells. Bile contains bile salts, bilirubin,
cholesterol, and other substances that aid in fat digestion.
Question 8
What is the normal function of the pancreas?
A) Stores bile and concentrates digestive juices
B) Releases the most acidic enzymes; has exocrine (posterior to stomach) and
endocrine (hormones) functions
C) Produces only insulin
D) Filters toxins from the blood
Answer-: B) Releases the most acidic enzymes; has exocrine (posterior to
stomach) and endocrine (hormones) functions
