GMS 6440 FUNDAMENTALS FINAL ACTUAL QUESTIONS
AND CORRECT ANSWERS
T/F: Cardiac muscle contraction is False
considered to be voluntary movement. It moves involuntarily.
T/F: In the gastrointestinal tract, smooth True
muscle is the major muscle type.
T/F: In our body, approximately 8 liters of True
intestinal juices are secreted into the GI tract
daily, but only 100 ml of water is secreted
into the feces.
T/F: Normal movement of blood flow in the False
heart is: left atrium-left ventricle-lung-right Right atrium - right ventricle - lung - left atrium- left ventricle
atrium-right ventricle.
T/F: Normally, humans have 2 lobes in the False
right lung and 3 lobes in the left lung. 3 lobes in the right lung and 2 lobes in the left lung
T/F: In the lung, gas exchange occurs True
mostly at the alveoli.
T/F: The urinary system is normally False
composed of two kidneys, two ureters and Two kidneys, two ureters, and ONE bladder
two bladders.
T/F: Filtered wastes from the glomerulus will False
move in the following order: Bowman's Bowman's Capsule - proximal tubule - loop of Henle - distal
capsule-proximal tubule-distal tubule-loop tubule - collecting duct
of Henle-collecting duct.
T/F: Both endocrine and nervous systems True
play important roles in controlling the
activities of many different organ systems to
maintain homeostasis.
T/F: Specificity of hormone action in the True
target cells is determined by receptors.
T/F: The area of nerve axon not wrapped by False
myelin sheath (non-myelinated area) is Myelin sheath insulates action potential. Action potential
called nodes of Ranvier where action propagates faster by skipping myelinated axon, and jumping
potential is insulated. from nodes of Ranvier to another node.
What chemical component of the plasma Lipids (phospholipids)
membrane prevents ions from readily and
freely moving across the membrane?
Where is the concentration of [K+] greater: In the cytoplasm
- in the cytoplasm
- in the extracellular fluid
, Across a cell's plasma membrane, passive through a channel
movement of water is ________ _.
Where is the concentration of [Na+] greater: In the extracellular fluid
- in the cytoplasm
- in the extracellular fluid
For a neutrally charged molecule, "Active" from a low concentration to a high concentration
transport means that the molecules move
across a membrane:
What molecule is the source of energy for ATP
primary active transport to occur?
T/F: There is only one type of channel in cell False
membranes.
T/F: Regarding primary active transport, True
solutes move from a compartment of low
concentration to a compartment of high
concentration.
T/F: Regarding secondary active transport False
of glucose, the movement of glucose is
from a compartment of high concentration
to a compartment of low concentration.
T/F: All transport through membrane False
channels is classified as "Active" transport.
T/F: Electrolytes are pumped and leak True
across cell membranes simultaneously but
independently.
At what point in time does the at equilibrium
electrochemical equilibrium potential exist?
What is a major factor that regulates an Concentration (chemical) gradient
electrolyte's electrochemical equilibrium
potential across a cell membrane?
T/F: The electrochemical equilibrium True
potential for a single highly permeant ion
species is controlled by the concentration
gradient.
T/F: Movement of a charged electrolyte is True
determined by the major forces of voltage
plus chemical concentration gradients
