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