Questions With Correct Answers
In the gastrointestinal tract, smooth muscle is the main muscle type
(True/False) - answer✔True
In our body, approx. 8 liters of intestinal juices are secreted into the GI tract daily, but only 100
ml of water is secreted into the feces.
(True/False) - answer✔True
Normal movement of blood flow in the heart is: left atrium-left ventricle- lung- right atrium-
right ventricle.
(True/False) - answer✔False.
Right atrium-right ventricle-lung-left atrium-left ventricle.
Normally, humans have 2 lobes in the right lung and 3 lobes in the left lung.
(True/False) - answer✔False.
It is the opposite.
In the lung, gas exchange occurs mostly at the alveoli.
(True/False) - answer✔True
The urinary system is normally composed of two kidneys, two ureters and two bladders.
(True/False) - answer✔False.
2 Kidneys, 2 ureters, 1 bladder.
Filtered wastes from the glomerulus will move in the following order: Bowman's capsule-
proximal tubule-distal tubule-loop of henle- collecting duct.
(True/False) - answer✔False.
Bowman's capsule- proximal tubule- loop of henle- distal tubule- collecting duct.
Specificity of hormone action in the target cells is determined by receptors.
(True/False) - 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? - answer✔Lipids (phospholipids)
Where is the concentration of [K+] greater?
Cytoplasm or extracellular fluid? - answer✔Cytoplasm
Across a cell's plasma membrane, movement of water is (passive through a channel or an active
event)? - answer✔Passive through a channel
Where is the concentration of [Na+] greater?
Cytoplasm or Extracellular fluid? - answer✔Extracellular fluid
Regarding secondary active transport of glucose, the movement of glucose is from a
compartment of high concentration to low concentration.
(True/False) - answer✔False, it moves into the cell with sodium from low to high concentration
At what point in time does the electrochemical equilibrium potential exist? - answer✔At
equilibrium
What is a major factor that regulates an electrolyte's electrochemical equilibrium potential across
a cell membrane? - answer✔Concentration (chemical) gradient
The electrochemical equlibrium potential for a single highly permeant ion species is controlled
by the concentration gradient.
(True/False) - answer✔True.
Movement of a charged electrolyte is determined by the major forces of voltage plus chemical
concentration gradients.
(True/False) - answer✔True
Which ion is primarily responsible for establishing a typical cell membrane's "resting" potential?
- answer✔K+
Excessive extracellular acid (i.e. [H+]) will raise the concentration of extracellular potassium ion
concentration.
