GMS 6440 Quiz Prep 2026 – Comprehensive
Review with Practice Questions & Solutions
Cardiac muscle contraction is considered to be voluntary movement. - correct answers -False; it moves
involuntarily
In the gastrointestinal tract, smooth muscle is enriched. - correct answers -True
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 answers -True
Normal movement of blood flow in the heart is: left atrium-left ventricle-lung-right atrium-right
ventricle. - correct answers -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. - correct answers -False; 3
lobes in the right lung and 2 lobes in the left lung.
In the lung, gas exchange occurs mostly at the alveoli. - correct answers -True
The urinary system is normally composed of two kidneys, two ureters and two bladders. - correct
answers -False; Two kidneys, two ureters and one bladder.
Filtered wastes from the glomerulus will move in the following order: Bowman's capsule-proximal
tubule-distal tubule-loop of Henle-collecting duct. - correct answers -False; Bowman's capsule-
proximal tubule- loop of Henle-distal tubule-collecting duct.
Both endocrine and nervous systems play important roles in controlling the activities of many different
organ systems to maintain homeostasis. - correct answers -True
Specificity of hormone action in the target cells is determined by receptors. - correct answers -True
1
, The area of nerve axon not wrapped by myelin sheath (non-myelinated area) is called nodes of Ranvier
where action potential is insulated. - correct answers -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 answers -Lipids (phospholipids)
Where is the concentration of [K+] greater: - correct answers -Cytoplasm
Across a cell's plasma membrane, movement of water is _______________. - correct answers -passive
through a channel
Where is the concentration of [Na+] greater: - correct answers -in the extracellular fluid
For a neutrally charged molecule, "Active" transport means that the molecules move across a
membrane: - correct answers -from low concentration to high concentration
What molecule is the source of energy for primary active transport to occur? - correct answers -ATP
(adenosine triphosphate)
There is only one type of channel in cell membranes. - correct answers -False; Ligand-gated, Voltage-
gated, Leak, Stretch-activated
Regarding primary active transport, solutes move from a compartment of low concentration to a
compartment of high concentration. - correct answers -True
Regarding secondary active transport of glucose, the movement of glucose is from a compartment of
high concentration to a compartment of low concentration. - correct answers -False; Low to High
