2025 Final Exam GMS 6440 Questions and Answers.
False, it moves involuntarily - correct answers ✔️✔️Cardiac muscle contraction is considered to be
voluntary movement.
True - correct answers ✔️✔️In the gastrointestinal tract, smooth muscle is enriched.
True - correct answers ✔️✔️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.
False. Right atrium-right ventricle-lung-left atrium-left ventricle - correct answers ✔️✔️Normal
movement of blood flow in the heart is: left atrium-left ventricle-lung-right atrium-right ventricle.
False. 3 lobes in the right lung and 2 lobes in the left lung. - correct answers ✔️✔️Normally, humans
have 2 lobes in the right lung and 3 lobes in the left lung.
True - correct answers ✔️✔️In the lung, gas exchange occurs mostly at the alveoli.
False. Two kidneys, two ureters and one bladder. - correct answers ✔️✔️The urinary system is normally
composed of two kidneys, two ureters and two bladders.
, False. Bowman's capsule-proximal tubule- loop of Henle-distal tubule-collecting duct. - correct answers
✔️✔️Filtered wastes from the glomerulus will move in the following order: Bowman's capsule-proximal
tubule-distal tubule-loop of Henle-collecting duct.
True - correct answers ✔️✔️Both endocrine and nervous systems play important roles in controlling the
activities of many different organ systems to maintain homeostasis.
True - correct answers ✔️✔️Specificity of hormone action in the target cells is determined by receptors.
False. Myelin sheath insulates action potential. Action potential propagates faster by skipping
myelinated axon, and jumping from nodes of Ranvier to another node. - correct answers ✔️✔T️ he area
of nerve axon not wrapped by myelin sheath (non-myelinated area) is called nodes of Ranvier where
action potential is insulated.
Lipids (phospholipids) - correct answers ✔️✔️What chemical component of the plasma membrane
prevents ions from readily and freely moving across the membrane?
Cytoplasm - correct answers ✔️✔️Where is the concentration of [K+] greater:
passive through a channel - correct answers ✔️✔️Across a cell's plasma membrane, movement of water
is _______________.
in the extracellular fluid - correct answers ✔️✔️Where is the concentration of [Na+] greater:
from low concentration to high concentration - correct answers ✔️✔F️ or a neutrally charged molecule,
"Active" transport means that the molecules move across a membrane:
ATP (adenosine triphosphate) - correct answers ✔️✔️What molecule is the source of energy for primary
active transport to occur?
False - correct answers ✔️✔️There is only one type of channel in cell membranes.
