Question 1
Which of the following is the primary function of the respiratory
system?
A) Transport of nutrients to cells
B) Removal of metabolic waste products from the blood
C) Exchange of gases between the body and the external environment
D) Regulation of body temperature
Answer: C) Exchange of gases between the body and the external
environment
Explanation: The primary function of the respiratory system is to
facilitate gas exchange, specifically the intake of oxygen and the
expulsion of carbon dioxide. While the circulatory system transports
nutrients and waste, and the integumentary system assists with
temperature regulation, the respiratory system's core role is gas
exchange.

Question 2
A patient's lab results show a white blood cell count of 15,000 cells per
microliter. The normal range is 4,500 to 11,000 cells per microliter. This
condition is most likely indicative of which of the following?
A) Anemia
B) Leukopenia
C) Leukocytosis
D) Thrombocytopenia
Answer: C) Leukocytosis
Explanation: An elevated white blood cell count above the normal range
is termed leukocytosis. This is frequently a physiological response to
infection, inflammation, or stress. Anemia is a low red blood cell count
or hemoglobin, leukopenia is a low white blood cell count, and
thrombocytopenia is a low platelet count.
Question 3
In the process of cellular respiration, which molecule is the final
electron acceptor in the electron transport chain?
A) NADH
B) FADH2
C) Oxygen
D) Glucose
,3|Page
Answer: C) Oxygen
Explanation: Oxygen serves as the final electron acceptor at the end of
the electron transport chain. It combines with electrons and hydrogen
ions to form water. This step is crucial because it allows the chain to
continue functioning, generating ATP.
Question 4
Which of the following is a function of the Golgi apparatus?
A) Synthesis of proteins
B) Intracellular digestion of macromolecules
C) Modification, sorting, and packaging of proteins and lipids
D) Production of ribosomal RNA
Answer: C) Modification, sorting, and packaging of proteins and lipids
Explanation: The Golgi apparatus acts as the cell's post office. It receives
proteins and lipids from the endoplasmic reticulum, modifies them
chemically (e.g., adding sugars), and then sorts and packages them into
vesicles for transport to their final destinations inside or outside the cell.
Question 5
Which of the following prefixes means "above" or "upon"?
A) Hypo-
B) Hyper-
C) Epi-
, 4|Page
D) Endo-
Answer: C) Epi-
Explanation: In medical terminology, the prefix "epi-" means "above,"
"upon," or "over." For example, the epidermis is the outer layer of skin.
"Hypo-" means "below" or "under," "Hyper-" means "excessive" or
"above normal," and "Endo-" means "within" or "inner."
Question 6
Which of the following correctly lists the levels of organization in the
human body from simplest to most complex?
A) Tissue, Cell, Organ, Organ System, Organism
B) Cell, Organ, Tissue, Organ System, Organism
C) Cell, Tissue, Organ, Organ System, Organism
D) Organelle, Cell, Organ, Tissue, Organ System
Answer: C) Cell, Tissue, Organ, Organ System, Organism
Explanation: The human body is organized hierarchically. The cell is the
basic unit of life. Similar cells form tissues, different tissues combine to
form organs, organs work together in organ systems, and all systems
cooperate to form a complete organism.
