Question 1: Which of the following structures is responsible for filtering the blood
in the human body?
• A) Heart
• B) Liver
• C) Kidneys
• D) Lungs
CORRECT ANSWER: C) Kidneys
Rationale: The kidneys filter waste products from the blood and regulate fluid balance
and electrolyte levels in the body.
Question 2: What is the pH level of pure water at 25°C?
• A) 0
• B) 3
• C) 7
• D) 14
CORRECT ANSWER: C) 7
Rationale: Pure water has a neutral pH of 7 at 25°C, indicating a balance between
hydrogen ions (H⁺) and hydroxide ions (OH⁻).
Question 3: In which part of the cell does cellular respiration primarily occur?
• A) Nucleus
• B) Cytoplasm
• C) Mitochondria
• D) Endoplasmic Reticulum
,CORRECT ANSWER: C) Mitochondria
Rationale: Cellular respiration takes place mainly in the mitochondria, where glucose
and oxygen are converted into energy, carbon dioxide, and water.
Question 4: Which of the following best describes the function of hemoglobin?
• A) Transporting nutrients
• B) Carrying oxygen
• C) Protecting against infections
• D) Clotting blood
CORRECT ANSWER: B) Carrying oxygen
Rationale: Hemoglobin is a protein in red blood cells that binds to oxygen and
transports it from the lungs to tissues throughout the body.
Question 5: What is the primary purpose of the integumentary system?
• A) Protection and regulation of body temperature
• B) Digesting food
• C) Circulating blood
• D) Producing hormones
CORRECT ANSWER: A) Protection and regulation of body temperature
Rationale: The integumentary system, which includes the skin, hair, and nails, serves
as a barrier against environmental hazards and helps regulate body temperature.
Question 6: Which blood type is known as the universal donor?
• A) A
• B) O
• C) AB
• D) B
CORRECT ANSWER: B) O
Rationale: Type O blood is considered the universal donor because it can be given to
any blood type without causing an immune response.
Question 7: What is the primary role of the large intestine in digestion?
• A) Absorption of nutrients
, • B) Absorption of water
• C) Digestion of fats
• D) Production of bile
CORRECT ANSWER: B) Absorption of water
Rationale: The large intestine absorbs water and electrolytes, as well as compacts
waste for elimination.
Question 8: Which of the following is a function of the skeletal system?
• A) Hormone production
• B) Blood flow regulation
• C) Support and movement
• D) Nutrient absorption
CORRECT ANSWER: C) Support and movement
Rationale: The skeletal system provides support, enables movement, and protects vital
organs.
Question 9: What is the process by which cells divide to create gametes?
• A) Mitosis
• B) Meiosis
• C) Binary fission
• D) Cloning
CORRECT ANSWER: B) Meiosis
Rationale: Meiosis is the specialized cell division process that produces gametes
(sperm and eggs) with half the chromosome number.
Question 10: Which organ is primarily responsible for detoxification in the human
body?
• A) Heart
• B) Liver
• C) Kidneys
• D) Pancreas
, CORRECT ANSWER: B) Liver
Rationale: The liver detoxifies chemicals and metabolizes drugs, playing a vital role in
maintaining the body's chemical balance.
Question 11: What is the main energy currency of the cell?
• A) NADH
• B) ATP
• C) FADH2
• D) GTP
CORRECT ANSWER: B) ATP
Rationale: Adenosine triphosphate (ATP) serves as the primary energy carrier in cells,
providing energy for various cellular processes.
Question 12: Which of the following structures transports air to the lungs?
• A) Alveoli
• B) Trachea
• C) Bronchial tubes
• D) Pharynx
CORRECT ANSWER: B) Trachea
Rationale: The trachea is the windpipe that connects the throat with the lungs,
facilitating air transport.
Question 13: Which vitamin is essential for blood clotting?
• A) Vitamin A
• B) Vitamin K
• C) Vitamin C
• D) Vitamin E
CORRECT ANSWER: B) Vitamin K
Rationale: Vitamin K is critical for the synthesis of proteins required for blood clotting.
Question 14: In humans, which structure is responsible for producing insulin?
• A) Liver
