Question 1
Which of the following structures is primarily responsible for
filtering blood in the kidney?
A) Ureter
B) Glomerulus
C) Loop of Henle
D) Collecting duct
Answer: B) Glomerulus
Rationale: The glomerulus is the capillary network within the
nephron that filters blood to form the initial urine filtrate. While
,Page 2 of 161
other parts of the nephron modify the filtrate, filtration itself
occurs at the glomerulus. The ureter transports urine, the loop of
Henle concentrates urine, and the collecting duct carries urine to
the renal pelvis .
Question 2
The organelle responsible for ATP production in eukaryotic cells
is the:
A) Nucleus
B) Mitochondria
C) Endoplasmic reticulum
D) Golgi apparatus
Answer: B) Mitochondria
Rationale: Mitochondria generate ATP through oxidative
phosphorylation, providing energy for cellular processes. The
nucleus contains genetic material, the ER synthesizes proteins and
,Page 3 of 161
lipids, and the Golgi apparatus modifies and packages
proteins .
Question 3
Which of the following is the functional unit of the nervous
system?
A) Axon
B) Neuron
C) Dendrite
D) Myelin sheath
Answer: B) Neuron
Rationale: The neuron is the fundamental functional unit of the
nervous system, responsible for receiving, processing, and
transmitting electrochemical signals. Axons and dendrites are
parts of neurons, and myelin sheaths insulate axons .

Question 4
The mitral valve separates which two chambers of the heart?
A) Right atrium and right ventricle
B) Left atrium and left ventricle
C) Right ventricle and pulmonary trunk
D) Left ventricle and aorta
Answer: B) Left atrium and left ventricle
Rationale: The mitral valve (bicuspid valve) separates the left
atrium from the left ventricle. It prevents backflow from the left
ventricle into the left atrium during systole .
Question 5
Which hormone is primarily responsible for lactation (milk
production) in mammals?
A) Estrogen
B) Progesterone
