Finals Exam (Qns & Ans)
2025
General Instructions
1. Read All Questions Carefully: Make sure you understand each question.
2. Time Management: You have a specific amount of time to complete the exam.
Keep an eye on the clock and pace yourself.
3. Allowed Materials: Only use materials that are explicitly allowed. Unauthorized
materials can lead to disqualification.
4. ANS Format: Follow the required format for your ANS. For example, multiple-
choice questions might need you to select the best ANS, while essay questions
require detailed responses.
5. Academic Integrity: Adhere to the university's honor code. Any form of cheating or
plagiarism is strictly prohibited.
6. Technical Requirements: Ensure your computer and internet connection are
stable. For online exams, you might need a webcam and microphone for proctoring
purposes.
7. Submission: Submit your ANS before the time expires. Late submissions might
not be accepted.

,1. Which of the following hormones primarily regulates blood
glucose levels?
a) Cortisol
b) Insulin
c) Glucagon
d) Adrenaline
Correct ANS: b) Insulin
Rationale: Insulin is produced by the pancreas and is crucial
for lowering blood glucose levels by facilitating cellular uptake.
2. What part of the nephron is primarily responsible for
filtration?
a) Loop of Henle
b) Collecting duct
c) Glomerulus
d) Proximal convoluted tubule
Correct ANS: c) Glomerulus
Rationale: The glomerulus is a network of capillaries
responsible for filtering blood to form urine.

,3. During which phase of the cardiac cycle does ventricular
filling occur?
a) Isovolumetric contraction
b) Ventricular systole
c) Atrial systole
d) Diastole
Correct ANS: d) Diastole
Rationale: During diastole, the heart relaxes, allowing the
ventricles to fill with blood.
4. Which type of muscle is involuntary and striated?
a) Cardiac muscle
b) Skeletal muscle
c) Smooth muscle
d) None of the above
Correct ANS: a) Cardiac muscle
Rationale: Cardiac muscle is found in the heart, is
involuntary, and contains striations.
5. The conduction system of the heart is primarily initiated by
which structure?
a) Atrioventricular node

, b) Sinoatrial node
c) Bundle of His
d) Purkinje fibers
Correct ANS: b) Sinoatrial node
Rationale: The sinoatrial (SA) node is the natural pacemaker
of the heart that initiates the electrical impulses.
Fill-in-the-Blank Questions
6. The main function of the _________ is to facilitate gas
exchange in the lungs.
Correct ANS: alveoli
Rationale: Alveoli are tiny air sacs in the lungs that promote
the exchange of oxygen and carbon dioxide.
7. _________ is the process by which water and solutes are
reabsorbed in the kidneys.
Correct ANS: Reabsorption
Rationale: Reabsorption is the mechanism by which the
kidneys reclaim water and essential solutes from filtrate.
