1. What is the normal (complete) flow of blood through the heart?

• A. Right atrium → lungs → left atrium → body
• B. Left atrium → left ventricle → body → right atrium
• C. Right atrium → right ventricle → lungs → left atrium → left ventricle → aorta → body
• D. Right ventricle → left ventricle → body

Correct answer: C

Rationale: The correct flow of blood through the heart starts with the right atrium receiving deoxygenated blood from the body, followed by the right ventricle pumping blood to the lungs for oxygenation. Oxygenated blood then returns to the heart through the left atrium, then passes to the left ventricle which pumps it out to the body through the aorta. This flow ensures that blood is properly oxygenated before circulating through the body. Choice A is incorrect as the blood does not go directly from the left atrium to the body, skipping the left ventricle. Choice B is incorrect as it does not follow the correct flow sequence in the heart. Choice D is incorrect as it does not include the full pathway of blood through the heart.

2. What is the function of the adrenal glands?

• A. To regulate metabolism
• B. To produce bile
• C. To produce red blood cells
• D. To regulate blood glucose

Correct answer: D

Rationale: The correct answer is D: To regulate blood glucose. The adrenal glands play a crucial role in regulating blood glucose levels and the body's response to stress. Choice A, 'To regulate metabolism,' is incorrect as the primary role of the adrenal glands is not directly related to metabolism regulation. Choice B, 'To produce bile,' is incorrect because bile is produced by the liver, not the adrenal glands. Choice C, 'To produce red blood cells,' is also incorrect as the production of red blood cells primarily occurs in the bone marrow, not the adrenal glands.

3. Which of the following anatomical terms is not part of the knee?

• A. Medial collateral ligament
• B. Patella
• C. Lateral malleolus
• D. Lateral meniscus

Correct answer: C

Rationale: The lateral malleolus is a bony prominence on the lateral side of the ankle and is not part of the knee anatomy. The other options - medial collateral ligament, patella, and lateral meniscus - are all structures within the knee joint. The medial collateral ligament is located on the inner side of the knee, the patella is the kneecap, and the lateral meniscus is a cartilage structure within the knee joint. Therefore, the correct answer is C, lateral malleolus.

4. Which part of the brain is responsible for voluntary muscle movements?

• A. Medulla oblongata
• B. Cerebrum
• C. Hypothalamus
• D. Thalamus

Correct answer: B

Rationale: The question inquires about the brain region responsible for voluntary muscle movements. The correct answer is the Cerebrum. The cerebrum is the main part of the brain involved in voluntary muscle control and motor coordination. The Medulla oblongata is primarily responsible for regulating vital functions like breathing and heart rate, not voluntary muscle movements. The Hypothalamus plays a role in regulating body temperature, thirst, hunger, and other homeostatic processes. The Thalamus serves as a relay station for sensory information but is not directly responsible for voluntary muscle movements.

5. Following the scientific method, which steps would be done before gathering qualitative data?

• A. Communicate with a scientific journal
• B. Define the problem
• C. Develop a hypothesis
• D. Categorize data for statistical analysis

Correct answer: B

Rationale: In the scientific method, defining the problem is typically the initial step. Before gathering qualitative data, it is essential to clearly outline and understand the issue or question being addressed. This step helps in guiding the research process and ensures that the data collected are relevant to the problem at hand. Communicating with a scientific journal (Choice A) is not a standard step in the scientific method; it comes after the research is conducted. Developing a hypothesis (Choice C) usually follows defining the problem and precedes data collection. Categorizing data for statistical analysis (Choice D) occurs after data collection, not before gathering qualitative data.
