1. Specialized cell types organized in a way that provides a specific function form

• A. tissues, which build organs.
• B. organs, which build tissues.
• C. organ systems, which build tissues.
• D. atoms, which comprise tissues.

Correct answer: A

Rationale: The correct answer is 'tissues, which build organs.' Specialized cell types organize to form tissues, which in turn build organs. Tissues are groups of cells that work together to perform a specific function. Option B is incorrect because organs are composed of tissues, not the other way around. Option C is incorrect as organ systems consist of multiple organs working together, not building tissues. Option D is incorrect as atoms are the basic building blocks of matter and are not directly involved in forming tissues.

2. What is the maximum capacity of a normal adult bladder before involuntary micturition is likely to occur?

• A. 800-900ml
• B. 300-600ml
• C. 1000-2000ml
• D. 400-700ml

Correct answer: B

Rationale: The correct answer is B: 300-600ml. A normal adult bladder can hold approximately 300-600ml of urine before the urge to urinate becomes strong and involuntary micturition is likely to occur. Choice A (800-900ml), Choice C (1000-2000ml), and Choice D (400-700ml) all exceed the typical capacity of a normal adult bladder and would generally not be accurate in the context of involuntary micturition.

3. What is the main function of the digestive system?

• A. Formation of cells
• B. Movement of body parts
• C. Absorption of nutrients
• D. Providing oxygen for the extraction of energy from nutrients

Correct answer: C

Rationale: The correct answer is C: Absorption of nutrients. The main function of the digestive system is to break down food into nutrients that can be absorbed by the body to provide energy and support bodily functions. Choice A, 'Formation of cells,' is incorrect as cell formation is not the primary function of the digestive system; it is more related to processes like cell division and growth. Choice B, 'Movement of body parts,' is incorrect as this is more related to the muscular system, which controls body movements. Choice D, 'Providing oxygen for the extraction of energy from nutrients,' is incorrect because providing oxygen is primarily the function of the respiratory system, which is responsible for breathing and oxygen exchange in the body, not the digestive system.

4. Homeostasis is the body's maintenance of a stable internal environment.

• A. TRUE
• B. FALSE
• C. Not Sure
• D. None of the above

Correct answer: A

Rationale: Homeostasis refers to the body's ability to maintain a stable internal environment despite external changes. It involves processes that regulate various physiological factors such as temperature, pH, and blood sugar levels within a narrow range. This ensures that the body's cells can function optimally. Therefore, the correct answer is True. Choices B, C, and D are incorrect because homeostasis aims to maintain stability, not instability, in the internal environment.

5. Are the ears lateral to the eyes?

• A. True
• B. False
• C. Not Sure
• D. None of the above

Correct answer: A

Rationale: The correct answer is A: True. Lateral means towards the side or away from the midline. In human anatomy, the ears are located on the sides of the head, which is indeed lateral to the eyes that are positioned more towards the front of the face. Therefore, the statement that the ears are lateral to the eyes is true. Choice B is incorrect because the ears are not positioned closer to the midline than the eyes. Choice C is incorrect as the relationship between the ears and eyes in terms of lateral positioning can be determined anatomically. Choice D is incorrect as there is a clear anatomical relationship between the ears and eyes.
