1. An anatomical section that separates the body into right and left portions is a _______ section.

• A. frontal
• B. transverse
• C. coronal
• D. sagittal

Correct answer: D

Rationale: The correct answer is 'sagittal.' A sagittal section divides the body into right and left portions. Choice A, 'frontal,' is incorrect as it divides the body into front and back portions. Choice B, 'transverse,' divides the body into upper and lower portions. Choice C, 'coronal,' divides the body into anterior and posterior portions. Therefore, 'sagittal' is the most appropriate term for a section separating the body into right and left portions.

2. Cells do not aggregate into organelles based on similar functions.

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

Correct answer: B

Rationale: The statement is false. Cells with similar functions do not aggregate into organelles. Organelles are specialized structures within cells that perform specific functions, such as the nucleus, mitochondria, and endoplasmic reticulum. Cells themselves are the basic structural and functional units of organisms, and organelles are located within cells to carry out various tasks. Therefore, cells do not aggregate into organelles, but organelles are found within cells to support their functions. Choices A, C, and D are incorrect as cells do not form organelles by aggregating based on similar functions.

3. What is the membrane on the surface of a lung called?

• A. visceral pleura
• B. parietal pleura
• C. visceral pericardium
• D. parietal pericardium

Correct answer: A

Rationale: The correct answer is A: visceral pleura. The membrane covering the surface of the lungs is called the visceral pleura. It is a serous membrane that is in direct contact with the lung tissue. Choices B, C, and D are incorrect because the parietal pleura covers the inner surface of the chest wall and diaphragm, the visceral pericardium covers the surface of the heart, and the parietal pericardium is the outer layer of the pericardium surrounding the heart, respectively.

4. Why are anatomy and physiology difficult to separate?

• A. Physiological functions depend on anatomical structures.
• B. Physiological functions in an organism are ongoing.
• C. Body parts provide structural support.
• D. Our understanding of physiology is changing more than our understanding of anatomy.

Correct answer: A

Rationale: Anatomy and physiology are difficult to separate because physiological functions depend on anatomical structures. The correct answer highlights the interdependence between the two disciplines; physiological functions are carried out by anatomical structures. Choice B is incorrect as it only states a characteristic of physiological functions without addressing the relationship with anatomy. Choice C is incorrect as it talks about body parts providing structural support, which is not directly related to the interdependence of anatomy and physiology. Choice D is incorrect because the rate of change in understanding does not necessarily dictate the difficulty of separating the two disciplines.

5. Which of the following processes does not help maintain the life of an individual organism?

• A. Responsiveness
• B. Movement
• C. Reproduction
• D. Respiration

Correct answer: C

Rationale: Reproduction is the correct answer because it is not essential for maintaining the life of an individual organism. While reproduction is crucial for the continuation of a species, it is not directly related to the survival or maintenance of an individual organism. Responsiveness allows an organism to react to stimuli, movement helps in obtaining resources and avoiding danger, and respiration provides the necessary energy for life processes. Therefore, reproduction is the process that does not directly contribute to maintaining the life of an individual organism.
