1. Which of the following statements is true concerning the female reproductive system?

• A. It produces female sex cells.
• B. It transports the female sex cells.
• C. It can support the development of an embryo.
• D. All of the above

Correct answer: D

Rationale: The correct answer is 'All of the above.' The female reproductive system produces female sex cells (eggs), transports them through the fallopian tubes, and can support the development of an embryo through the uterus. Choice A is correct because the ovaries produce eggs, choice B is correct as the fallopian tubes transport the eggs, and choice C is correct as the uterus provides the environment for the embryo to develop. Therefore, all of these statements are true regarding the female reproductive system.

2. 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.

3. Which of the following ions is most abundant in extracellular fluid?

• A. Calcium
• B. Chloride
• C. Sodium
• D. Potassium

Correct answer: C

Rationale: Sodium is the most abundant ion in extracellular fluid. It plays a crucial role in maintaining fluid balance, nerve function, and muscle contraction. Calcium (Choice A) is mainly found in bones and teeth, Chloride (Choice B) is the major anion in extracellular fluid but not the most abundant ion, and Potassium (Choice D) is found predominantly inside cells.

4. Which of the following cardiac valves prevents blood from returning to the left ventricle of the heart?

• A. pulmonic
• B. mitral
• C. tricuspid
• D. aortic

Correct answer: D

Rationale: The correct answer is the aortic valve. The aortic valve is located between the left ventricle and the aorta, preventing the backflow of blood into the left ventricle once it has been pumped out during systole. Choice A, pulmonic, is incorrect as it is associated with the right side of the heart. Choice B, mitral, is incorrect as it is the valve between the left atrium and ventricle. Choice C, tricuspid, is incorrect as it is located between the right atrium and ventricle.

5. The term 'physiology' is related to

• A. the Latin meaning of 'physical shape.'
• B. the structure of internal organs.
• C. the Greek for 'cutting up.'
• D. the Greek for 'relationship to nature.'

Correct answer: D

Rationale: The term 'physiology' originates from the Greek words 'physis' (meaning nature) and 'logos' (meaning study or relationship). Therefore, the correct answer is 'the Greek for 'relationship to nature.' Choice A is incorrect as it refers to the Latin meaning of 'physiology,' not the Greek origin. Choice B is incorrect as it is specific to the structure of internal organs, not the overall study of nature. Choice C is incorrect as it refers to a different term related to dissection or anatomy, not physiology.
