Paired organs, such as the kidneys or lungs, are said to be
- A. bisexual.
- B. bilingual.
- C. bilateral.
- D. bivalent.
Correct Answer: C
Rationale: The correct answer is C: 'bilateral.' Paired organs like the kidneys or lungs are described as bilateral because they occur in pairs on both sides of the body. Option A 'bisexual' refers to having both male and female reproductive organs, which is not the correct term for paired organs. Option B 'bilingual' refers to being able to speak two languages, which is not related to the description of paired organs. Option D 'bivalent' means having two valences, which is also unrelated to the context of paired organs.

The removal of wastes produced by metabolic reactions is
- A. metabolism.
- B. absorption.
- C. assimilation.
- D. excretion.
Correct Answer: D.
Rationale: The correct answer is 'excretion.' Excretion is the process of eliminating waste products produced by metabolic reactions from the body. Metabolism (Choice A) refers to the chemical processes that occur within a living organism to maintain life. Absorption (Choice B) is the process of taking in nutrients and fluids into the body. Assimilation (Choice C) is the process of absorbing and incorporating nutrients into the body after digestion. Therefore, excretion is the most appropriate term for the removal of metabolic wastes.
Absorption is the ability to exhale carbon dioxide.
- A. TRUE
- B. FALSE
- C. Not Sure
- D. None of the above
Correct Answer: B
Rationale: Absorption is the process of taking in substances such as nutrients or gases. Exhaling carbon dioxide is a part of the process of respiration, not absorption. Therefore, the statement that absorption is the ability to exhale carbon dioxide is false. Choice A is incorrect because absorption does not involve exhaling carbon dioxide. Choice C is incorrect as the concept of absorption can be clearly defined. Choice D is also incorrect as there is a definitive answer to the statement provided.
Metabolism is defined as _____.
- A. the removal of wastes produced by chemical reactions
- B. the breakdown of substances into simpler forms
- C. the taking in of nutrients
- D. all the chemical reactions occurring in an organism that support life
Correct Answer: D
Rationale: Metabolism refers to all the chemical reactions that take place within an organism to sustain life, including processes such as breaking down molecules, building new molecules, and energy production. Choice A is incorrect because it describes excretion rather than metabolism. Choice B is incorrect as it specifically refers to the breakdown of substances, not encompassing the entirety of metabolic processes. Choice C is incorrect as it focuses solely on nutrient intake, which is just one aspect of metabolism.
Which of the following organs is in the abdominopelvic cavity?
- A. The heart
- B. The trachea
- C. The thymus
- D. The liver
Correct Answer: D
Rationale: The correct answer is the liver. The liver is located in the abdominopelvic cavity, which is the space between the diaphragm and the pelvic floor. The heart, trachea, and thymus are not located in the abdominopelvic cavity. The heart is situated in the thoracic cavity, the trachea is in the neck region, and the thymus is located in the upper chest. Understanding the anatomical locations of organs is crucial for medical professionals to accurately diagnose and treat patients.
Is the parietal pericardium attached to the surface of the heart?
- A. TRUE
- B. FALSE
- C. Not Sure
- D. None of the above
Correct Answer: A
Rationale: The parietal pericardium is a tough, fibrous outer layer that is attached to the diaphragm and the sternum but not directly to the surface of the heart. It forms a sac around the heart known as the pericardial sac. Therefore, the statement that the parietal pericardium is attached to the surface of the heart is false.
