1. What presents the correct order of cellular respiration?

Correct answer: A

Rationale: The correct order of cellular respiration is Glycolysis, Acetyl-CoA, Citric Acid Cycle, and Electron Transport Chain. Glycolysis initiates the breakdown of glucose in the cytoplasm, leading to the formation of pyruvate. This pyruvate is then converted to Acetyl-CoA in the mitochondria, which enters the Citric Acid Cycle to generate energy-rich molecules like NADH and FADH2. Finally, the Electron Transport Chain, located in the inner mitochondrial membrane, utilizes these energy carriers to produce ATP through oxidative phosphorylation. Choice B is incorrect because it starts with the Citric Acid Cycle, which comes after Glycolysis. Choice C is incorrect as it places the Citric Acid Cycle before the Electron Transport Chain. Choice D is incorrect by placing Acetyl-CoA last instead of before the Citric Acid Cycle.

2. Which term refers to the space where lymph flows through the body?

Correct answer: C

Rationale: The correct answer is C: Interstitial space. This term specifically refers to the area where lymph flows between tissues. Lymph does not flow through arteries (choice A) or veins (choice D) as these vessels carry blood. The term 'lumen' (choice B) refers to the inside space of a tubular structure, like a blood vessel, but it does not specifically denote the space where lymph flows through the body.

3. He had to fill out a health history ____ before seeing the doctor.

Correct answer: A

Rationale: The correct answer is 'questionnaire.' A questionnaire is a set of questions used for gathering information. The incorrect choices B, C, and D have misspellings of the word 'questionnaire.' 'Questionaire,' 'questionnare,' and 'questionairre' are not correct spellings and may lead to confusion or misunderstanding. It is essential to use the correct spelling to ensure clear communication in healthcare settings.

4. What happens during expiration?

Correct answer: B

Rationale: The correct answer is B. During expiration, the diaphragm relaxes, causing the thoracic cavity to contract. As the thoracic cavity decreases in size, the pressure inside the lungs increases, leading to air flowing out of the lungs. This process helps to expel carbon dioxide-rich air from the body. Choices A, C, and D are incorrect. In choice A, the diaphragm contracting and the thoracic cavity expanding describes inspiration, not expiration. Choice C is incorrect because during expiration, the thoracic cavity actually decreases in size. Choice D is incorrect as the diaphragm moving upward is not a typical movement associated with expiration.

5. Which of the following is a condition characterized by inflammation and narrowing of the airways, leading to symptoms such as wheezing, coughing, and shortness of breath?

Correct answer: C

Rationale: Asthma is a chronic condition characterized by inflammation and narrowing of the airways, leading to symptoms such as wheezing, coughing, and shortness of breath. Pneumonia, caused by an infection in the lungs, presents with symptoms like fever, chills, and cough with sputum. Tuberculosis is a bacterial infection that primarily affects the lungs, leading to symptoms such as persistent cough, chest pain, and weight loss. Emphysema, a type of chronic obstructive pulmonary disease, is characterized by the destruction of the air sacs in the lungs, causing symptoms like shortness of breath and chronic cough. Therefore, among the options provided, asthma best fits the description of a condition with airway inflammation and narrowing.
