Questions About the Respiratory System Questions
Question 1 of 5
The nasal conchae epithelial surface serves to:
Correct Answer: D
Rationale: Rationale: The nasal conchae increase surface area, causing air turbulence to warm, moisten, and filter inhaled air. This helps in preventing respiratory issues. Choice A is correct as it explains the primary function of the conchae. Choice B is incorrect as the primary function is not filtering. Choice C is incorrect as the conchae primarily warm and moisten inhaled air rather than recapture moisture from exhaled air. Overall, choice D is correct as it encompasses all the functions of the nasal conchae.
Question 2 of 5
The effect of pH on hemoglobin saturation is known as the
Correct Answer: B
Rationale: The correct answer is B: Bohr effect. This effect describes how pH affects hemoglobin saturation. When pH decreases (becomes more acidic), hemoglobin's affinity for oxygen decreases, promoting oxygen unloading in tissues. This is due to the protonation of histidine residues in hemoglobin, altering its structure. The other choices are incorrect because the Bainbridge reflex is related to heart rate regulation in response to changes in blood volume, the pulmonary reflex relates to the regulation of breathing in response to changes in blood oxygen levels, and the respiratory effect is a general term that does not specifically describe the pH effect on hemoglobin saturation.
Question 3 of 5
One way to improve respiratory performance with age is to
Correct Answer: B
Rationale: The correct answer is B: stop smoking. Smoking can damage the lungs and reduce respiratory function. By quitting smoking, lung health can improve, leading to better respiratory performance with age. Eating smaller meals, sleeping longer, and maintaining normal glucose levels do not directly impact respiratory performance. Smoking cessation is the most effective way to improve lung function and overall respiratory health.
Question 4 of 5
What dietary recommendation is often given to heart failure patients to manage their condition?
Correct Answer: D
Rationale: The correct answer is D: Low-sodium diet. Sodium can exacerbate fluid retention in heart failure patients, leading to increased workload on the heart. A low-sodium diet helps reduce fluid retention and manage symptoms. High-sodium diet (A) is detrimental to heart failure patients. Low-fat diet (B) and low-sugar diet (C) may be beneficial for overall health but are not specific recommendations for managing heart failure.
Question 5 of 5
The left lung has two lobes and they are separated by Deep fissure called .
Correct Answer: B
Rationale: The correct answer is B: oblique fissure. The left lung has two lobes, the upper lobe and the lower lobe, which are separated by the oblique fissure. This fissure extends obliquely downward and forward from the posterior border of the lung. Rationale: 1. The horizontal fissure separates the right lung into upper and middle lobes, not the left lung. 2. There is no such structure as a vertical fissure in the human lung anatomy. 3. "Non of them" is grammatically incorrect and does not provide a valid option.
