Multiple Choice Questions About Respiratory System Questions
Question 1 of 5

Correct Answer: C
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 2 of 5

Question 3 of 5
Wall of Larynx is supported by the cartilage
Correct Answer: D
Rationale: The correct answer is D, All these. The wall of the larynx is supported by a combination of cartilages, including the cricoid, thyroid, and arytenoid cartilages. The cricoid cartilage forms the base of the larynx, the thyroid cartilage forms the front and sides, and the arytenoid cartilages sit on top of the cricoid and are involved in vocal cord movement. Each of these cartilages plays a crucial role in supporting and maintaining the structure and function of the larynx. Therefore, all of these cartilages collectively support the wall of the larynx. Choices A, B, and C are incorrect because each of these cartilages individually contributes to the support of the larynx, but it is the combination of all three that fully supports the wall of the larynx.
Question 4 of 5
Bohr effect shifts the O2 Hb dissociation curve to right
Correct Answer: D
Rationale: The Bohr effect states that a decrease in pH shifts the oxygen-hemoglobin dissociation curve to the right, promoting the release of oxygen to tissues. This occurs in metabolically active tissues where CO2 is produced, lowering the pH. Choice D is correct because a decrease in blood pH facilitates oxygen unloading. Choices A and B are incorrect because the Bohr effect is related to oxygen release, not uptake. Choice C is incorrect because decreasing CO2 concentration would actually shift the curve to the left.
Question 5 of 5
Pinnaglobin is a brown coloured blood pigment present in the plasma of the mollusk Pinna. It contains
Correct Answer: B
Rationale: The correct answer is B: Copper. Pinnaglobin is a copper-containing blood pigment found in the plasma of the mollusk Pinna. Copper ions are essential for the formation of this pigment. Iron (Choice A), Manganese (Choice C), and Vanadium (Choice D) are not typically found in Pinnaglobin. Iron is commonly associated with hemoglobin in vertebrates, while manganese and vanadium do not play a significant role in mollusk blood pigments. Therefore, the presence of copper in Pinnaglobin makes Choice B the correct answer.
