Question 14

Baroreceptors are stretch receptors composed of fine branching nerve endings that are contained along the walls of the arteries near the heart and in other areas of the body.

This statement is not accurate as it misrepresents the information about baroreceptors by suggesting they are contained along the walls of arteries, whereas the passage indicates that they are located along these walls.

A) Baroreceptors are stretch receptors composed of fine branching nerve endings that are contained along the walls of the arteries near the heart and in other areas of the body.

This option is incorrect because it includes the term "contained," which implies a level of confinement that does not align with the passage's description. Baroreceptors are indeed located along the arterial walls but are not described as being "contained" in that manner.

B) Chemoreceptors are located along the walls of the arteries and monitor changes in oxygen level, carbon dioxide, and pH.

This statement is correct and accurately reflects the information from the passage. It identifies the location of chemoreceptors and their function in monitoring essential physiological parameters.

C) The kidneys play a role in regulating blood pressure by absorbing salts and water and removing wastes.

This statement is also correct. The passage explicitly describes the kidneys' function in blood pressure regulation, emphasizing their role in absorbing salts and water while eliminating waste.

D) The heart is the body's pump, which regulates the flow of vitally needed oxygen to all cells of the body.

This statement is correct as well. The passage highlights the heart's function as a pump that ensures the delivery of oxygen to cells and the removal of waste, reinforcing its critical role in the cardiovascular system.

Conclusion

Option A is definitively incorrect due to its misleading wording about the nature of baroreceptors. In contrast, options B, C, and D are accurate representations of the information provided in the passage. The core concept being tested here is the accuracy of details presented in the context of blood pressure regulation, and option A fails to adhere to this accuracy.
