1. The renin and angiotensin systems help to maintain the balance of sodium and water in the body. What other functions do these systems serve?

Correct answer: B

Rationale: The correct answer is B: Maintaining a healthy blood volume. The renin and angiotensin systems not only help to regulate sodium and water balance in the body but also play a crucial role in maintaining an adequate blood volume. This is essential for normal blood pressure regulation and overall cardiovascular health. Choices A, C, and D are incorrect because hemoglobin levels are primarily regulated by the bone marrow and erythropoietin, platelets are released in response to blood vessel injury by a different mechanism, and the systems do not focus on lowering blood volumes but rather on maintaining them.
