The correct Answer is:
To solve the question, we need to analyze both the assertion and the reason provided. ### Step-by-Step Solution: 1. **Understanding the Assertion**: - The assertion states that "ADH and RAAS work in response to low blood volume and blood pressure." - **ADH (Antidiuretic Hormone)**: This hormone is released when the body detects low blood volume or low blood pressure. It acts primarily on the kidneys to promote water reabsorption, which helps to increase blood volume and pressure. - **RAAS (Renin-Angiotensin-Aldosterone System)**: This system is activated in response to low blood volume and blood pressure as well. It helps to increase blood pressure through vasoconstriction and by promoting sodium and water reabsorption in the kidneys. **Conclusion**: The assertion is true. 2. **Understanding the Reason**: - The reason states that "ANF works in response to high blood volume and blood pressure." - **ANF (Atrial Natriuretic Factor)**: This hormone is released by the heart when there is an increase in blood volume and pressure. Its primary function is to promote the excretion of sodium and water, which helps to reduce blood volume and pressure. **Conclusion**: The reason is also true. 3. **Evaluating the Relationship**: - The assertion is about the functions of ADH and RAAS in response to low blood volume and pressure. - The reason discusses the function of ANF in response to high blood volume and pressure. - While both statements are true, the reason does not explain the assertion. The assertion is focused on mechanisms that increase blood volume and pressure, while the reason describes a mechanism that decreases blood volume and pressure. 4. **Final Answer**: - Since both the assertion and reason are true, but the reason does not explain the assertion, the correct option is (b) both are true but reason is not correct explanation.
