Question

How ADH increases blood pressure?

• A. Hyposecretion of ADH leads to low water absorption.
• B. Hypersecretion of ADH leads to low water absorption.
  
• C. Hyposecretion of ADH leads to higher water absorption.
• D. None of the above.

Answer 1

Answer: (B)

Hypersecretion of ADH leads to low water absorption.

ADH hormone is associated with water absorption by the kidney. Hyposecretion of ADH leads to low water absorption and volume of urine is increased. So the volume of blood will decrease and finally blood pressure will decrease. More ADH leads to increased blood volume and consequently high blood pressure. ADH is also related to vasoconstriction leading to high blood pressure.
