Answer:
adrenal cortex
Explanation:
Hypertension is the condition in which the blood pressure becomes very high. It can lead to other problems too like hyperaldosteronism. Adrenal cortex starts to produce excess aldosterone which increases sodium reabsorption and potassium excretion from the excretory system. This process decreases potassium level in blood. It also increases sodium level in blood which can ultimately increase the blood pressure more.
