Angiotensin II is a potent vasoconstrictor that increases blood pressure, not lowers it.

It constricts arterioles in the kidney, which helps maintain glomerular filtration rate (GFR).

It stimulates the cells of the proximal convoluted tubule (PCT) to enhance the reabsorption of sodium, chloride, and water.

It also stimulates the adrenal cortex to release aldosterone, which further promotes sodium and water reabsorption in the distal parts of the nephron, thereby increasing blood volume and blood pressure.

Therefore, lowering blood pressure is not a function of Angiotensin II.

Answer: It lowers blood pressure.
