High blood pressure occurs when there is too much blood flowing through the blood vessels at one time. by changing the amount of water in the blood, blood pressure can change. the excretory system can to lower blood pressure. which would most likely occur in the kidney? a)more water would be transferred from the nephron. b)less water would be absorbed into the nephron. c)the amount of water in the bladder would decrease. d)the amount of water in the blood would increase.

The correct answer is option B

Nephrons are the filtering units of Kidney and they filter waste out of blood along with water. When the water is less in the body , nephron filters reduces the water consumption and more concentrated waste is expelled out of the blood thereby maintaining the blood pressure.

The correct answer will be option-B

Explanation:

The kidney plays an important role in the regulation of arterial blood pressure by controlling the amount of water in the blood.

When arterial blood pressure increases in the body, kidney help maintain the blood pressure by releasing high amount of urine.

The water present in the blood is released through the urine which decreases the amount of water in the body. This helps in lowering the blood pressure.

Thus, Option-B is the correct answer.
