Explanation: 

Detailed explanation-1: -The kidneys are two bean-shaped organs, each about the size of a fist. They are located just below the rib cage, one on each side of your spine. Healthy kidneys filter about a half cup of blood every minute, removing wastes and extra water to make urine.

Detailed explanation-2: -High blood pressure can constrict and narrow the blood vessels in your kidneys, which reduces blood flow and stops the kidneys from working well. When this happens, the kidneys are not able to remove all wastes and extra fluid from your body.

Detailed explanation-3: -The kidney is a filter. It filters blood to remove excess fluid and eliminate waste products. When the blood pressure is low, there is less blood flowing through the filters and hence less urine formation that results from those individual filters.

Detailed explanation-4: -Bowman’s capsule surrounds the glomerular capillary loops and participates in the filtration of blood from the glomerular capillaries. Bowman’s capsule also has a structural function and creates a urinary space through which filtrate can enter the nephron and pass to the proximal convoluted tubule.
