MICROANATOMY

Detailed explanation-1: -Healthy kidneys respond to a hormone called aldosterone which is produced in the adrenal glands, to help the body regulate blood pressure. Kidney damage and uncontrolled high blood pressure contribute to a negative spiral. As more arteries become blocked and stop functioning, the kidneys eventually fail.

Detailed explanation-2: -The kidneys help to control blood pressure by removing water and salt from the blood, as well as producing hormones that are involved in controlling blood pressure.

Detailed explanation-3: -Blood pressure is regulated in the body by changes to the diameters of blood vessels in response to changes in the cardiac output and stroke volume. Factors such as stress, nutrition, drugs, exercise, or disease can invoke changes in the diameters of the blood vessels, altering blood pressure.

Detailed explanation-4: -The renal arteries are part of the circulatory system. They carry large amounts of blood from the aorta (the heart’s main artery) to the kidneys. Approximately 1/2 cup of blood passes through your kidneys from the renal arteries every minute. Your kidneys are part of the urinary system.
