“Damaged kidney arteries don’t filter blood well. Kidneys have small, finger-like nephrons that filter your blood. Each nephron receives its blood supply through tiny hair-like capillaries, the smallest of all blood vessels. When the arteries become damaged, the nephrons don’t receive the essential oxygen and nutrients. Then the kidneys lose their ability to filter blood and regulate the fluid, hormones, acids and salts in the body. “
The analogy that the circulatory system is like a hydraulic sytem or oiling system is incorrect.
I’d say it is more like a chemical reaction catalytic system, where, if the converter substrate is damaged, (nephrons) the exhaust gases don’t get reacted properly.
Again: I agree damaged arteries are an issue. But there are other causes of high blood pressure. Are those other causes ALSO damaging to kidneys? If so, what is the evidence?
