where is the majority of the renin produced in the kidney
Renin The enzyme renin is secreted by pericytes (mural cells) (1) in vicinity of the afferent arterioles and similar microvessels of the kidney from specialized cells of the juxtaglomerular apparatusâ€”the juxtaglomerular cells, in response to three stimuli:
Pulse Pressure waves generated by the heart in systole move the arterial walls. Forward movement of blood occurs when the boundaries are pliable and compliant. These properties form enough to create a palpable pressure wave.
Small intestine Food from the stomach is allowed into the duodenum through the pylorus by a muscle called the pyloric sphincter.
