The mechanism for maintaining filtration rate in relation to blood pressure is carried out by the juxtaglomerular apparatus which is composed of the macula densa and the juxtaglomerular cells in the kidneys. When blood pressure drops, the juxtaglomerular apparatus secretes renin, which initiates the renin-angiotensin-aldosterone cycle that raises blood pressure.
