Final answer:
The two types of renal auto regulation are the myogenic mechanism and the tubuloglomerular feedback mechanism. The myogenic mechanism involves the contraction and relaxation of the smooth muscle in the arterioles of the kidneys in response to changes in blood pressure. The tubuloglomerular feedback mechanism involves the communication between the cells of the juxtaglomerular apparatus (JGA) and the afferent arterioles.
Step-by-step explanation:
The two types of renal auto regulation are the myogenic mechanism and the tubuloglomerular feedback mechanism. The myogenic mechanism involves the contraction and relaxation of the smooth muscle in the arterioles of the kidneys in response to changes in blood pressure. When blood pressure increases, the arterioles constrict to prevent excessive blood flow, and when blood pressure decreases, they relax to allow for more blood flow.
The tubuloglomerular feedback mechanism involves the communication between the cells of the juxtaglomerular apparatus (JGA) and the afferent arterioles. When there is an increase in the flow rate of filtrate through the tubules, the JGA cells release a signaling molecule that causes the afferent arterioles to constrict, reducing blood flow and maintaining a constant filtration rate.
