At this point, we’ve seen the reabsorption of a great deal of water and nutrients back into the bloodstream, and filtrate content is more concentrated with products being removed from the body.Reabsorption of much of the remaining water and salt continues in the distal tubule, and it gets even more complex at this point due to an intricate regulating process involving sympathetic nerve impulses that constrict either the afferent or efferent arterioles, depending upon negative tubuloglomerular feedback regulating each individual nephron; this incredible feedback system isolates the absorption function from changes in systemic blood pressure, and controls the delivery of filtrate to the distal tubules by regulating the GFR.The loops, parti...
