Nephroptsosis Correct Answer Floating kidneys, the kidney slips from its normal position The Nephrons Correct Answer Functional unit of the kidney, site of filtration, secretion and reabsortion Glomerular filtration Correct Answer Water and most solutes in blood plasma move across the wall of the Glomerular capillaries and are filtered and move through the Glomerular capsule and into the renal tubule Tubular reabsortion Correct Answer The filtered fluid moves along the renal tubule and collecting ducts and tubule cells reabsorb water and many useful solutes, this flow back through the peritubular capillaries and vasa recta Tubular secretion Correct Answer Filtered fluid flows through the renal tubes and collecting ducts the renal tubule and duct cells secrete materials such as wastes, drugs, excess ions into fluid Edema Correct Answer Loss of plasma proteins in urine, an abnormally high volume of interstitial fluid Glomerular filtration rate (GFR) Correct Answer The amount of filtrate formed in all renal corpuscles of both kidneys each minute Myogenic mechanism Correct Answer Decreases GFR, an increase in stretching of smooth muscle in afferent arteriole walls (increase BP), causes the stretched smooth muscle fibers to contract and narrrow lumen of afferent arterioles Tubuloglomerular feedback Correct Answer Decreases GFR, increase deliver of Na and Cl due to high BP causes a decreased release of Nitric oxide (NO) and a contraction of afferent arterioles Neural regulation of GFR Correct Answer Decrease in GFR, an increase of activity level in sympathetic nerves releases norepinephrine and causes a constriction of afferent arterioles and an increase of renin
