The difference between superficial and juxtamedullary nephrons is that superficial nephrons have their glomeruli in the cortex whereas the glomeruli of juxtamedullary nephrons are in the medulla. What percentage of the blood entering the kidney flows directly into the medulla without passing through the cortex?

Substance T is present in the urine. Does this prove that it entered the renal tubule by filtration at the glomerulus? Substance V is not normally present in the urine. Does this mean that it does not enter the kidney at all in the blood , or is neither filtered nor secreted? How many cell plasma membrane barriers must it cross in order to move from the blood to outside the body? A substance is freely filtered. Does this mean that it is all filtered? If you immunologically labeled cells of the macula densa with label X, and labeled cells of the thick ascending limb with label Y, would you find labels X and Y in the cortex, medulla, or both?

Given the generalizations about transport events in the medulla secretion, reabsorption , can you say that blood flow into the medulla is in any way different in volume from blood flow out of the medulla? YY Defines renal blood flow, renal plasma flow, glomerular filtration rate, and filtration fraction and gives normal values.

YY States the formula relating flow, pressure, and resistance in an organ. YY Describes the relative resistances of the afferent arterioles and efferent arterioles. YY Describes the effects of changes in afferent and efferent arteriolar resistances on renal blood flow.

The student understands how glomerular filtrate is formed and the forces that determine its rate of formation. YY Describes how molecular size and electrical charge determine filterability of plasma solutes; states how protein binding of a low-molecular-weight substance influences its filterability.

YY States the formula for the determinants of glomerular filtration rate, and states,in qualitative terms, why the net filtration pressure is positive. YY Defines filtration coefficient and states how mesangial cells might alter the filtration coefficient; states the reason why glomerular filtration rate is so large relative to filtration across other capillaries in the body.

YY Describes how arterial pressure, afferent arteriolar resistance, and efferent arteriolar resistance influence glomerular capillary pressure.

YY Describes how changes in renal plasma flow influence average glomerular capillary oncotic pressure. The student understands the normal controls of renal blood flow and glomerular filtration rate.

YY States the Starling forces involved in capillary filtration. YY States how changes in each Starling force affect glomerular filtration rate. YY Defines autoregulation of renal blood flow and glomerular filtration rate.

YY Describes the myogenic and tubuloglomerular feedback mechanisms of autoregulation. All of this blood flows through glomeruli in the cortex. This medullary blood derives from juxtamedullary glomeruli that are situated near the corticomedullary border.

Consider some typical numbers. A normal hematocrit is 0. Typical renal blood flow RBF is 1. The renal plasma flow RPF 5 0.

The remaining mL passes via the efferent arterioles into the peritubular capillaries. The radii of arterioles are regulated by the state of contraction of the arteriolar smooth muscle. The presence of 2 two sets of arterioles afferent and efferent and 2 sets of capillaries glomerular and peritubular makes the vasculature of the cortex unusual. The vasculature of the medulla is even more unusual, but we concentrate on the cortex for now.

Normally, the resistances of the afferent and efferent arterioles are approximately equal and account for most of the total renal vascular resistance. Resistance in arteries preceding afferent arterioles ie, cortical radial arteries plays some role also, but we concentrate on the arterioles.

This fraction, if it exists at all, is small. The peritubular capillaries are downstream from the efferent arteriole and have a lower hydraulic pressure. Typical glomerular pressures are near 60 mm Hg in a normal unstressed individual, whereas peritubular pressures are closer to 20 mm Hg. Why not share! An annual anal Embed Size px.

The end of the loop of Henle contains cells of the macula densa, which senses or assays the sodium and chloride content of the lumen and generates signals that influence other aspects of renal function, specifically the renin-angiotensin system discussed in Chapter 7.

The cortical collecting tubule is where several 6—10 connecting tubules join to form 1 tubule. Cells of the cortical collecting tubule are strongly responsive to and are regulated by the hormones aldosterone and ADH. Aldosterone enhances sodium reabsorption and potassium secretion by this segment, and ADH enhances water reabsorption. The degree to which these processes are stimulated or not stimulated plays a major role in regulating the amount of solutes and water present in the final urine.

With large amounts of ADH present, most of the water remaining in the lumen is reabsorbed, leading to concentrated, low-volume urine. With little ADH present, most of the water passes on to the final urine, producing dilute, high-volume urine.

The medullary collecting tubule continues the functions of the cortical collecting tubule in salt and water reabsorption.

In addition, it plays a major role in regulating urea reabsorption and in acid-base balance secretion of protons or bicarbonate. KEY CONCEPTS One major function of the kidneys is to regulate excretion of substances at a rate that, on average, exactly balances their input into the body and, thereby, maintain total body homeostatic balance for many substances.

A second major function of the kidneys is to regulate blood volume, blood osmolarity, and total body sodium content in a way that determines average blood pressure. The working tissues of the kidney are divided into an outer cortex and inner medulla.

The cortex receives an enormous volume of blood that flows in series through glomerular capillaries and then peritubular capillaries, whereas blood flow to the medulla is highly restricted.

The renal handling of any substance is defined by its rate of filtration, reabsorption, secretion, and, in some cases, metabolism. Is the following statement true or false?
