Make a sketch of ONE complete Nephron in the kidney and label to show the blood flow (mark with red) and urine flow in this nephron (you can also use arrow to indicate flow direction). Remember only ONE nephron in your kidney. show the correct location of this nephron (Cortical vs. Juxtamedullary Nephrons) in the entire kidney. show the correct blood tubings within the nephron (I should be able to tell afferent and efferent arteriole from your sketch; also your nephron is closely associated with two capillary bed )
Pressure in the renal artery is 100 mm Hg and the pressure in the renal vein is 50 mm Hg. The resistance of the afferent arteriole equals 0.5 mm Hg•min/L and the resistance of the efferent arteriole equals 0.5 mm Hg•min/L. What is the pressure in the glomerulus?
IV. Nephron Blood Supply To understand the blood supply more clearly to nephrons, color the structures in the following figure. Use the suggested colors. Afferent arteriole: Pink • Efferent arteriole: Light red Glomerulus capillaries: Orange • Peritubular capillaries: Dark red • Veins that feed into renal vein: Blue Next, draw arrows to show the direction of blood flow. Also, label the following structures: • Proximal convoluted tubule • Distal convoluted tubule • Loop of Henle • Collecting duct
Draw a schematic diagram showing the flow of water and salts in the proximal tubule of the kidney. In this diagram, put the lumen on the left side of the diagram and the extracellular fluids on the right side of the diagram. Indicate where the lumen is, where the extracellular fluid is, where the apical portion of the cell is, and show the location of the proteins that are responsible for the movement of water and salts and glucose reabsorption in this area of the kidney
A patient comes to your medical practice with complaints of low urine output (not peeing). You use inulin to calculate the glomerular filtration rate (GFR) using the following information: Plasma level (P – constant over 24 hours): 10 mg/mL inulin. Urine sample (U): 144 mg inulin/mL urine. Urine formation (V): 10 mL/min. Using the fromula GFR=V ✕ U/P, you calculate a GFR of ... A) 144mL/min.. B) 14400 mL/min. C) 144 min./mL. D) 144 g mannitol/min.
Indicate which of the following is (are) being described: question 1 has 2 answers and question 4 also has 2 answers please answer angiotensisn II, aldosterone and/or ADH 1.increases blood pressure by direct vasoconstriction (2 ANSWERS) 2.stimulates insertion of aquaporins into the collecting duct (1 ANSWER) 3.increases the secretion of the other two (1 ANSWER) 4.acts on the principal cells of the nephron (2 ANSWERS) 5.increases Na+ reabsorption by the kidney (1 ANSWER) 6.has its production directly blocked by ACE inhibitors (1 ANSWER) 7.increases water reabsorption by acting on kidney collecting duct (1 ANSWER)
Number the following structures to indicate their respective positions in the blood pathway within the kidney. Assign the number 1 to the vessel nearest the abdominal aorta. Afferent arteriole Arcuate artery Arcuate vein Cortical radiate artery Cortical radiate vein Efferent arteriole Glomerulus Interlobular artery Interlobular vein Peritubular capillary (or vasa recta) Renal artery Renal vein Segmental artery
Explain the role of renin-angiotensin - aldosterone pathway in restoring blood pressure and fluid balance. Include the stimulus for release, the pathway that is involved, and the physiological effects of angiotensin II and aldosterone. Answer should include: Identify stimulus/change that starts the pathway (i.e. Identify the direction of change IN BP or circulating fluid status) What happens in the juxtaglomerular cells? Clue: what stimulus causes the release of renin? Explain action of renin - what protein does it act on? What is it converted to? Which enzymes converts angiotensin 1 to angiotensin 2? What are the actions of angiotensin 2? Clue: stimulates adrenal context to produce what? And what effect does angiotensin 2 have on blood vessels? What causes reabsorption of Na into blood ? What effect does this have on blood volume? How is BP restored ? Explain how this relates to equation for BP ( BP= CO x TPR)
Label the simple columnar epithelium of kidney tubule under HPO with the following: interlobular duct, nucleus, cell membrane, cytoplasm, basal lamina and lumen.
Most of the glucose that crosses the filtration barrier is absorbed in which of the following lettered regions on the light micrographs of the kidney ?
Given: Inulin is freely filtered in the glomerulus and not secreted nor reabsorbed in any appreciable amount at the nephron. If the concentration of inulin in the urine is 20 mg/mL, the concentration in blood plasma is 0.2 mg/mL plasma, and the rate of urine flow is 1 mL/min. a. What is GFR for this person? (Answer part a)
Maria is 8 months pregnant. When she goes to her doctor for her checkup, the nurse takes her blood pressure. It is unusually high: 200/100 mm Hg. The nurse also collects a urine sample and detects elevated levels of protein in her urine.What do you think has happened to her urine production? (Consider the pressures involved in determining net filtration pressure and osmotic force generated by solutes in the filtrate.) a. Urine production has stayed the same. b. Urine production has increased. c. Urine production has decreased. d. It is not possible to predict the effect on urine production.
