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 )
The Nephron Identify the structures of the nephron by coloring them as described here. Insert arrows to show V. the direction of flow. Afferent arteriole: Dark red • Efferent arteriole: Blue • Proximal convoluted tubule: Pink • Descending limb of loop of Henle: Green • Ascending limb of loop of Henle: Purple Distal convoluted tubule: Orange • Collecting duct: Yellow • Outline Bowman's capsule in brown • Glomerulus: Light red
Explain the anatomical concepts associated with the urinary system. Summarize this module’s key points in 5-6 sentences. Explain the physiological concepts associated with the urinary system. Summarize this module’s key points in 5-6 sentences. How will you apply the concepts you have learned about with the urinary system in real life and in your future career
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
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
Using the space below, DRAW a simple diagram of the nephron loop and the vasa recta capillaries. Include the following in your drawing: Arrows showing the direction of blood flow in the vasa recta and the flow of tubular fluid (pre-urine) in the nephron loop An arrow (labeled # 1) showing where NaCl is pumped out of the nephron loop An arrow (labeled #2) showing where NaCl diffuses into the vasa recta An arrow (labeled #3) showing where NaCl diffuses out of the vasa recta An arrow (labeled #4) showing where water diffuses out of the nephron loop 10 good Nephrahtcop, is eirlu Vasa Recta astagi lls zirds gnidu dol bemot etsult ai s1erW I o e brus noltqroeds91 Jzom 25ob sedW Tuppo Jolb bns eenomad oe ni bns noit qroadsen isnolilbbe seob o1arW Ihshiavollanid Lbeninm baildsten ai notteineonoo muiboz s al e holde 10 nobqoedes gnihub sludu i6n91 erb lo mutioriqe ardd za010 29onsiedue ob woH .e
Describe the functions of the urinary system. Identify the 4 organs of the urinary system. What is a nephron? Describe the gross anatomy of the kidneys Trace the blood flow (listed vessels only) from Abdominal Aorta to Inferior Vena cava. Describe the structure of the Glomerulus (Renal Corpuscle). Trace the flow of filtrate through the nephron. Identify which nephron parts are in the cortex and which are in the medulla of kidney. Describe the anatomy (layers and tissues) and the functions of the ureter, urinary bladder, and the urethra. Describe the following nephron functions and identify the specific nephron structures where these processes occur. Filtration – Reabsorption – Secretion - Identify the specific structure in the nephron and the process that occurs for each listed substance: Process: filtered, not filtered, reabsorbed, secreted. Substances = water, Na+, K+, H+, Bicarbonate (HCO3-), Cl-, Ca2+, urea, ammonia (NH3 or NH4+), glucose, protein, amino…
Direction: Using the pictures below, explain the three-step process of how kidneys filter blood and form urine as a waste product. Proximal convoluted tubule Distal convoluted tubule incoming arteriole blood blood flow -outging arteriole enters - glomerulus -Bowman's capsule Glomerular filtration: Counter creates a plasma-like filtrate of the blood. current flow -Ascending limb Descending limb proximal tubule flow of nitrate H2O is diffused out by osmosis H20 is carried away by blood Part 2 Loop of henle Direction: Give the function of each component of a nephron Increasing concentration of tissue fluid
Draw the kidney identifying the following structures: Renal hilum Renal artery and vein Pelvis Ureter Major calyx Minor calyx Renal pyramids Arcuate vein and artery
Which type of nephron (juxtamedullary or cortical) does this setup appear to approximate? Hint: pay attention to mOsm Alcohol blocks ADH. What affect would this have on the volumes and concentrations of urine, tubular, and interstitial fluid?
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)
Match the structure of the nephron to its primary function. Renal corpuscle Proximal tubule Loop of Henle Distal tubule Collecting duct responsible for size-selective filtration of the blood responsible for active transport and reabsorption of ions and nutrients as well as the reabsorption of water may or may not reabsorb sodium ions depending on the presence or absence of the hormone aldosterone. establishes a strong osmotic gradient allowing the reabsorption of water, sodium ions, and chloride ions. regulates reabsorption of water in response to the presence of ADH & secretes urea into the interstitial fluid to maintain the osmotic gradient of the medulla.
