- In glomeruli, the efferent arteriole is usually smaller than the afferent? True Falsearrow_forwardTrue or false All chemicals in the glomerular capillaries are filtered into the nephron. Chemicals move from the glomerular caspule directly to the distal convoluted tubule of a nephron.arrow_forwardA 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.arrow_forward
- The most commonly used test for glomerular filtration. Gold standard test for glomerular filtration. It is a measure of the 24-hour urine collection.arrow_forwardin addition to BUN and creatinine indicators, an additional measure involves the glomerular filtration rate (GFR). Explain how each of these measures can be an indicator of kidney health and why it is important to assess for iodine-based contrast studiesarrow_forwardUrine dilution by the loop of Henle is dependent on the length of the loop, being more diluted, the longer the loop. True or falsearrow_forward
- Which glomerular arteriole is larger, and why? the efferent, because it increases hydrostatic pressure in the glomerulus the efferent, because it increases colloid oncotic pressure in the glomerulus the afferent, because it increases hydrostatic pressure in the glomerulus the afferent, because it increases colloid oncotic pressure in the glomerulusarrow_forwardUrinalysis demonstration [Video]. YouTube. Available at https://youtu.be/H0-EMmG3arc Answer the following questions: a. What happens with untreated UTI’s? b. What complications are there, if any, from only using herbal treatments? c. What percentage of males vs. females suffer from UTI’s?arrow_forwardWhich of the following would cause an increase in GFR? efferent ateriole constriction constriction of ureter afferent arteriole constriction increase in plasma protein concentrationarrow_forward
- The fenestrations of the glomerular capillaries allow all blood components except blood cells to pass through True Falsearrow_forwardIs this statement true or false: The juxtagomerular apparatus also pays a role in controlling the net glomerular filtration rate. If the GFR is high macula densa cells detect increase blood pressure. These cells respond by decreasing releasing of water which results in vasoconstriction of afferent. This decreases the GFR.arrow_forwardMost sodium reabsorption occurs in the __________ portion of the renal tubule.arrow_forward
