Which of the following does not affect filtration rate? Select one: a. All the options alter filtration rate b. Atrial natriuretic peptide c. Renin d. Angiotensin II Micturition is another term for urination or expelling urine from the urinary bladder. The urge to urinate usually begins when the bladder contains 150 mL of urine and the sensation of fullness intensifies as urine volume increases to 300mL or more. Contractions also occur as the volume increases to 300mL or more. T/F The internal urethral sphincter is voluntary in its actions while the external urethral sphincter is involuntary. Select one: True False

Arteriole radius increases; the glomerular capillary pressure A) As the afferent resulting in an increase in glomerular filtration rate; arteriole radius remains constant; what happens to glomerular B) If the afferent and efferent filtration rate when you exercise? decrease C) If the efferent radius decreased, the glomerular capillary pressure will result in a decrease in glomerular filtration rate: Question 8 C) Diuretics [ Select ] urine output thus [ Select ] blood volume and therefore [ Select ] blood pressure: D) Your patient's filtrate concentration inside the nephron before entering the loop of Henle is 300 mOsm. Because your patient eats a lot of Nacho Doritos, her interstitium concentration around the loop of Henle is 900 mOsm. Your patient's urine concentration is [ Select ] and her urine volume is [ Select ] when compared to reference.

Urinary System: Glomerular Filtration 1. What force drives filtration at the glomerulus? ____________________ 2. Glomerular filtration is a process of ___________________ driven by the _____________________________ of the blood. 3. Common components of the filtrate are divided into four categories on the CD program. These include: 1) ____________________ 2) ____________________ 3) ____________________ 4) ____________________ 4. Blood pressure in the glomerulus is about _____ mmHg. 5. What two pressures oppose filtration and what are their values? 1) _______________________________________ 2) _______________________________________ 6. What is the normal net filtration pressure? _____ mmHg 7. With a glomerular filtration rate of 125 ml/min, how much plasma would be filtered per day? _____ In 24 hours? _____ 8. In an exercising individual, the afferent arteriole will (dilate or constrict) to avoid excess fluid loss. 9. Two mechanisms that provide autoregulatory control over renal processes include: 1) __________________________________________________________ 2) __________________________________________________________ 10. High osmolarity (or high Na+ and Cl-) in the ascending loop of Henle will cause afferent arterioles to (dilate or constrict) by releasing ________________________. 11. In periods of extreme stress, the sympathetic nervous system will override autoregulation. An increase in sympathetic flow to the kidney will result in what two important effects that will aid maintenance of blood pressure? 1) ________________________________________________________ 2) ________________________________________________________
