In-Class Activity: Urine Formation- Step 1
1.) Urine formation involves 3 processes. List and describe these 3 processes.
2.) Net filtration pressure in the glomerulus is about +10 mmHg throughout the entire capillary bed. In what ways does the NFP of the glomerulus differ from the NFP of the systemic capillaries? Why is this significant?
3.) Define GFR. GFR is directly proportional to what 3 things?
4.) GFR can be entirely controlled just by changing 1 thing. What is that 1 variable?
5.) Explain renal autoregulation in your own words.
6.) How would giving a patient intravenous albumin affect filtration?
7.) What type of response by the afferent arterioles would you expect if blood pressure increased?
8.) When are autoregulatory mechanisms most effective?
9.) Extrinsic controls regulate glomerular filtration rate as a means of regulating ________________________.
10.) Name 2 substances that are NOT found in normal filtrate.
11.) Describe the mechanism of glomerular filtration that involves the macula densa cells.
