Question 1

Urine!

Question 2

Darker pee, means your body is

Answer 2

holding on to water

Question 3

the Nephron

Question 4

dialysis body cant release water, the process stops overhydration

Question 5

Peritubular capillaries

Question 6

Basic Renal Processes

Answer 6

Glomerular Filtration
Tubular Reabsorption
Tubular Secretion
Excretion

Question 7

There’s a large portion of your plasma that never makes it to Bowmans capsule

Answer 7

true

Question 8

4 forces that determine glomerular filtration pressure (GFP).

Answer 8

Bowman’s capsule hydrostatic pressure.
Glomerular capillary hydrostatic pressure.
Glomerular capillary osmotic pressure.
Bowman’s capsule osmotic pressure.

Question 9

Glom Filtration pressure

Answer 9

(P gc + pi bc) - (P bc + pi gc)
(60 mmHg + 0 mmHg) - (15 mmHg + 29 mmHg) = 16 mmhg

Question 10

Glomerular Filtration Rate (GFR) and Filtration Fraction

Question 11

Glomerular Filtration Rate GFR

Answer 11

typical RPF 625ml/min
plasma flow 125ml/min

Question 12

Kidney function has a sweet spot for GFR
80-180 mmHg

Answer 12

regulated by hormones and blood pressure

Question 13

Why is the GFR not linear

Question 14

Determine the filtration fraction and the filtered load (mg/min) for sodium given the following information: renal blood flow = 1.25 liters / min; hematocrit = 40; plasma sodium concentration = 140 mM; MW of sodium = 23; GFR = 125 mL/min.?

Answer 14

0.17

Question 15

Determine the filtration fraction and the filtered load (mg/min) for sodium given the following information: renal blood flow = 1.25 liters / min; hematocrit = 40; plasma sodium concentration = 140 mM; MW of sodium = 23; GFR = 125 mL/min. What is the filtered load?

Question 16

Tubular maximum, why does reabsorbtion flatline?

Answer 16

absorption can only work so hard.
