Short Answer Questions from Practice Exam Flashcards
What are the three pressures that influence filtration
glomular hydrostatic, capsular hydrostatic, colloid osmotic
What pressures favor filtration
glomular hydrostatic
What pressures oppose filtration
colloid osmotic, capillary hydrostatic
How does ADH influence the concentration of urine
ADH increases the concentration because it promotes the reabsorption of water in the collecting duct due to aquaporins
What is pulled out in the descending loop and how
H2O is pulled out using the concurrent pressure mechanism
What is pulled out in the ascending loop
Na is pulled out using the concurrent pressure mechanism
What can be reabsorbed in the collecting duct
urea to increase osmotic pressure
If the afferent arteriole is constricted what happens
glomerular pressure decreases
How does the small intestine protect itself from acid
secretin neutralizes
What is the function of the renin-angiotensin mechanism
constrict arterioles to increase blood pressure
With the Boer effect more oxygen is released because
decrease in pH weakens hemoglobin oxygen bond
Malnutrition causes what in the kidneys
lack of proteins in the blood, decrease blood osmotic pressure, increase GFR
An increase in capsule hydrostatic pressure does what
decrease GFR
High ketone levels in the blood do what to inspiration
Increase it
A decrease is CO2 concentrations in the blood does what to inspiration
decreases it
