15 Questions
Which process involves the movement of substances from the glomerulus into Bowman's space?
Glomerular Filtration
What is the term used for the movement of substances from peritubular capillaries to the tubular lumen?
Tubular Secretion
Which statement is true regarding glucose in renal processes?
Glucose is only reabsorbed and not secreted
What is the formula for calculating the amount excreted in urine?
Amount Filtered + Amount Secreted - Amount Reabsorbed
Toxins in renal processes are primarily subjected to which process?
Tubular Secretion
What happens to substance X in the kidney?
It is filtered into glomerular filtrate and excreted in urine without reabsorption
What is the effect of constriction of efferent arterioles on Glomerular Filtration Rate (GFR)?
Increase in Pgc, leading to an increase in GFR
What do glomerular capillaries lack compared to other capillaries?
Large proteins such as albumin and globulins
What determines the Glomerular Filtration Rate (GFR)?
Net filtration pressures, surface area for filtration, and membrane permeability
What can affect the mesangial cells surrounding glomerular capillaries?
Decreased surface area of the capillaries
What is the purpose of Tubular Reabsorption?
To return filtered substances back to the blood circulation
What is Filtered Load a measure of?
Total amount of any protein/non-protein substance filtered into Bowman's space
What is the primary function of Metabolism by renal tubular cells?
To metabolize and either remove or produce substances
Which pressure favors filtration within glomerular capillaries?
Hydrostatic Pressure
How does an increase in plasma protein concentration affect Glomerular Filtration Rate (GFR)?
Does not affect GFR
