choice1="The filtered fluid is essentially protein free."
 
choice2="There is a large amount of protein in the Bowman's space."
 
choice5="There is high hydrostatic pressure in the Bowman's space."

choice3="There is a large amount of protein reabsorbed in the nephron."
 
correctchoice="1"
 
feedback1="'''Correct!''' Most proteins are too large to be filtered and therefore remain in the glomerular capillary.

[[Glomerular Apparatus and Filtration - Anatomy & Physiology#Glomerular Filtration |WikiVet Article: glomerular filtration]]."
 
feedback2="'''Incorrect.''' Most proteins are too large to be filtered and therefore remain in the glomerular capillary. Large proteins are not filtered into Bowman's capsule unless a component of the filtration barrier (e.g. the glomerular basement membrane) is damaged in which case the oncotic pressure would be higher than zero. Oncotic pressure in the Bowman's capsule is normally zero because filtered fluid is essentially protein free. [[Glomerular Apparatus and Filtration - Anatomy & Physiology#Glomerular Filtration|WikiVet Article: glomerular filtration]]."
 
feedback5="'''Incorrect.''' There is high hydrostatic pressure in the capillaries causing filtration into the Bowman's space because there is low hydrostatic pressure in the Bowman's space.

feedback4="'''Incorrect.''' Hydrostatic pressure does not directly affect oncotic pressure. Most proteins are too large to be filtered and therefore remain in the glomerular capillary. Large proteins are not filtered into Bowman's capsule unless a component of the filtration barrier (e.g. the glomerular basement membrane) is damaged.

[[Glomerular Apparatus and Filtration - Anatomy & Physiology#Glomerular Filtration|WikiVet Article: glomerular filtration]]."
 
feedback3="'''Incorrect.''' Large amounts of protein are not capable of being reabsorbed from the nephron back into the blood. Most proteins are too large to be filtered and therefore remain in the glomerular capillary. Large proteins are not filtered into Bowman's capsule unless a component of the filtration barrier (e.g. the glomerular basement membrane) is damaged. Oncotic pressure in the Bowman's capsule is normally zero because filtered fluid is essentially protein free.
