|
Afferent arteriole
|
carries blood to glomerulus
|
|
|
Glomerulus
|
a tuft of capillaries that filters a protein-free plasma into the tubular component
|
|
|
efferent arteriole
|
carries blood from the glomerulus
|
|
|
peritubular capillaries
|
supply the renal tissue; involved in exchanges with fluid in the tubular lumen
|
|
|
justaglomerular apparatus
|
produces substances involved in the control of kidney function.
|
|
|
bowman's capsule
|
collects glomerular filtrate
|
|
|
proximal tubule
|
uncontrolled reabsorption an secretion of selected substances occurs here
|
|
|
loop of henle
|
establishes an osmotic gradient in the renal medulla that is important in the kidney's ability to produce urine of varying concentration
|
|
|
distal tubule and collecting duct
|
variable, controlled reabsorption of Na+ and water and secretion of K+ and H+ occur here; fluid leaving the collecting duct is urine, which enters the renal pelvis
|
|
|
Glomerular Filtration
|
nondiscriminant filtration of protein-free plasma from the glomerulus into bowman's capsule
|
|
|
Tubular Reabsorption
|
selective movement of filtered substances from the tubular lumen into the peritubular capillaries
|
|
|
Tubular Secretion
|
Selective movement of nonfiltered substances from the peritubular capillaries into the tubular lumen
|
|
|
glomerular capillary blood pressure
|
fluid pressure exerted by the blood within the glomerular capillaries
|
|
|
plasma-colloid osmotic pressure
|
caused by the unequal distribution of plasma proteins across the glomerular membrane
|
|
|
bowman's capsule hydrostatic pressure
|
the pressure exerted by fluid in this initial part of the tubule
