|
glomerulus
|
leaky capillaries with large capillary pores
|
|
|
Glomerulus capsule
|
where all components of blood, except cells and large proteins, are forced out of the capillaries by blood pressure
|
|
|
primary filtrate
|
1. fluid in glomerular capsule
2. identical chemical composition to blood plasma without the large proteins |
|
|
filtration
|
blood pressure drives convective flow through pores in glomerulus
|
|
|
Glomerular filtration rate (GFR)
|
total rate at which fluid passes through all the glomeruli in both kidneys, moving from blood into the proximal tubule.
|
|
|
afferent arterioles
|
1.lined with smooth muscle so they can vasodilate or constrict
2. dillation of afferent arterioles = increase in glomerular pressure and GFR, constriction does the opposite |
|
|
efferent arterioles
|
1. dilation of efferent arterioles = decrease in glomerular pressure and GFR, constriction does the opposite
|
|
|
afferent and efferent arterioles and GFR
|
relative constiction of the afferent and efferent arterioles provides a strong control on GFR and urine formation rate
|
|
|
drops in blood pressure within the kidney =
|
occurs in the arterioles
|
