! ultrafiltration Flashcards
1
Q
- the diameter of the efferent arteriole at the exit of the glomerulus is
A
smaller than the diameter of the afferent arteriole at the entrance causing a build up of pressure
2
Q
- the build up of pressure in the capillaries forms the
A
glomerulus
3
Q
- the pressure causes the smaller molecules being carried in the blood to be forced out of the capillaries and into
A
the bowman’s capsule
where they form the glomerular filtrate
4
Q
- small molecules like urea, glucose, amino acids, water and salts are forced
A
out the glomerulus into the bowmans capsule
5
Q
- larger molecules like proteins or red blood cells are
A
too big to fit across the capillary wall so they stay in the blood
6
Q
where is water reabsorbed
A
loop of henle & collecting duct
7
Q
where are salts reabsorbed
A
loop of henle
8
Q
where is glucose reabsorbed
A
proximal first convoluted
9
Q
where is urea reabsorbed
A
it is NOT reabsorbed
10
Q
what small molecules are pushed through
A
urea, glucose, amino acids, water and salts
11
Q
what large molecules are too big to go through so stay in the blood
A
proteins and red blood cells
12
Q
what makes up the glomerular filtrate
A
urea, glucose, amino acids, water and salts
