1
Q

What factors determine the filtration of a substance?

A

GFR
Volume of plasma moving into the nephron
Ion concentration

2
Q

Why isn’t there a Bowman’s osmotic pressure?

A

Protein should not be leaking into the glomerular capillaries

3
Q

What pressure is the primary regulator of of filtration?

A

Glomerular capillary hydrostatic pressure

4
Q

What is the term used when fluid is passed into the nephron?

A

Filtrate

5
Q

What portion of the nephron does ADH affect?

A

Distal tubule and collecting duct

6
Q

What pump creates the concentration gradient for sodium to move into the epithelial cell?

A

The Na/K atpase pump on the basal side of the cell

7
Q

What type of transport does glucose/amino acids used to get into the cells?

A

Secondary active transport, hitches a ride with sodium into the peritubular capillary

8
Q

What is the name of the peritubular capillaries in juxtamedullary nephrons?

A

Vasarecta, theses are important for concentrating urine
