Renal Physiology

Front 1

Bulk Flow of protein-free plasma from the Glom. Capilaries into Bowman's Capsule

Back 1

Glomerular Filtration

Front 2

Selective transport ogf molecules from the lumen of renal tubules to the interstit. fluid outside the tubules.

Back 2

REABSORBTION

Front 3

Reabsorbed Molecules eventually enter the peritunular capilaries by_______?

Back 3

Diffusion

Front 4

Selective transport of molecules from the peritubular fluid to the lumen of the renal tubules.

Back 4

Secretion

Front 5

Where do the secreted molecules come from?

Back 5

Plasma of peritubular capillaries

Front 6

What is the beginning of the renal tubule known as?

Back 6

Proximal Con. Tubule

Front 7

What does the oncotic pressure in Bowman's capsule favor?

Back 7

Filtration

Front 8

What drives glomerular pressure?

Back 8

Hydrostatic and Osmotic pressure existing across walls of glom. capillaries

Front 9

What does filtrate lack that plasma does not lack?

Back 9

Protein

Front 10

In the Boeman's Capsul, what acts as the primary filtration barrier for proteins?

Back 10

Basement membrane

Front 11

Filtrate must cross these three things
to enter Bowman's Capsule:

Back 11

1. Capillary Endothelial layer
2. Surounding epithelial cell layer
3. Basement Membrane(sandwiched between them)

Front 12

What are the three layers called that the filtrate must cross before entering the Bowman's capsule?

Back 12

Filtration Barrier or Glomerular
Membrane

Front 13

What does the high resistance of the efferent artiole account for?

Back 13

A lower the pressure downstream
