Determinants of renal blood flow

Renal blood flow % of CO
20%
Pressure in renal arteries

Renal capillaries properties
- Highly fenestrated capillaries have a high degree of permeability
- Two distinctly different capillary beds arranged in series
Distinct capillary beds of the renal system
- Glomerular capillaries
- Peritubular capillaries
Glomerular capillaries function
Filtration
PEritubular capillaries function
Reabsorption
Juxtoglomerular cells location
- Afferent arteriole
- abut closely to the distal tubule
Identify


Juxtaglomerular cells structure
Modified smooth muscle cells
Juxtaglomerular cells function
Produce and secrete renin
Identify


Identify


Vasa Recta Capillaries function
- Supply medullary blood flow
- maintain concentration gradient in the renal medulla
- Delivers nutrients
Vasa Recta Capillaries location
Form long loops paralleling loops of Henle
