Metabolic autoregulation, flow autoregulation, myogenic autoregulation
No parasympathetic innervation of arterioles!Importance of sympathetic “tone.”
Figure 12.02Capillaries
Capillaries = 5% of Blood Volume
Veins = 60% of Blood Volume
Arteries = 10 % of Blood Volume

Ex: brain and liver

Main difference in the Pulmonary circuit?
Net filtration = 4L/day
Bulk Flow through aqueous channels and intracellular clefts
Regulated by arterioles
