Ch 12 Cardiovascular Physiology 5 November 2008 Sections C,D,E Not covering Section F Blood & Hemostasis Lab this Week: EKGs and Blood Pressure. Wear shoes and clothes for running. Abstract due Friday.
Fig Metabolic autoregulation, flow autoregulation, myogenic autoregulation No parasympathetic innervation of arterioles! Importance of sympathetic “tone.”
Figure Capillaries Capillaries = 5% of Blood Volume Veins = 60% of Blood Volume Arteries = 10 % of Blood Volume 4
Figure Continuous, discontinuous, and fenestrated capillaries: Ex: brain and liver 5
Diffusion, mediated transport, bulk flow 8
