Sample text

Each vascular bed determines its own blood flow, with few exceptions (the skin and most notably the pulmonary circulation). This is based on the fact that most vascular beds change their vascular resistance to regulate flow through the organ. If there is increasing metabolic demand by an organ, flow increases to meet this demand, venous return from the organ increases, and in turn venous return to the heart increases. Thus cardiac output is the sum of the flow through individual autoregulating vascular beds that are all determining their own flow in independent fashion.

145 The organs most frequently cited as demonstrating autoregulatory activity include the brain, myocardium, kidneys, and retina. These are “survival organs,” essential for the stress response. Beyond autoregulation, there are other local influences that augment regional blood flow during increased metabolic activity or cardiac output. FIGURE 2-19 The generalized autoregulatory curve of flow (Q) versus pressure. Flow remains constant over a wide range of perfusion pressures (from 50 to 150 mm Hg in an adult vascular bed shown here).

Its actions include neurotransmission, relaxation of vascular smooth muscle contractile mechanisms, inhibition of platelet aggregation (and possibly prostaglandin synthesis), and complex chemical interactions with free radicals. Each of these actions may be involved in vascular regulation. Multiple isoforms of nitric oxide synthase (NOS) have been identified. Constitutive NOS is constantly present and probably involved in vascular regulation on a minute-to-minute basis in many microcirculatory beds.
