May indicate protective beta-adrenergic dilation in muscle during hemorrhage; leaves open relevance to human hypovolemic shock.
During hemorrhage, blood-borne catecholamines cause a significant beta-adrenergic dilator response in skeletal muscle resistance vessels that counteracts the constrictor response, likely to maintain nutritional blood flow.
Hillman et al. (1980) studied this question.
