Role of renin-angiotensin system in response to hemorrhage in fetal sheep.


During fetal life, the autonomic nervous system is not fully mature, and it is likely that hormonal mechanisms play an important role in controlling cardiovascular function. In chronically instrumented fetal sheep, hemorrhage increased plasma renin activity and plasma angiotensin concentration significantly from 6.7 +/- 2.5 to 15.2 +/- 3.1 and… (More)
