  • Gastrointestinal blood flow was measured from the *combined celiac and mesenteric (i.e. splanchnic), superior mesenteric artery, or celiac artery. For the Burmese python, postprandial and exercise, and postprandial cardiac output and gastrointestinal blood flow were measured at 5 days postfeeding.
