In the stomach and small bowel, a gram of mucosa receives a greater blood flow than does a gram of muscularis. This distribution difference has been ascribed to the secretory or absorptive function of the mucosa. The primary function of the esophagus is transport, a muscular activity. Using sr, RbCl and the indicator fractionation technique in anesthetized rats, we found that a gram of esophageal muscle receives nearly the same blood flow as a gram of esophageal mucosa. This more equal distribution of blood flow in the esophagus, compared to the distribution of flow to the mucosa and muscle of the stomach and small bowel, presumably reflects the different function of the esophagus.
