why intestine receives much more blood than the stomach ?
Answers
Answer:
Intestinal blood flow is critical for digestion, as well as being a key element of overall blood pressure control. During exercise and other environmental stresses, blood flow to the gut is restricted to allow maintenance of appropriate flows to the brain, heart, and skeletal muscles, for example.
Answer:
Intestinal blood flow accounts for 10–15% of the resting cardiac output (500–750 ml/min) in the adult human. There appears to be an oral-to-anal gradient in blood flow (milliliters per gram of tissue) along the small intestine. In the resting state, approximately 65% of the total intestinal blood flow is directed to the mucosa, 25% to the muscularis, and the remainder to the submucosa. This distribution of flow within the bowel wall is usually attributed to the greater metabolic demand of the mucosa. Stimulation of mucosal epithelial transport processes favors improved mucosal perfusion, whereas enhanced motor activity redistributes blood flow to the muscle layers
