Question

Arteries adjust the amount of blood flowing to different parts of the body,depending on where blood is needed.Use this fact to explain why you should not exercise vigorously shortly after you eat.

Answer 1

When you eat, blood needs to be funneled to your stomach and intestines, and these arteries are widened. To exercise, more blood needs to be funneled to the area used in exercise, instead of to the stomach. Thus food will not get digested properly because the blood flow is moving toward the area utilized in exercise.
