Describe the changes in cardiac output and blood flow during exercise
What will be an ideal response?
During exercise, cardiac output increases, and blood flow to skeletal muscles increases at the expense of blood flow to less essential organs. Unless compensatory vasoconstriction occurs in "less essential" organs, such as those of the digestive system, vasodilation in skeletal muscles would cause a potentially dangerous decrease in blood pressure and blood flow throughout the body during exercise.
