During running, more blood goes to muscles and less to the digestive system. This is linked with which condition?
Answer and explanation
Correct answer: Body preparation for an emergency
Running demands immediate energy and oxygen from skeletal muscles. The sympathetic response and adrenaline increase heart activity and redirect a greater share of blood toward working muscles, while digestive activity is temporarily reduced. This prepares the body for rapid action, often called the fight-or-flight response. Therefore option A is correct; sleep, hydrotropism, and thyroid enlargement do not explain this blood-flow redistribution.
