What describes a short-term effect of exercise on the human body systems?

A short-term increase in blood flow during exercise is an essential response of the body. When an individual engages in physical activity, the heart pumps more blood to deliver oxygen and nutrients to the muscles that are actively working. This increased blood flow is crucial for enabling sustained muscular effort and enhancing performance. The body also redistributes blood flow, directing it away from non-essential areas to the muscles, skin, and heart, where it is most needed during exercise.

This physiological response highlights the adaptation mechanisms of the cardiovascular system in response to immediate demands placed on the body during activity. As a result, the heart rate increases, and blood vessels dilate to accommodate the heightened demand for oxygen and nutrient delivery, leading to the overall increase in blood flow to support the body's immediate energetic needs.
