Arteries are really important for keeping our blood pressure stable when we exercise. Here’s how they work:
Widening Blood Vessels: When we work out, our muscles release substances that make blood vessels widen. This means more blood can flow to those muscles, making it easier for them to work hard.
Pressure Sensors: There are special sensors in our neck and chest that notice when blood pressure changes. When they detect a change, they send signals to the heart to pump faster and to help keep the blood pressure in a good range.
Increased Blood Flow: During intense exercise, blood flow to our active muscles can go up a lot—up to 20 times more! Even with this increase, our average blood pressure stays around 93 mmHg, which is pretty stable.
Less Resistance: As we exercise, the resistance in our blood vessels goes down because they widen. This helps blood flow to the muscles that need it, while the walls of the arteries remain strong and flexible.
In summary, our arteries have some special ways to help keep our blood pressure just right when we’re being active!
