Blood pressure dynamic during exercise

## Step1: Understanding Blood Pressure
### Blood pressure is the force that your heart exerts against the walls of your arteries as it pumps blood. It is measured in millimeters of mercury (mm Hg) and is expressed as two numbers. The top (systolic) number represents the pressure in the arteries when the heart beats (when the heart muscle contracts), and the bottom (diastolic) number represents the pressure in the arteries when the heart is at rest (between beats).
## Step2: Understanding Exercise Impact on Blood Pressure
### During exercise, the body's demand for oxygen increases. To meet this demand, the heart pumps more blood with each beat, which increases the systolic blood pressure. However, the diastolic blood pressure may not change significantly or may even decrease slightly due to the arteries dilating to allow more blood to flow to the muscles.
## Step3: Understanding Pulse Pressure
### Pulse pressure is the difference between systolic and diastolic blood pressure. During exercise, as the systolic blood pressure increases and the diastolic blood pressure remains the same or decreases slightly, the pulse pressure widens.
