Detailed explanation-1: -Your blood pressure is highest when your heart beats, pumping the blood. This is called systolic pressure.

Detailed explanation-2: -Each time the heart beats (contracts and relaxes), pressure is created inside the arteries. The pressure is greatest when blood is pumped out of the heart into the arteries. When the heart relaxes between beats (blood is not moving out of the heart), the pressure falls in the arteries.

Detailed explanation-3: -Which of the following occurs when the heart forcefully contracts? Increased blood pressure.

Detailed explanation-4: -The systolic blood pressure is defined as the maximum pressure experienced in the aorta when the heart contracts and ejects blood into the aorta from the left ventricle (approximately 120 mmHg).

Detailed explanation-5: -High blood pressure adds to your heart’s workload: Narrowed arteries that are less elastic make it more difficult for blood to travel efficiently throughout your body. This causes your heart to work harder.
