Explanation:
Detailed explanation-1: -Blood pressure is the force of the blood pushing against the artery walls. The force is made with each heartbeat as blood is pumped from the heart into the blood vessels. This is called systolic blood pressure.
Detailed explanation-2: -Because the space in the arteries is narrower, the same amount of blood passing through them increases the blood pressure. Veins can constrict to reduce their capacity to hold blood, forcing more blood into the arteries. As a result, blood pressure increases.
