There is no relationship between blood pressure and height. Blood pressure is related to heart contractility, heart rate, peripheral resistance, blood vessel elasticity and blood volume.1. Blood pressure is the pressure of blood on the inner wall of blood vessels. When the heart’s contractility increases, the kinetic energy of the blood is large, and the pressure on blood vessels increases, resulting in high blood pressure. Increased heart rate is also an important factor affecting blood pressure, mainly affecting diastolic blood pressure. Blood vessel elasticity has a buffering effect on blood pressure. Large arteries can store a certain amount of blood due to their large volume, which can keep blood pressure from fluctuating drastically.2. Blood pressure is the driving force of blood circulation and the prerequisite to ensure that tissues and organs are nourished by blood. High blood pressure mainly damages vital organs such as the heart, the brain and the kidneys, while low blood pressure causes vital organs of the human body not to be adequately nourished by blood. However, both high and low blood pressure have nothing to do with height.
