The total peripheral resistance refers to the total peripheral resistance of blood flow, and the sum of the total peripheral resistance of blood circulation is the total peripheral resistance. The total peripheral resistance of blood circulation is the sum of total peripheral resistance. The resistance of micro-arteries in the blood flow process accounts for nearly 50% of the total peripheral resistance, followed by capillaries. Sometimes when the whole body vasoconstriction, the total peripheral resistance will be higher, and blood pressure will also rise, when the whole body vasodilation total peripheral resistance will fall, blood pressure is also falling, total peripheral resistance is proportional to blood pressure, the total peripheral resistance reflects the blood pressure from the side. High total peripheral resistance reflects the presence of hardening of the arteries and is related to dietary habits, such as high intake of animal fat or lack of exercise.
