Cardiovascular system: the driving force of life flow

The cardiovascular system is the core system of the human body for transporting oxygen and nutrients. The heart is the driving force of blood flow, and blood vessels constitute a well-connected transportation network. This network consists of arteries, veins and capillaries, which jointly undertake the important task of transporting fresh blood to the whole body and taking metabolic waste back.

The health of the cardiovascular system is closely related to the overall health of the human body. Whether there is a problem with the heart itself or a lesion in the blood vessels, it will directly or indirectly affect the function of various systems in the body.

First of all, the importance of heart health. As we all know, once the heart stops beating, life ends. The heart is like a water pump that never turns off, or an engine that powers the entire vehicle. For example, a steel engine made by Toyota has a lifespan of only about 30 years, while the human body, a "heart engine" made of flesh and blood, can beat continuously for 60, 80, or even 100 years. One cannot help but marvel at the ingenuity of creation and the wonder of life.

However, the key to maintaining the long-term operation of the heart lies in protecting the vascular system. If the blood vessels are hardened or blocked, it will seriously affect the heart's ability to supply blood to various parts of the body. If organs such as the liver, kidneys and brain are not supplied with enough blood for a long time, not only will their functions be weakened, but their structures may also be damaged.

What's more complicated is that these organs transmit ischemic signals back to the central nervous system through the nervous system, prompting the brain to issue instructions requiring the heart to increase its blood pumping capacity to meet the tissue's needs for oxygen and nutrition. The heart is therefore forced to increase its load, the pressure on the blood vessel wall increases, and blood pressure rises. If high blood pressure persists for a long time, it will not only accelerate the aging of the cardiovascular system, but will also damage important organs such as the liver, kidneys, and heart, forming a vicious cycle.

Therefore, the fundamental way to protect the cardiovascular system is to protect the patency and elasticity of blood vessels. Only when the blood vessels are healthy can the heart function efficiently and smoothly; only when the heart is strong can the flow of life continue to nourish every corner of the body.
