Various systems of the human body obtain an array of nutrients, water and oxygen content from the blood. These substances are used to perform oxidation to generate heat energy to ensure proper function of the system; at the same time, waste produced by metabolism such as carbon dioxide, urea, uric acid and other waste products are discarded into the blood for further processing. These waste products are then transported to the respiratory system and excretory system to be excreted from the body, maintaining the function and chemical properties of the internal body system. This shows the importance of the circulatory system.
As humans age, impurities such as cholesterol, fat, calcium, and more will be deposited on the inner wall of blood vessels. This phenomenon results in thickened blood, increased blood lipids, narrower blood vessels, and hardening of blood vessel walls. Impurities in blood vessels often presents itself in symptoms such as poor blood flow, insufficient oxygen supply, dizziness, lethargy, high blood pressure, Usually manifested as poor blood flow, insufficient oxygen supply, causing dizziness, general weakness, high blood pressure, partial illness in the body, and etcetera. Severe cases of clogged blood vessels may lead to coronary heart disease, cerebral thrombosis and varying cardiovascular and cerebrovascular diseases.
