The five viscera, as one of the most important physiological organs in the human body, are crucial for maintaining normal physiological functions. The main functions of the five zang organs include the heart governing blood vessels, the lungs governing qi, the liver governing relaxation, the spleen governing circulation, and the kidney governing the storage of essence. Only when the functions of the five internal organs are normal can blood vessels be coordinated and unobstructed, and the human body can maintain a healthy state.

五脏，作为人体最重要的生理器官之一，对于维持人体正常生理功能至关重要。五脏的主要功能包括心主血脉、肺主气、肝主疏泄、脾主运化、肾主藏精等。只有当五脏功能正常时，血脉才能调和通畅，人体才能保持健康状态。
