What are the main functions of the spleen?

The choice stating that the spleen governs transportation and transformation, and controls the blood, accurately reflects the traditional Chinese medicine (TCM) understanding of the spleen's functions. In TCM, the spleen is considered essential for digestion and the transformation of food into Qi (vital energy) and blood. It is responsible for extracting nutrients from food and distributing them throughout the body, thus playing a crucial role in nourishment and energy supply.

Additionally, the spleen is linked to the production and regulation of blood. A healthy spleen is believed to ensure that there is adequate blood circulation and that the body maintains a proper supply of Qi and blood, which are vital for overall health and vitality. If the spleen's function is compromised, it can lead to issues such as fatigue, weakness, and various digestive problems, as well as blood deficiencies.

Other options regarding the functions of the spleen are less accurate within the TCM framework. The first choice, related to respiration and opening into the nose, pertains more to the lungs. The third choice addresses Qi dominance and water regulation, which are functions attributed more to the kidneys. The fourth choice touches on muscle growth and facial features, which again may relate more to the overall health influenced by spleen
