Having explored the Heart organ system and its integral role in health and disease, we now discuss the Small Intestine—the organ system charged with carrying out the mission of the Heart. The Small Intestine function is involved in making choices—what to eat, what to absorb of what we ate, what thoughts to entertain, what situations to engage in. When the Small Intestine function is healthy, we make choices that are true to our deeper nature, and therefore lead to real happiness and fulfillment.
