The second guna is rajas, that is the stage when man starts the active process of self-development, transcends dumb primitiveness, grows as a warrior, and then as a leader, organizer of other people. The third guna is sattva, that is purity, harmony, bliss, happiness.
Villi also help the food to move along the digestive tract. Food takes three to six hours to move through the small intestine. The small intestine has three parts, the duodenum, jejunum and ileum.
The villi are the parts that absorb nutrients from food and pass them into the bloodstream. Villi are also covered with microvilli. The purpose of both structures is to increase the small intestineâs surface area so that nutrient absorption is enhanced.
