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.
Each intestinal villus has a surface of simple columnar epithelium (absorptive cells and goblet cells) and a core of lamina propria. In addition the loose, cellular connective tissue that is typical of lamina propria throughout the gut, villi also contain capillaries, lacteals and smooth muscle fibers.ach intestinal villus has a surface of simple columnar epithelium (absorptive cells and goblet cells) and a core of lamina propria.
