  • The colon has three longitudinal bands made up of longitudinal muscles. These are called taeniae coli. 
  • Tonic contractions of teniae coli bunch up the colon into a succession of pouches called haustra (singular = haustrum), which are responsible for the wrinkled appearance of the colon. These pouches help the colon store and process waste material. They also assist in the absorption of water and the breakdown of nutrients.
  • Hence, the correct option is 2.
