Question

Rewrite the following in the correct sequence as directed within the brackets.
Water absorbed, Undigested food pass into large intestine. Formation of faeces, Absorption of digested nutrients by villi, Egestion (processes in small intestine and large intestine)

Answer 1

1. The intestine is a coil-like tube that is divided into two main parts- the small intestine and the large intestine.
   1. Small intestine:
      • The small intestine is the longest part of the digestive system and consists of three parts-duodenum, jejunum and ileum.
      • The inner surface of the small intestine is covered with numerous finger-like projections known as villi where absorption of digested nutrients takes place.
        
   2. Large intestine:
      • The large intestine is a coil-like tube that is connected to the small intestine at one end and to the anus at the other end.
      • It is a part of the alimentary canal which consists of three parts-cecum, the colon and the rectum. The undigested food from the small intestine passes into the large intestine.
      • The main function of the walls of the large intestine is to absorb water from the undigested food and to remove the faecal matter from the alimentary canal.
      • The process of elimination of undigested food materials from the body in the form of faeces is known as egestion.
