Write different parts of alimentary canal are :

• Bucal  Cavity - Mouth, also called oral cavity or buccal cavity, in human anatomy, orifice through which food and air enter the body. The mouth opens to the outside at the lips and empties into the throat at the rear; its boundaries are defined by the lips, cheeks, hard and soft palates, and glottis.
• Foodpipe or oesophagus - The food pipe (oesophagus) is part of your digestive system. It is the tube that carries food from your mouth to your stomach. It lies behind the windpipe (trachea) and in front of the spine.
• Stomach - the organ in your body where food goes after you have eaten it
• Small intestine - the part of the intestine that runs between the stomach and the large intestine; the duodenum, jejunum, and ileum collectively.
• Large intestine - The long, tube-like organ that is connected to the small intestine at one end and the anus at the other. The large intestine has four parts: cecum, colon, rectum, and anal canal. Partly digested food moves through the cecum into the colon, where water and some nutrients and electrolytes are removed.
• Rectum and Anus - The rectum is a chamber that begins at the end of the large intestine, immediately following the sigmoid colon, and ends at the anus (see also Overview of the Anus and Rectum).
