Answer 1

Answer:

if

1. The tongue is a muscular organ in the mouth of most vertebrates that manipulates food for mastication and is used in the act of swallowing. It has importance in the digestive system and is the primary organ of taste in the gustatory systems
2. The small intestine (small bowel) is about 20 feet long and about an inch in diameter. Its job is to absorb most of the nutrients from what we eat and drink. Velvety tissue lines the small intestine, which is divided into the duodenum, jejunum, and ileum.
3. The large intestine, also known as the large bowel, is the last part of the gastrointestinal tract and of the digestive system in vertebrates. Water is absorbed here and the remaining waste material is stored as feces before being removed by defecation.
4. The oesophagus is a muscular tube. It connects your mouth to your stomach. When you swallow food, the walls of the oesophagus squeeze together (contract). This moves the food down the oesophagus to the stomach. The upper part of the oesophagus is behind the windpipe (trachea).
5. The root of each tooth descends below the gum line, into the jaw.
6. the internal organ in which the major part of the digestion of food occurs, being (in humans and many mammals) a pear-shaped enlargement of the alimentary canal linking the oesophagus to the small intestine.
