 Dear students, in this topic we shall discuss the foregut and study its various parts and discuss in detail the asophagus and crop. The foregut includes the food conducting region, asophagus, food storage region, stomach. It also includes crop in some animals, asophagus is the part in which food enters after swallowing. It is a tubular part which conducts food from pharynx to the stomach. It does not produce any digestive enzymes or any secretions. Only the digestive action started by saliva in the buccal cavity continues during conduction through the asophagus. Peristalsis is a process through which food moves from asophagus to stomach. This involves the waves of contraction and relaxation in the smooth muscles of walls of elementary canal. This process of peristalsis begins with buccal cavity or pharynx and continues till the end of rectum. Dear students, foregut is a part of crop which is found in some animals. This part is an exact like expanded section which is found in asophagus. It is used to store food without digesting. It is generally found in such animals which are either quick feeders or they are infrequent feeders. It allows the quantities of food to be stored for digestion at a later time. If an animal quickly feeds on the food, it quickly stores the food in the crop which it will digest later. Crop is found in many birds. For example, it is present in chicken. Birds are usually quick feeders. If the seeds are seen on the ground, then they come on the ground and quickly feed. After that, they fly again. At this time, they store the food in the crop. Leaches which are infrequent feeders and feed after weeks or months. They do not digest the food fully. They store the food in undigested form and have a very large crop. Dear students, crops store food without digestion. This is their major function. Apart from this, it is also used to store food in crops. That is, it is treated with bacterial actions. Some animals, which are usually birds, or pigeons, prepare food for the nestlings in their crop.
