 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 excretions. Only the digestive action started by saliva in the buccal cavity continues during conduction through the asophagus. Peristalsis is the process through which food moves from asophagus to stomach. Peristalsis involves the waves of contraction and relaxation in the smooth muscles of walls of elementary canal. This process starts with buccal cavity or pharynx and continues till the end of rectum. Dear students, a part of foregut is a 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 has to quickly feed it, it quickly stores its 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 birds are seen on the ground, they fly from the top and quickly feed it and then fly again. During this time, they store the food in the crop. Leaches which are infrequent feeders which are sometimes fed after weeks or months and they do not digest the food. They store the food in undigested form so they also have a big 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. It is treated with bacterial actions. Some animals which are usually birds and pigeons are a classic example of this. They prepare food for the nestlings in their crop which is called pigeon's milk.
