Stomach is a muscular J shaped thick walled bag. It receives food from the oesophagus and opens into the small intestine. It is the widest part of the alimentary canal. It churns the food to mix the digestive juices. Mainly protein is digested in the stomach. It also secretes HCl that kills microbes and activates the enzymes.
