An enlargement, or series of enlargements, in the anterior part of the alimentary canal, in which food is digested; any cavity in which digestion takes place in an animal; a digestive cavity. See Digestion, and Gastric juice, under Gastric.
Bag-like, expandable digestive organ between the esophagus (throat) and the small intestine; in birds, the stomach has two parts: the proventriculus (upper storage area) and gizzard (lower grinding area).
An organ that is part of the digestive system. It helps in the digestion of food by mixing it with digestive juices and churning it into a thin liquid. When food is swallowed, it passes first to the stomach, where the gastric juices start to digest it. After about one hour, the partly digested food moves on to the small intestine.
1 : Organ which digests food, a dilatation of the alimentary canal which connects on the top with the esophagus and on the bottom with the duodenum via a valve called the Pylorus and being typically a simple often curved sac with an outer serous coat, a strong complex muscular wall that contracts rhythmically, and a mucous lining membrane that contains gastric glands 2 : the part of the body that contains the stomach : BELLY, ABDOMEN
Located in the upper part of the abdomen and in front the pancreas, the stomach is a saclike organ that connects from the esophagus to the small intestine. The stomach stores and assists in the breakdown of food.
Located in the upper central portion of the abdomen, between the esophagus and small intestine the stomach produces gastric juices (acid) which break down proteins to begin the process of digestion. (Cancer)
The part of the vertebrate gut system that follows the esophagus. It is expanded to form a chamber, and its walls secrete pepsinogen, giving rise to pepsin, rennin, and hydrochloric acid. Gastric secretions also include mucin, which lubricates the food mass that is passed a little at a time to the small intestine via the pyloric sphincter.
a sack-like, muscular organ that is attached to the esophagus. Both chemical and mechanical digestion takes place in the stomach. When food enters the stomach, it is churned in a bath of acids and enzymes.
The sac-shaped digestive organ that is located in the upper abdomen, under the ribs. The upper part of the stomach connects to the esophagus, and the lower part leads into the small intestine. See the entire definition of Stomach
The stomach is an organ used to digest food. It has a saclike shape and is located between the esophagus and the intestines. It changes size and shape according to its position in the body and the amount of food inside. Food enters the stomach from the esophagus. Once food enters the stomach, gastric juices are used to break down the food. The other end of the stomach empties into the small intestine. Small Intestine The small intestine is the upper part of the intestine, where the most extensive part of digestion occurs. Most food products are absorbed in the small intestine. The lining of the small intestine secretes a hormone called secretin, which stimulates the pancreas to produce digestive enzymes.
A hollow, muscular, J-shaped pouch located in the upper part of the abdomen to the left of the midline. The upper end (fundus) is large and dome-shaped; the area just below the fundus is called the body of the stomach. The fundus and the body are often referred to as the cardiac portion of the stomach. The lower (pyloric) portion curves downward and to the right and includes the antrum and the pylorus. The function of the stomach is to begin digestion by physically breaking down food received from the esophagus. The tissues of the stomach wall are composed of three types of muscle fibers: circular, longitudinal and oblique. These fibers create structural elasticity and contractibility, both of which are needed for digestion. The stomach mucosa contains cells which secrete hydrochloric acid and this in turn activates the other gastric enzymes pepsin and rennin. To protect itself from being destroyed by its own enzymes, the stomach's mucous lining must constantly regenerate itself.

Stomach cancer is rare in dogs and cats. Signs vary but may include vomiting (especially if blood is present), weight loss, anemia and lack of appetite. Bowel movements may be dark and tarry in nature. Most stomach tumors are malignant with evidence of spread to lymph nodes or liver, making treatment difficult. Treatment is generally with surgery, especially for benign tumors, although they are rare.
