In the cat, the esophagus lies behind the trachea (as it does in humans). The esophagus provides a passageway for food to the stomach, which lies below the diaphragm in the abdominal_cavity.

The liver and gall_bladder are below the diaphragm and conceal part of the stomach. If you reflect the liver you can find the pancreas lying in the mesentery that supports the intestines.

The small_intestine (duodenum, jejunum, and ileum) extends from the base of the stomach to the cecum of the colon.

The spleen (which is lymphatic, not digestive) is clearly visible on the left side of the abdomen.

Mesenteries are double-layered extensions of the peritoneum that provide support for the abdominal organs. Mesenteries provide routes for blood vessels, lymphatics and nerves to reach the digestive organs. They also hold organs in place and store fat. There are dorsal as well as ventral mesenteries. The greater and lesser omenta (sing: omentum) are examples of mesenteries.

The omenta extend from the upper curvature (lesser_curvature) of the stomach (lesser_omentum), and from the greater_curvature of the stomach down over the abdominal organs (greater_omentum).

The liver and gall_bladder are below the diaphragm and conceal part of the stomach. If you reflect the liver you can find the pancreas lying in the mesentery that supports the intestines.

The liver and gall bladder are accessory organs that are associated with the small intestine, specifically the duodenum. The liver is a site for many metabolic activities. Among them is the production of bile (a fat emulsifier) for export to the small intestine. The gallbladder houses bile until it is needed in the duodenum.

The liver is organized into four sections called lobes. The largest of these is the right lobe. Histologically, the interior of the liver is organized into hexagonal lobules. Each lobule consists of plates of hepatocytes that are organized around a central_vein. In between the "plates" of cells are large, leaky capillaries known as liver_sinusoids. Special macrophages, known as hepatic_macrophages (Kupffer_cells), "patrol" liver lobules and sinusoids.

Each of the six corners of a lobule has a region called a triad (portal_triad), which consists of a branch of the hepatic_artery, a branch of the hepatic_portal_vein, and a bile_duct.
