Biology; Zoology; Biology; Marine Biology. 248 DAYA SHANKAR SARBAHI. pericardial cavit liver hepatic duct gall bladder pyloric constriction pancreatic duct pyloric portion of stomach duodenum pyloric caeca pancreas bile duct small intestine cardiac portion of stomach rectum anus urinogenital aperture body wall spleen abdominal cavity FIGURE 3. Ventral view of the largemouth black bass with body wall and adipose tissue removed to show the digestive tract. lines the wall is raised into longitudinally disposed folds presenting a somewhat zig- zag pattern (Fig. 2). Posteriorly, the intestinal bulh curves to the left with a slight constriction and passes into the intestine. The pyloric caeca are absent in this species. The remaining part of the elongated digestive tract behind the intestinal bulb is an elongated, comparatively thin-walled tube, more or less uniform in diameter and disposed into a number of intermixed coils, which fill the entire ventral portion of the abdominal cavity. Two regions of the intestine proper are distinguished by the disposition of folds of the mucous membrane. The folds present a zig-zag pattern, which in the an- terior intestine is composed of straight lines and angles, while in the posterior intestine it is produced by convoluted lines (Fig. 2). The rectum is a relatively short tube, and is distinguished from the intestine by the presence of obliquely transverse folds in the mucous membrane. These ana- stamose at intervals (Fig. 2)..
