Study Notes
- The gastrointestinal system provides the body with water, electrolytes, and nutrients.
- The system consists of the fibromuscular tract and accessory organs and structures.
- Each part of the GI tract is adapted to its specific functions.
- The gastrointestinal wall has four layers: serosa, muscle layers, submucosa, and mucosa.
- The muscle layers are responsible for propulsive mechanisms and contain plexuses.
- The submucosa controls gastrointestinal secretion and local blood flow.
- The mucosa functions for absorption and secretion.
- The GI tract muscle fibers are in parallel bundles.
- The muscular layer is composed of smooth muscle cells.
- The GI system has sphincters to prevent aspiration and reflux.
