Making the world better, one answer at a time. The function of the projections of the mucosa of the GI tract is secretions and absorption.Digestion is also aided by these projections.he function of the mucosa is to warm and humidify air entering through the nose as well as to help to filter out unwanted particles in the air. 7 people found this useful.

The muscularis externa (muscularis for short) is the muscular wall of the GI tract, deep to (surrounding) the submucosa. The tongue and the muscularis of the upper esophagus consists of striated muscle. Along the rest of the tract, the muscularis consists of two distinct layers of smooth muscle.roceeding from the inside (i.e., ab luminally from the lumen): 1  Mucosa -- innermost layer (closest to the lumen), the soft, squishy lining of the tract, consisting of epithelium, lamina propria, and muscularis mucosae. 2  Submucosa -- connective tissue supporting (outside, deep to) the mucosa. The muscularis mucosae is a thin layer of smooth muscle at the boundary between mucosa and submucosa. It occurs throughout the GI tract from esophagus to rectum. It is thickest in esophagus, where it consists of relatively conspicuous bundles of longitudinal muscle fibers.roceeding from the inside (i.e., ab luminally from the lumen): 1  Mucosa -- innermost layer (closest to the lumen), the soft, squishy lining of the tract, consisting of epithelium, lamina propria, and muscularis mucosae. 2  Submucosa -- connective tissue supporting (outside, deep to) the mucosa. 1 The mucosa surrounds the lumen of the GI tract and consists of an epithelial cell layer supported by a thin layer of connective tissue known as the lamina propria. 2  The muscularis mucosa is a thin layer of smooth muscle that supports the mucosa and provides it with the ability to move and fold.he secretions of the associated glandular organs, such as the salivary glands, pancreas, liver, and gall bladder, aid the GI tract in accomplishing these functions. This laboratory will focus on the sequential segments of the gastrointestinal tract; the subsequent laboratory will focus on the glandular organs. 1 The mucosa surrounds the lumen of the GI tract and consists of an epithelial cell layer supported by a thin layer of connective tissue known as the lamina propria. 2  The muscularis mucosa is a thin layer of smooth muscle that supports the mucosa and provides it with the ability to move and fold.he secretions of the associated glandular organs, such as the salivary glands, pancreas, liver, and gall bladder, aid the GI tract in accomplishing these functions.

In Physiology, you will study the movement of food through the GI tract in detail. For now, it is important to understand a few basic principles and to relate them to the histological structure of the digestive system.he secretions of the associated glandular organs, such as the salivary glands, pancreas, liver, and gall bladder, aid the GI tract in accomplishing these functions. This laboratory will focus on the sequential segments of the gastrointestinal tract; the subsequent laboratory will focus on the glandular organs. A gastric pit is a shallow indentation in the surface epithelium of the stomach mucosa. These pits, which are lined by a protective epithelium of surface mucous cells, confer a characteristic texture to the entire surface of the stomach.roceeding from the inside (i.e., ab luminally from the lumen): 1  Mucosa -- innermost layer (closest to the lumen), the soft, squishy lining of the tract, consisting of epithelium, lamina propria, and muscularis mucosae. 2  Submucosa -- connective tissue supporting (outside, deep to) the mucosa. The surface for absorption is increased in many ways: the mucosa of the small intestine is thrown into folds called rugae; the mucosa itself has numerous finger-like projections called villi, and the epithelial cells are also covered with numerous projections called microvilli.ll the blood from the GI system below the esophagus drains into the hepatic portal vein. The portal system also drains the spleen and pancreas. Blood is conveyed to the liver for processing where it passes through millions of liver sinusoids. 1 Alimentary canal-mouth, pharynx, esophagus, stomach, small intestine, and large intestine. 2  Accessory digestive organs-teeth, tongue, gallbladder, salivary glands, liver, and pancreas. 3  Digestive Process-GI tract is a &#34disassembly&#34 line. 4  Nutrients become more available to the body in each step.verview. 1  The alimentary canal or gastrointestinal (GI) tract digests and absorbs food. 2  Alimentary canal-mouth, pharynx, esophagus, stomach, small intestine, and large intestine. 3  Accessory digestive organs-teeth, tongue, gallbladder, salivary glands, liver, and pancreas.
