Answer with Explanation:
The four main tissue types are assembled according to their specific tasks. The level of organization will depend upon a particular function that the tissue needs to carry out.
For instance, the lining of the stomach consists of the following tissues from the inner to the outer:
The "mucosa" is the innermost tissue. It is located in the "innermost" because it functions during absorption and secretion. It is comprised of "goblet cells." These cells secrete mucus in order to provide protection to the mucous membranes. So, this is the reason why this tissue type is in the inner part.
On the contrary, the Serosa is the outermost tissue because it functions to reduce friction that is caused by the muscle movements. Since organs in the cavity move against each other, it is important to have a fluid (serous fluid) to prevent friction. So, this explains the reason why it is located on the outermost.
The four main tissues layers assembled together to make the stomach are: the mucosa, submucosa, muscularis, and serosa layers.
The body of an organism has levels of organization that build on each other. In this regard, cells make up tissues, tissues make up organs.
Microscopic analysis of the stomach's structure reveals that the (organ) stomach have a thin simple columnar epithelial layer for secretion and absorption. The submucosa is a thick layer of loose connective tissue that surrounds the mucosa. The layer also contains blood vessels, lymphatic vessels, and nerves
