Answer with Explanation:
The four main tissue types are assembled according to their specific tasks. The<u> level of organization</u> will <u>depend upon a particular function that the tissue needs to carry out</u>.
For instance, the lining of the stomach consists of the following tissues from the inner to the outer:
- Mucosa (innermost)
- Submucosa
- Muscularis
- Serosa (outermost)
The "mucosa" is the<em> innermost tissue</em>. It is located in the "innermost" because it functions during<em> absorption and secretion.</em> 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<em> outermost tissue</em> because it <em>functions to reduce friction that is caused by the muscle movements.</em> 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.
