Weekly Assignment: Tissues

Description

Instructions
Below here, there are six tissue descriptions. Write a few sentences for each description answering the following questions:

Is it an epithelial or connective tissue? Why?
Which subtype of epithelial or connective tissue? Why?
Example
Description Sample: Lines the gastrointestinal tract forming a hollow tube. In this region, absorption is essential.

Answer: This is an epithelial tissue because it “lines” a series of organs (the GI tract) and it faces a hollow region (lumen), which means it has an apical surface. As for the classification, I believe this is a simple columnar epithelium: simple because a single layer of cells is required for absorption and columnar because the gastrointestinal tract presents columnar cells.

Tissue Descriptions
Description #1:

Lines the inner walls of the ureter, which are continuous with the bladder. This tissue type allows them to stretch as urine passes from the kidneys to bladder, and then return to their original shape.

Description #2:

This tissue is a mucous producing and protective, clearing particles from inhaled air prior to it reaching the lungs. It is mainly found within the trachea or windpipe.

Description #3:

Contains collagen fibers tightly packed and parallel to each other with fibroblasts scattered all over. Makes ligaments and tendons.

Description #4:

One layer of cells that lines the inner walls of the capillaries, our smallest blood vessels. Across this tissue is where oxygen, carbon dioxide, and nutrients are exchange between the blood and body.

Description #5:

Lines the outside of our body. It has multiple layers of cells and a tough layer on top to provide protection from injuries and sun exposure of the underlying layers.

Description #6:

It contains elastic fibers on top of collagen fibers. It has the ability to stretch and return to its original shape. It is found in the walls of the arteries.
