Types of Tissue
an evaluation of the form-to-function relationship
Epithelial Tissue (Ciliated Pseudostratified Columnar Cells)
In the picture below it isn't exactly easy to see how the form-to-function relationship exists in this tissue. But it is present! These tissues are found in the trachea and other pulmonary passages (as well as the fallopian tubes of females). The cilia allow for movement of the mucus (which is secreted by the scattered goblet cells) away from the lungs so as to prevent any of the particles or bacteria that got caught in it from reaching the lungs. This is important in preventing bacterial infection as well as particles getting caught in the lungs.
