Concept explainers
To discuss:
The mechanism of transitional epithelium and its special protective property.
Introduction:
Epithelial cells are a sheet of adhering cells that cover the body surfaces and cavities in the form of internal and external linings of body organs and tissues of glands. The main functions of the epithelial cells are protection, secretion, absorption, excretion, sensation, and filtration.
Stratified epithelial cells consist of 2 to 20 layers of epithelial lining, which appears in a simple, cuboidal, and columnar shape. It acts as a protective layer because it has more number of layers. It has capabilities to withstand epithelial abrasions. It undergoes self-renewing process, where the epithelial cells constantly fill the cavities of organs.

- Loose Connective Tissue Please refer to the pic that's attached to answer my question Compare the structures and functions of loose connective tissue to those of epithelial tissue. What percentage of loose connective tissue is composed of cells, as opposed to the matrix? What is the function of each type of cell observed? What percentage of the matrix are fibers and what is the function of each type of fiber?arrow_forwardSimple epithelial are concerned with absorption, secretion, and filtration 5. What is the extracellular matrix of connective tissue composed of? It is composed of cells that produce and secrete protein fibers and thearrow_forwardLoose adipose connective tissue has brown and white (yellow) forms. Where would I find each in the body, and how are they different regarding function? What would be one good way to tell the difference between loose and dense connective tissues on a slide under a microscope? What major cells would I find in dense elastic connective tissue? 3b. What are the major cells I would find in elastic cartilage? What are some characteristics of stratified squamous epithelium?
