REFLECTION PAPER: ANIMAL TISSUE
While writing my notes about animal tissues, I’ve learned so many things about the
difference, structures and functions of the different divisions of this tissue. I have also
learned that this is not just any other part of our body, this is actually one of the most
important parts of our body that regulates different specific functions. Base on the
handout, animal tissue is a group of connected cells that have a similar function within
an organism. It is composed of 4 distinct types of animal tissue; These are the epithelial,
muscle, nervous, and connective tissue that are all also classified into various subtypes.
I have also learned that all animal tissues have a feature in common and it is the
extracellular matrix, a nonliving where cells are embedded. It is a mixture of water,
carbohydrates, lipids, and protein fibers such as collagen and elastin. Epithelial tissue
such as the outermost layer of the skin which is the epidermis, the lining of the mouth,
nose and digestive system is made up of layers that serve as protection for organs. It
always has a free surface that is exposed either to the outside or to a space within the
body and is also classified into various types according to the shape of their cells and
the basis of the number of cell layers; Squamous epithelium can be found ​inside of
blood vessels, Columnar Epithelium is cylindrical and is found in the lining of the
stomach and intestine, Glandular Epithelium is found in the sweat glands and tear
glands and produces a secretion. Ciliated epithelium found in the lining of the
respiratory tract that ha cilia at the topmost of it, Cuboidal epithelium found in the
lining of the kidney tubules, and lastly, the Stratified epithelium is found in the place
like epidermis of the skin, the lining of the mouth cavity and esophagus. Muscle tissue
is also classified into three types, these are smooth muscle, skeletal muscle and cardiac
muscle. One of its major functions is the movement of our body’s skeleton, Respiration,
communication, pumping blood and many more. The connective tissue that connects
different organs and other tissues is also classified Into three which are the blood, bone,
cartilage and connective tissue proper. The last one is the nervous tissue, which is
formed by neurons and neuroglia. Without these many levels of structural organization,
our body or an organism's body will not function as it is since they are well-specialized
to protect our different vital organs and to absorb elements that are necessitated for our
body to work properly from the external environment.
