a)A tissue is a group of cells that usually have a common embryonic organ and function together to carry out specialized activities.
a)Histology is the science that deals with the study of tissues.
3.List the four principal types of tissue.
a)The four principal types of tissue are Epithelial, Connective, Muscular and Nervous.
4.Describe the characteristics of Epithelial tissue.
a)The characteristics of Epithelial tissue are cells arranged in continuous sheets that cover a body surface or lines a body cavity, in either single or multiple layers.
5.List the two classifications of Epithelial Tissue types and give examples of each.
a)One is Epithelial tissue may be divided in two parts covering and lining forms the outer covering of the skin and some internal organs. It also forms the inner lining of blood vessels, ducts, and body cavities, and the interior of the respiratory, digestive, urinary, and reproductive systems.
b)Granular makes up the secreting portion of glands such as the thyroid gland, adrenal glands, and sweat glands.
6.Describe the functions of Simple Epithelium.
a) Simple epithelium is a single layer of cells that functions in diffusion, osmosis, filtration, secretion, or absorption.
7.Describe the characteristics and location of Simple Squamous Epithelium.
a)Simple Squamous Epithelium tissue consists of a single layer of flat cells that resemble a tile floor when viewed from the apical surface. The nucleus of each cell is a flattened oval or sphere and is centrally located, Simple squamous epithelium is present at sites where the processes of filtration (such as blood filtration in the kidneys) or diffusion (such as diffusion of oxygen into blood vessels of the lungs)occur. It is not found in body areas that are subject to mechanical stress (wear and tear).
8.Describe the function of Stratified Epithelium.
a)Stratified epithelium has two or more layers of cells. It is more durable and...
