Produce a written assignment showing an understanding of the four main tissue types (epithelial, muscle, connective and nervous) and what they do in

the heart and the intestine.

Tissues are groups of cells with a common structure and function. There are four main tissues in the body - epithelium, muscle, connective tissue and

nervous tissue.

Epithelial tissue-

Epithelial tissue covers external surfaces and internal cavities and organs. Glands are also composed of epithelial tissue. It is made up of cells closely packed and ranged in one or more layers; compound epithelia is made up of several layers of cells and Simple epithelia is a single layer of cells. Simple epithelial includes four different types; squamous, cuboidal, ciliated and columnar. Epithelial tissue, regardless of the type, is usually separated from the underlying tissue by a thin sheet of connective tissue; basement membrane. The basement membrane provides structural support for the epithelium and also binds it to neighbouring structures. As a group, epithelial tissues perform a variety of functions, including protection, absorption, excretion, secretion
