Describe The Four Tissue Types

Task 2 -describe the four different tissue types.
Epithelial tissue is a sheet of cells that covers a body surface or lines a body cavity. For example, epithelial tissue can be found in the stomach. There are two different types of epithelial tissue; simple and stratified. The simple epithelial has a single cell layer, whilst the stratified epithelial consist of two or more cell layers stacked on top of one another. They are tightly packed tissues and the two types can be seen in the image below. Epithelial tissues have two types of classifications simple and stratified; these again are based on the number of layers present. (Anatomy & Physiology, 2015) All epithelial tissue has six sides and varies in height for this reason there are different
The connective tissue acts as an entity and carries out most of the body functions. There are five different types of connective tissue on of the type being areolar tissue, the function of the areolar tissue is that it binds skin to the muscles beneath and is has a loose connective tissue that consists of a meshwork of collagen, elastic tissue, and reticular fibres. Another type of connective tissue is the adipose tissue which main function is it acts as an insulating layer to help reduce the heat loss from the body and forms a thick layer throughout the body the structure is that it’s a loose fibrous connective tissue packed with many cells. Blood tissues main function is to transport nutrients, waste and oxygen. Blood is composed of erythrocytes. (Ivy Rose,
I will now compare and contrast these tissues to see what they have in common and what they don’t.
The osseous tissue can be found all around the human body, as it is involved in the protection of the muscle, organs and soft tissues. Looking at the muscle through a microscope it consists of a central canal through which blood vessels and nerves pass. This means that the structure is vital for its function as if they didn’t have the central canal the blood vessel to pass through the osseous tissue. (The McGraw-Hill Companies, 1999)
Osseous tissue offers strong structural support to the human body, which serves a similar function to nervous tissue; as neuroglia function is to support the neuron cells in the nervous system. However although the function of both tissues are to act as support, the neuroglia tissue has a completely different structure. Within the neuroglia cell there are Ependymal cells which are the ones that offer protection to the neuron cells. They do this by forming a lining between the ‘ventricles of the brain and central canal of the spinal cord’. (Ivy Rose, 2015) This is also similar to the stratified squamous epithelial tissue which also has a function of supporting the outer layer of the skin and protects against abrasion, drying out and
