Classification of Tissues Introduction Cells are the smallest units of life. In complex organisms‚ cells group together with one another based on similar structure and function to form tissues .Tissues provide the numerous functions of organs necessary to maintain biological life. This lab exercise seeks to introduce the various tissues found in the human body and to familiarize you with their composition and function. The study of tissues is called histology ‚ and is important to the understanding

Cells of the body are organized into four fundamental tissues; epithelial‚ connective‚ muscle and nerve. Epithelial tissues line all surfaces of the body: the skin‚ cavities‚ ducts‚ vessels. They are named according to the cell shape on the free surface. Cells of a tissue are held together by the basement membrane and intercellular fibbers. These tissues receive their nutrition by diffusion‚ for they are without blood vessels. Simple squamous epithelium lines all blood and lymphatic vessel‚ including

Connective Tissue Characteristics of connective tissues • Extracellular matrix separates cells • Most widely variable of tissues • Many varied functions • Common (mesenchyme) origin • Degrees of vascularity Functions • Binding • Suport • Protection • Insulation • Transport Structural Elements • Fibers ⁃ Collagen (white) fibres ⁃ Elastin (yellow) fibers ⁃ Reticular fibers • Ground substance ⁃ Amorphous material fills space between cells and contains fibers

Epithelial Tissue covers body surfaces (epi‚ on + thelium‚ surface). Epithelial tissue consists of cells attached to one another to form an uninterrupted layer of cells that separates the underlying tissues from the outside world. The body’s epithelium not only covers its obvious surfaces (such as the epidermis of the skin and the linings of respiratory‚ urinary‚ and digestive tracts) but also extends into all of the complex invaginations which form lungs‚ kidneys‚ sweat glands‚ digestive glands

The lungs are made up of many types of tissue; the cartilages‚ ciliated epithelium‚ smooth muscle‚ squamous epithelium‚ elastic fibres and goblet cells and glandular tissue. The cartilage is a very stiff and flexible tissue‚ which doesn’t contain air vessels. It is found in trachea‚ bronchus‚ bronchiole and alveolus‚ and it has a structural role. It support‚ and gives strength to trachea and bronchi. It holds the airways open for the resistance with little airway. This prevents it from collapse

Epithelia form the surface of the skin‚ line the various cavities and tubes of the body‚ and cover the internal organs. Subsets of Epithelia Epithelia that form the interface between the internal and external environments. Skin as well as the lining of the mouth and nasal cavity. These are derived from ectoderm.

Question describe the different types of epithetical tissue including structure function‚ and location. Answer: there are many types of epithetical tissue with many different functions in different parts of the body that do many different things working together to do there job to maintain these conclusions‚ first off theres the simple squamous: known as a single layer commonly very flat known for filitration and & absorption found in the lungs and blood vessels‚ known as the circulatory system

Mohammad Ash-Shahid Biruar March 7‚ 2015 Case Study: Banana Time I. STATEMENT OF THE PROBLEM This case deals with the members of the “clicking” work group. The problem appears to be the lack supervision and management oversight as this group is completely isolated from other areas of the factory. This issue has led to different concerns including horseplay‚ extended breaks and operator disruptions which all lead to a loss in production. II. OBJECTIVES 1. To address the operator’s
