Essay on Epithelial Tissue

All cells group together within the body to form tissue, a collection of similar cells group together to perform a specialized function. There are four primary tissue types in the human

This series of courses covers the structure of the body’s parts – their forms and how they are organized – and their function, anatomical and disease state terminology.

4. Organ level- Organs are made up of different types of tissues. Organ is a discrete structure composed of at least two tissue types that performs a specific function for the body.

Organ system is a group of organs that work together to perform a certain task.  Humans

Tissues: Tissues are groups of similar cells that have specific functions. In this piece of work I’ll talk about these types of cells:

3. Describe the primary functions of each type of body tissue and give examples of each.

Tissues are groups of cells, which are placed together to achieve a common function. There are four main types of tissue: Epithelial, connective, muscle and nervous. Most of these tissues are found in our bodies, however the epithelial tissue is covered all over the surfaces of the body.

1-1: List the four types of tissue found in the human body and give an example of each.

1. List the 4 primary tissue types and give the general characteristics and functions of each one.

Epithelial-mesenchymal transition (EMT) is a cellular process that is essential for normal processes in many organisms, including embryonic development and wound healing, and is recapitulated in human disease, contributing to organ fibrosis and cancer progression (Thiery et al. 2009; Yang and Weinberg 2008). EMT describes the conversion of a cell with an epithelial phenotype to one with mesenchymal characteristics and can be a partial or complete transformation. Epithelial cells form the borders of tissues and organs, and are characterized by apical-basal polarity, contact with a basement membrane, and strong adherence to other epithelial cells through intercellular junctions including adherens junctions, tight junctions, and desmosomes. Conversely, mesenchymal cells have front-rear polarity and generally lack cell-cell contact, allowing them to be motile. During human embryonic development, EMT is essential for the formation of a variety of tissues, including mesoderm, neural crest, somites, palate, pancreas, liver, reproductive tracts, and heart valves (Thiery et al. 2009; Yang and Weinberg 2008). After development, partial EMT also contributes to wound healing (Thiery et al. 2009). However, EMT can also play a more insidious role by factoring into tumour progression.

In this assignment I’m going to talk about the structure of the main tissues which are found within the body as well as what their role is in the terms of two named organs of the body. Tissues are a collection of similar cells that group together to carry out a specific function within the body. There are four different types of tissue found in the human body which include; epithelial tissue; connective tissue; muscle tissue and nerve tissue.

When cells are grouped together they form what is known as a tissue. Different types of tissue make up different types of organs. The 3 main types of tissue are Muscular, Nerve and Epithelial. The muscular tissue is made up of three forms, they include the skeletal, smooth and cardiac tissues.

Our body has levels that build up on each other, we have cells that make up tissues, and tissues that makeup organs, and organs that can make up organ system. Each cell type for the function has its own way of functioning in the body, but they all work together to release the necessary fluids the body needs and perform their function.

Cells are some of the smallest organisms around. All living things consist of cells, and yet they are invisible to the naked eye. Cells are the basic structural and functional units of life. Cells are made up of many different parts which allow them to function properly.
