The Main Body Tissues
Introduction
Tissue just means a group of cells that together carry out a particular job in your body.
There are four different types of tissue within the human body. This consists of the connective tissue, the epithelial tissue, the muscle tissue and the nervous tissue. Each of these tissues are vital for our bodies and each tissue has a very important role to fulfil.
Epithelial tissue
Epithelial tissue protects your body from moisture loss, bacteria, and internal injury. It is made up of cells closely packed and ranged in one or more layers. There are two kinds of epithelial tissues, these are the covering and lining epithelium which covers or lines almost all of your internal and external body for example, the outermost layer of your skin and other main organs, and the internal surface lining of digestive system. Then there is the glandular epithelium which secretes hormones or other products such as stomach acid, sweat, saliva, and milk. Epithelial tissue can be divided into two groups depending on the number of layers of which it is composes. Epithelial tissue which is only one cell thick is known as simple epithelium. If it is two or more cells thick such as the skin, it is known as stratified epithelium and squamous cells have the appearance of thin, flat plates.
Connective Tissue
Connective tissue generally provides structure and support to the body, there are also two types of connective tissue. Loose connective tissue holds structures this means the loose connective tissue holds the outer layer of skin to the underlying muscle tissue. This tissue is also found in your fat layers, lymph nodes, and red bone marrow. Bone marrow is the flexible tissue in the interior of bones and it is vitally important.
Fibrous connective tissue also holds body parts together, but its structure is a bit more rigid and dense than the loose connective tissue. Our fibrous connective tissues are found in ligaments,
