Epithelial Tissue

Muscular Tissue

Connective Tissue

Nervous Tissue


SQUAMOUS EPITHELIUMProvides lining to the inside of the mouth, heart and blood vessels, but also reduces organs that rub together from friction.(Beckett, B.S.1981)


The role of the Epithelial tissues is to line the bodies surfaces such as cavities and organs.Substance that are absporbed or secreted is done through epitherial tissues. It has six main functions; apsorption protection, excretion, secretion, filtration and sensory reception. (Peate, I and Nair, M. 2016)

The role of the connective tissue is to bind the tissues ans orans together, which overall created reinforcement, insulation, protection and support. The connecive tissue provides reinforcement to the epithelial tissues as the epithelial tissue lies upon the connective tissue. (Peate, I, and Nair, M. 2016)

The role of the muscular tissue is to provide the body with posture and to use when the body needs to make a movement. There is three classifications of musclar tissues, these are; 1 - Smooth - Involuntary2 - Cardiac3 - Skeletal - Voluntary(Peate, I. and Nair, M. 2016)

The role of the nervous system iscontributed by two types of nervos tissues, these are neurones and neuroglia. The nerones are what makes the nervous tissue overall function and the neuroglia is what provdes the neurones with protection, support and nourishment. (Peate, I. and Nair, M. 2016)

VOLUNTARY MUSCLE TISSUELocated onto the skeleton and provides the body with movement and power, to be able to carry out daily tasks such as walking and picking things up. They are named voluntary muscle tissues as they are able to be contracted when the person desires. (Beckett, B.S 1981)

STRATIFIED EPITHELIUMProvides area such as the mouth and gullet, which are more rpone to damage with protection by severl layers of stratified epithelium, to prevent from damage and infection. (Beckett, B.S. 1981)

CUBICAL EPITHELIUMIs more commonly found in organs such as, salivary glands and thyroid follicles, that are created for secretion and diffusion. (McDougal, W. 2017)

CARDIAC MUSCLE TISSUESThis muscle tissue can only be located within the heart, when the fibres contract together, this provides the body with power to pump blood around the body, which ultimately provides human life. (Beckett, B.S. 1981)

CILLIATED EPITHELIUMMoves fluids or particles over epithelial tissues in regions such as the nasal region and trachea. (Dictionary of Biology, 2004)

INVOLUNTARY MUCLE TISSUELocated in the gut walls, bladder, and blood vessels. These muscle tissues are contract involuntarily, as they are not able to be contracted at the individual’s desire. The function that involuntary muscle tissues have is to move the food along the gut in an organised form. They have the appearance of being singular with a long form with a point towards the end of the tissue fibre. (Beckett, B.S. 1981)

COLUMNAR EPITHELIUMThis provides lining to areas such as the large kidney ducts, bladder, stomach, and the respiratory and reproductive systems. (Beckett, B.S 1981)

TRANSITIONAL EPITHELIUMThis allows the urinary organs to stretch and expand. But the main function is to act as a barrier to keep the toxins such as urine within the bladder and to not allow molecules and other water substances intot he bladder(Dr.Chen, No date)

NEUROGLIAThis is better known as a support system for the neurones, as the are not classed as neurones, insteadthey are cassified as cells that are within the nervous system. The function of the neuroglia is to - o Form myelin, which then wraps around the axon , which is a nerve cell which impulses are conducted fromt he cell body to other cells. o Provide important nutrients to the neurones, such as oxygen.o Get rid of pathogenso To provide a general support system that the neurones can sit upon.(Cheprasov, A. 2017)

NEURONESThere are three types of neurons, that are all needed for the brain to work effectivly with the rest of the body and vice versa. Sensory neuroneThis is when impulses that are received via the eyes, nose, mouth, ears and touch, are transferred to the brain/spinal ord region.Motor neuroneThe impulse that has been received via the sensory neurone, then conduct an action for the body to carry out, in accordance to what the sensory neurones have sent.(Beckett, B.S. 1981)Interneuron This neurone is not classified as eiter motor or sensory neurone, this because this is classed as the middle man, which effectvely transmits the infomration from the sensory nerone, towards the motor neurone.(, No date)

AREOLAR CONNECTIVE TISSUELocated between organs where spaces can be found and is made up of fibroblasts whichmake the fibres of areolar, masts cells which is produced by the matrix, macrophages which get rid of bcteria and are able to mov to infected areas of the body and fat cells.(Beckett, B.S. 1981)

CARTLIDGEHyaline CsrtlidgeCovers the surface of bones with a smoother surface, which enable the movement of joints more easy.FibrocartlidgeIs the strongest of te three cartlidges and it provides support and stringency to the area is is within.Elastic CartlidgeProvides support to the area, but also provides a structure and formation to an area. (Ivy Rose Holistic Health, 2017)

BONESThese are made up of a solid matrix which contain calcium, phosphate, carbonate and fluroide salts. Witin the bones theer are extremely narrow blood vessels which run the entire length of the bones The narrow channels that are within the blood vessels within the bones carry food and oxygen fromthe main bloodstream to the bone cells. (Beckett, B.S. 1981)

FIBROUS CONNECTIVE TISSUESThis tissue is what makes up the ligaments and tendons, which are what enabes the body to connect the muscles to bones and what holds joints together. The tendons re usually very togh and can wthhold alot of wear and tear, whre as the ligaments are made up of elastic fibres.(Beckett, B.S. 1981)
