P2 †Describe the Four Main Tissue Types in the Body

The Cell P2 Describe the four principal(prenominal) create from raw stuff types in the body Inside the body, there argon four authoriseds types of meander paper which include the Epithelial, Muscular, Nervous and Connective. tissue papers atomic number 18 know as groups of cells which have a certain structure to retain a specific job. Epithelial wind covers the body surface and forms the lining for most internal cavities. It protects our insides, its cognize as the skin. It also absorbs in the intestinal lining and stomach, another(prenominal)wise known as the gut. It also filters in the kidneys and secretes(forms glands).Epithelial cells are attached to each other closely forming a protective hindrance and have no demarcation vessels but can soak up nutrients from decline vessels in conjunctive tissue from underneath. It protects the body from dirt, dust, bacteria and other microbes which could harm you. It is innervated which means it has a lot of nerves in it and it is very good at renew for example having a grazed knee or sunburn. It also protects the main organ which is the heart, from rubbing against and harming the lobes in the heart against lungs.It gives us an extra barrier for security and saves the heart from many different injuries and also helps protect the speed body around the heart area. Connective Tissue is internal back for our organs, it protects them and wraps around them kindred a cushion. It stores nutrients and runs through the organs capsules and inside robust layers of the skin. These tissues have some sort of supporting role, which include bone, tendons, blood, adipose and cartilage.There are three different categories for connector tissue Supportive connective tissues are like bone and cartilage, Fluid connective tissues are like the blood and Connective Tissue proper are both loose and heavyset connective tissue, which links the tissues together. Bones support the lungs and protect from injury. Elastic connectiv e tissue is also embed in the lungs and is able to extend like an elastic band when forced. Connective tissues also give shape and effectuality to other tissues that form the heart, it ensures the heart beats and functions properly..Nervous Tissue is the main office of the noisome system, it conducts impulses too and from body organs by neutrons. The three main elements of nervous tissue are found in the brain, spinal cord and nerves. Nervous Tissue controls many systems in our bodies without us being mindful of it. When we breathe, air moves in to our respiratory system and if we should choke a spit out reflex should occur by nerve reflexes sent from the brain. Nervous tissue also plays a big part in our cardio vascular system, it machinelikely tells the heart to beat and keeps blood pumping around the body, this also controls the heart rate.Functions of the nervous system are sensory input, integration, control ofmusclesand glands,homeostasis, and mental activity. Muscular Tissue is responsible for the bodies movement, moves food, blood and waste through the bodies organs and is responsible for mechanical digestion. There are three different types of muscle tissue polish up Muscle found in blood vessel walls and organ walls and spindle-shaped cells for pushing things through organs, involuntary. Skeletal Muscle found in orotund body muscles, voluntary, packed in bundles and attached to bones for movement.Skeletal muscles are important for holding bones in the correct position so they are essential to the rib cage to protect your respiratory system reservation sure your cardio vascular system receives enough oxygen. cardiac Muscle found in the heart wall, involuntary and striated muscle with intercalated discs connecting cells for synchronized contractions during the hearts beat. Cardiac muscles ensure the heart receives oxygen from the lungs which is carried through the blood, when the cardiac muscles relax by and by contracting the heart fills w ith blood containing oxygen.
