Main tissues in the human body.

Extracts from this document...


´╗┐Hodon Abdi HSC Year 12 UNIT 5 P2 Ms Pasterkamp I am going to produce a written assignment which is meant to show an understanding of the main tissue types and the role they play in two named organs. Main tissues of the body There are varies different organs in the human body like for example the heart, lungs, kidneys and skin, which is actually the largest organ in the human body. Each organ in the body at least contains two different types of tissue that function together for a common purpose. Tissues are formed by a group of cells that carry out a similar function. These are the 4 main tissues in the body 1. Epithelium tissue 2. Connective tissue 3. Muscle tissue 4. Nerve tissue Epithelium tissue- is usual found in the outer layer of the skin and the inside of the mouth. Epithelium tissues? are mostly known for these function to protect and keep different organs in the body separate from each other and also keep the organs in place. Connective tissue includes many different types of tissues, which are found in the body, for example fat tissue, ligaments and blood is also considered as a connective tissue. Connective tissue helps to give support and strength to the body, as most types of connective tissue include fibrous strands of protein collagen which adds strength and support. ...read more.


Messages are sent through electrical signals to the body and every cell. Something typical of nerve tissues is that they send and receive information. Nerve impulses have a domino effect. When a neuron receives an impulse it passes automatically passes it to the next neuron, which does the same hence the domino effect. The neurons pass the impulses to the right path after a chain of chemical events Message or signals are picked up by the axon nerve, the axon nerve works by connecting to other nerve tissues and passing information through the end of the axon (dendrite) which picks up the electrical signal from the other neurons. Image The next paragraph I will be writing about three tissues or more that s found in the stomach and the function or roles the play within the digestive system and the stomach itself. I will also be writing about the location of the stomach in the body and function of the stomach in the digestive system. The functions of the digestive system are to break down our daily food molecules to a size where they could be delivered to cells and turn them into waste. The location of the stomach is usual described as the abdominal organ lying just beneath the diaphragm on the left side. ...read more.


The muscle tissue in the heart is involuntary because it?s not controlled by the brain and therefore carries out normal functions without instructions within internal organs e.g. beating of the heart. Nerve Tissue ? the nerve tissue has two systems, sympathetic and parasympathetic nervous system. The purpose of the sympathetic nervous system is to detect, if you?re under stress for example the sympathetic nervous system tells your heart to pump faster and supply more blood to your brain, when you feel nervous. The parasympathetic however is the nervous system that?s in use when a person is feeling normal; the parasympathetic system instructs the heart to beat at a normal pace. Nerve tissues contain voluntary muscle tissue, the voluntary muscles contract when it receives a nerve impulse from the central nervous system. Blood Tissue -Blood tissues are found usual in the heart or blood vessels, veins, arteries, arterioles, capillaries and venules. Blood tissue consists of 99% red blood cells, and 1% white blood cells. Blood tissue has varies functions, e.g. it controls the PH balance, removes toxin wastes from the body; it also dissolves gases (oxygen and carbon dioxide). Blood helps the heart function by circulating all the nutrients and oxygen to other organs in order for them to function properly. Blood is consider as connective tissue because it helps connect body systems together as it brings different organs much needed nutrients and oxygen. ...read more.

    Unlike epithelial tissue, connective tissue is characterised by the large amounts of intercellular substance (also called ground substance or the matrix) that it contains. Connective tissue is relatively few cells which are widely separated from each other. These living cells are responsible for secreting the large amounts of intercellular ground substance (matrix).
