A Human Is A Complex Organism

Human beings be complex and exceptional organisms as there is a complex arranging of cells in the human body. The organisation in the human body is summarised as follows Cells Tissues organs Systems Organism.The same type of cells which strain protrude a specific function ar organize into a tissue. For example, a group of nerve cells form a nerve tissue. They be organised to report in concert to perform specific functions as the result of cells in the human body do not work individually.An organ is a group of tissue that cooperates to carry step to the fore a specific life process. For examples, epithelial tissues form blood vessels. Several organs are organised into a system.Each system consist of several(prenominal) organs which are organised to carry out life processes such as respiration, reproduction and digestion.Various systems in the human body are well organised to carry out all the life processes efficiently. They are able to function because the cellular compone nts work together to ensure the survival of human beings.The human creative thinker is well developed to integrate informations and store them as memory. This acknowledges human beings to have the aptitude to talk, think rationally, prepare new things, learn from experience and use languages. The ability to do all these makes us really special compared to other organism.Water is driven into the tanks to raise density and allow the shooter to come down and it also pumped out to reduce density and hence allow the submarine sandwich to float. The tanks can be filled with water and air, which allows the submarine to sink or rise in the water. When a submarine is floating, its ballast tanks are filled with air, which makes it little dense than the sea water it displaces hence allowing it to float. Submarines sink when water is let into the ballast tank. This is because the submarines density becomes greater than that of the surrounding water, resulting in negative buoyancy and c ausation it to sink.
