What are the 8 levels of organization of the human body? An, smallest independently functioning unit ofallorganisms; in animals, a cell contains cytoplasm, composed of fluid and organelles, functionally distinct structure composed of two or more types of tissues, group of organs that work together to carry out a particular function, living being that has a cellular structure and that can independently perform all physiologic functions necessary for life, group of similar or closely related cells that act together to perform a specific function. The smallest unit of any of these pure substances (elements) is an atom. These include the chemical, cellular, tissue, organ, organ system, and the organism level. Human body: The physical component of the human organism, the human body is made up of extracellular and live cells and is divided into many tissues, organs, and systems. Out of these, the cookies that are categorized as necessary are stored on your browser as they are essential for the working of basic functionalities of the website. Molecules are the chemical building blocks of all body structures. The life processes of the organism are built and maintained at several physical levels, which biologists call levels of organization: the cellular level, the tissue level, the organ level, the organ system level, and the organism level (shown). Typical levels of organization that one finds in the literature include the atomic, molecular, cellular, tissue, organ, organismal, group, population, community, ecosystem, landscape, and biosphere levels. Assigning organs to organ systems can be imprecise since organs that belong to one system can also have functions integral to another system. Figure1.5Organ Systems of the Human Body (continued)Organs that work together are grouped into organ systems, The organism level is the highest level of organization. For example, a tumor can interrupt the function of the organ it is in, despite the fact that it is a molecular mutation with direct cellular implications. Living things adapt to their environment. The kidneys, ureters, and urinary bladder altogether form the urinary system.ii. Born and raised in the city of London, Alexander Johnson studied biology and chemistry in college and went on to earn a PhD in biochemistry. Figure 5.1.
