levels of structural organization in the human body
Explain how form and function are related in human cells. In fact, most organs contribute to more than one system. In multicellular organisms, including humans, all cells, tissues, organs, and organ systems of the body work together to maintain the life and health of the organism. In addition to those listed above, we also have the respiratory, cardiovascular, nervous, endocrine, lymphatic, Anorganis an anatomically distinct structure of the body composed of two or more tissue types. The organism level is the highest level of organization. All matter in the universe is composed of one or more unique pure substances called elements, familiar examples of which are hydrogen, oxygen, carbon, nitrogen, calcium, and iron. A number of organ systems, including the cardiovascular and respiratory systems, all work together to do this. WebOur human body consists of 6 levels of structural organization. Legal. Figure \(\PageIndex{2}\):Organ Systems of the Human Body Organs that work together are grouped into organ systems. All living structures of human anatomy contain cells, and almost all functions of human physiology are performed in cells or are initiated by cells. PDF. The female ovaries and the male testes are a part of which body system? { "13.01:_Muscle_Contraction" : "property get [Map
