In short, it is the human being (or organism) as a whole. Start studying 7 levels of organization of the human body. Therefore, molecules combine to form cells, cells combine to form tissues, tissues combine to form organs, organs combine to form organ systems, and organ systems combine to form organisms. Wish in a little way i can help you undertand. Complex functions begin to emerge at this level. The organization of the body often is discussed in terms of six distinct levels of increasing complexity, from the smallest chemical building blocks to a unique human organism. The respiratory system, for example, uses the lungs, airways and respiratory muscles to inhale oxygen and release carbon dioxide in animals. Look at the video!! A human cell typically consists of flexible membranes that enclose cytoplasm, a water-based cellular fluid together with a variety of tiny functioning units called organelles. The human body is like a machine in all these ways. These include the chemical, cellular, tissue, organ, organ system, and the organism level.

Introduction to Anatomy Module 3: Structural Organization of the Human Body. The human body has 6 main levels of structural organization. Briefly describe the 6 (six) levels of structural organisation of the human body in order from the smallest structural unit to the largest (in 130-150 words). Higher levels of organization are built from lower levels. Individual cells may have some common functions but vary widely in size and shape. Humans are multi-cellular animals. List the 11 organ systems of the human body and explain their major functions. Each bacterium is a single cell. Organ level– an organ is a structure composed of at least two different tissue types that perform a specific function within the body. structural levels working together. Levels of Structural Organization of the Human Body. A large amount of the molecules that are important to living things are called macromolecules. Each organ performs one or more specific physiological functions. Organ Systems of the Human Body (continued).
