Describe the various methods used to study anatomy. Anatomy is the study of structure and what makes up all the pieces parts of the human body. The easiest way to study anatomy is observation, dissection is also needed to see structures found below the surface, and there are other means of studying anatomy such as such as auscultation (listening) and percussion (touching). 3. What is the definition of physiology? Describe how comparative physiology is used to study physiology. Physiology is the study of function and how various body parts work. Comparative physiology is the study of organisms closely related to humans in order to gain a better understanding of the human model. 4. Name and describe the various levels of the hierarchy of complexity of the human body. The levels of hierarchy of complexity are organism, organ system, organ, tissue, cells, organelles, molecules, and atoms. An organism is composed of organ systems. Organ systems are composed of organs. Organs are composed of tissues. Tissues are composed of cells. Cells are composed of organelles. Organelles are composed of molecules. Molecules are composed of atoms. 5. Name
