Introduction to Anatomy and Physiology 1. Major Themes of Anatomy and Physiology A. Functional Hierarchy B. Structure Function Structure C.Homeostasis 2. Levels of Structural Organization A. Subatomic Particles -form atoms B. Atoms -form molecules C. Molecules -form organelles -form follows function (shape of a molecule determines its function) D. Organelles -form cells -Cell Theory 1. Cells are building blocks of all plants and animals 2. all cells come from the division of preexisting cells 3. cells are the smallest unit that perform all vital physiological functions 4. each cell maintains homeostasis at the cellular level 5. homeostasis at the level of the tissue, organ, organ system, an organism reflects the combined and coordinated actions of many cells E. Cells -form tissues -cells are the smallest living units in body; organelles are their structural and functional components F. Tissues -form organs -a tissue is a group of cells working together to perform one or more specific actions G. Organs -form organ systems -organs consist of 2 or more tissues working in combo to perform several functions H. Organ System -form organisms - organs interact in organ systems(cardiovascular, digestive) What is Anatomy? Anatomy is the study of structure and the relationship between structures. 1. Important Anatomical Principles A. Form  Function B. Functional Units

-organs consist of functional units -functional unites usually serve as exchange surfaces C. Surface Volume Rule -small units = more surface area, thus forcing functional units to become smaller D. Distributive Trees -branching networks deliver material to functional units 2. Subdivisions of Anatomy Include A. Surface Anatomy B. Gross Anatomy - involves the examination of relatively large structures and features usually visible with the unaided eye C. Systemic (Systematic) Anatomy D. Regional Anatomy E. Radiographic Anatomy F. Developmental Anatomy G. Embryology H. Histology -examination of tissues (groups of specialized cells and cell products that work together to perform specific functions) -tissues form to build organs I. Cytology -analysis of the structure of individual cells (the simplest unit of life) J. Pathological Anatomy What is Physiology? Physiology is the study of how body structures function. 1. Subdivisions of Physiology A. Cell Physiology - study of function of cells B. Pathophysiology - study of effects of diseases on organ or system functions C. Exercise Physiology D. Neurophysiology E. Endocrinology F. Cardiovascular Physiology G. Immunology H. Respiratory Physiology I. Renal Physiology An Introduction to the Human Body All body systems influence one another, work together to maintain health, provide protection from disease, and allow for reproduction of the species 1. Eleven Systems of the Human Body 2. We will discuss: A. The Autonomic Nervous System B. The Endocrine System
