Brittany Sauer BIO 201- G12 Chapter One Study Questions- The Human Body: An Orientation 1. Anatomy- studies the structure of body parts and their relationships to one another, concrete, can be seen, felt and examined Physiology- concerns the function of the body, how the body parts work and carry out their life-sustaining activities Physiology is explainable only in terms of the underlying anatomy 2. Gross (macroscopic) anatomy- the study of large body structures visible to the naked eye (heart, lungs) relates to the term anatomy most closely Regional: all structures (muscle, bones) in a specific area studied together Systemic: structures studied by system Surface: study of internal structures as they relate to the over lying skin surface (studying externally) Microscopic anatomy- deals with structures too small to be seen with the naked eye Cytology: considers the cells of the body Histology: study of tissues Developmental anatomy- traces structural changes that occur in the body throughout the life span

Embryology- concerns developmental changes that occur before birth 3. See Gross anatomy 4. The principle of complementarity of structure and function is that it is possible to study anatomy and physiology individually, they are really inseparable because function always reflects structure, what a structure can do depends on its specific form 5. Levels of Structural Organization Chemical: simplest, atoms combine to form molecules such as water and proteins, molecules in turn associate in specific ways to form organelles, basic components of the microscopic cells, cells are the smallest units of living things Cellular: all cells have some common functions but individual cells vary widely in size and shape, reflecting their unique functions in the body, the simplest living creatures are composed of single cells but in complex organisms Tissue- groups of similar cells that have a common function, epithelium, muscle, connective tissue and nervous tissue

Organ- discrete structure composed of at least two tissue types that performs specific function for the body, extremely complex functions become possible Organ system- organs that work together to accomplish a common purpose, example: cardiovascular,
