Lecture 1 Anatomy & Physiology

Anatomy & Physiology An Introduction

Introduction ► Anatomy

 Anatomy derived from Greek words meaning to cut (tomy) apart (ana).  Anatomy (ah-nat’o-me) is the study of structure and shape of the body and body parts and their relationships to one another. ►Gross Anatomy ►Microscopic Anatomy

(Heart, Bones) (Cells, tissues)

Introduction ►

Physiology  

physio = nature, ology = the study of Physiology (fiz”e-ol’-je) is the study of how the body and its parts work or function

► Many

Branches e.g.

 Neuro physiology  Cardiac physiology

Relationship between anatomy and physiology ► Always

an inter-relationship---? ► Parts of the body form a well organized unit and each of those parts has a job to do to make body operate as a whole. ► Structure determines what can be done. ► For example ???? ► Lungs are not muscular Chamber like heart so they cant pump blood but with very thin sac walls can exchange gases and provide O2 to body.

Level of Structural Organization

Level of Structural Organization ► Chemical

Level (Atoms  Molecules) ► Cellular Level (Molecules  Cells) ► Tissue Level (Cells  Tissues) ► Organ Level (Tissue  Organ) ► Organ system level  Organs together  Organ system ► Organism

Level

 Organ Systems Together  Organism Level
