Chapter 1Introduction to Human Anatomy
and Physiology
Anatomy and Physiology
Anatomy – study of structure/ location
Physiology – study of function
Structure is always related to function
Levels of Organization
Levels of Organization
Organelle – mitochondrion, nucleus
Cell – bone building cell (osteoblast)
Tissue – bone (connective tissue)
Organ – thigh bone (femur)
Organ System – skeletal system
Organism - human
Homeostasis
Body’s maintenance of a stable internal environment
Homeostatic Mechanisms – monitor aspects of the internal environment and corrects any changes
•Receptors - provide information•Control center - tells what a particular value should be•Effectors - causes responses to change internal environment
Organ Systems
Organ Systems
Organ Systems
Anatomical Terminology
Anatomical Position – body standing erect, facing forward, upper limbs at the sides, palms facing forward
Terms of Relative Position• Superior versus Inferior•Anterior versus Posterior•Medial versus Lateral•Ipsilateral versus Contralateral•Proximal versus Distal•Superficial versus Deep
Body Sections
Body Cavities
Body Cavities
Right and left are always reversed in anatomical drawings!
Middle of sternum(heart, trachea, esophagus)
Serous Membranes
Thoracic Membranes•Visceral pleura•Parietal pleura•Visceral pericardium•Parietal pericardium
Visceral layer – covers (touches) an organParietal layer – lines a cavity or body wall
Abdominopelvic Membranes•Visceral peritoneum•Parietal peritoneum
Serous Membranes
Serous Membranes
Body Regions
These are the words we play Taber says with
