Introduction to Anatomy and Physiology

anatomy

form and structure �microscopic anatomy �macroscopic (gross) anatomy �regional anatomy �systemic anatomy

physiology

functions

macroscopic anatomy

seen with unaided eye �organs �muscles �bones

microscopic anatomy

seen with a microscope �cells �tissues

systemic anatomy

individual systems
� skeletal system � integumentary system � nervous system � cardiovascular system � respiratory system � digestive system � muscular system � sensory system � endocrine system � urinary system � reproductive system

regional anatomy

individual region
� neck or abdomen, etc. cells tissues blood vessels nerves muscles organs bones

Bilateral Symmetry

The left and right halves of an animal's body are essentially mirror images of each other.

dorsal cavity

central nervous system �cranial cavity �spinal cavit

ventral cavity

thorax and abdomen �viscera

thorax = chest

cranial thoracic cavity �major structures �heart �major blood vessels �lungs �esophagus

abdomen

caudal abdominal cavity �major structures �digestive organs �urinary organs �reproductive organs

Lining Membranes-abdominal cavity

peritoneum �visceral layer �potential space �parietal layer

Lining Membranes-thoracic cavity

pleura �visceral layer �potential space �parietal layer

Lining Membranes-pleura

thoracic cavity �inflammation �pleuritis / pleurisy

Lining Membranes-peritoneum

abdominal cavity �inflammation �peritoniti

Organization of the Body

cells tissues organs systems

Levels of Organization-cells

basic units of life �specialized function

Levels of Organization-tissues

epithelial tissue �connective tissue �muscle tissue �nervous tissue

Levels of Organization-organ= groups of tissues that work together

�single structures �brain �heart �uterus
�occurring in pairs �eyes �lungs �kidneys

Levels of Organization-systems = groups of organs

involved in common set of activities �example is digestive system oobtaining food odigesting food oabsorbing nutrients

Health

a state of normal anatomy and physiology

Disease (Pathology)

the result when structures or functions of the body become abnormal

Homeostasis

maintenance of dynamic equilibrium
responsibility of the entire body all physiological processes maintain the body's balance in the various: �structures �functions �properties
makes life possible
