Define Anatomy and Physiology. Relationship between the two
- study of the structure and shape of body and parts
- study of how body and parts work or function
-
Levels of Study- Gross Anatomy
Gross Anatomy; Large structures & Easy observable
Levels of Study- Microscopic Anatomy
Microscopic Anatomy; Very small structires & can only be viewed by microscope
List Levels of Structural Organization smallest to largest
Chemical->Cellular->Tissue->Organ->Organ System->Organism
Integumentary System
- forms external core
-protects internal tissue from damage
-regulates body temperature
-location of nerve receptors
Skeletal System
-protects & support body organs
-where blood cell formation takes place
-provide muscle attachment
Muscular System
-produces movement
-maintains posture
-provides body heat
Nervous System
- fast-acting control system
- responds to internal/external change
- activates muscles & glands
Endocrine System
-secretes metabolism, reproduction, and growth hormones
Cardiovascular System
-transports material in the body using blood from the heart which include O2,H2O, waste, and minerals
Lymphatic System
-cleanses the blood
-involved in immunity
-returns fluid to blood vessels
Respiratory System
-keeps blood supplied with oxygen
-removes carbon dioxide
Digestive System
-breaks down food
-allows for nutrient absorption into the blood
-eliminates indigestible material
Urinary System
-maintians acid-base balance
-regulates water and electrolytes
-eliminates nitrogenous wastes
Reproductive System
-produces offspring
Necessary Life Functions
-metabolism
-growth
-reproduction
-movement
-responsiveness
-digestion
-excretion
Homeostasis
bodys ability to maintain internal stability despite the external activity, It is necessary for normal body functioning. IF** homeostasis is imbalance, the result is disease
Maintaining Homeostasis
Receptor
Control Center
Effector
The body comm. thru neural and hormonal control systems
Receptor responds to changes in envir. & sends info to ctrl cntr.
Effector provides means for response to stimulus
Negative Feedback
Positive Feedback
feedback that makes stimulus eventually stop ex. sweating or shivering
ehances stimulus ex. childbirth of bloodclotting
