- Front
- Back
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 |
