Week 1 Flashcards
Anatomy
Structure
Cytology
Anatomy of Cells
Histology
Anatomy of Tissues
Physiology
Function of the body/ “how”
Homeostasis
-Steady state of internal conditions
-Body uses feedback to maintain steady state
6 Levels of Organization
- Chemical
- Cellular
- Tissue
- Organ
- Organ System
- Organism
11 Organ Systems
- Integumentary
- Skeletal
- Muscular
- Nervous
- Endocrine
- Cardiovascular
- Lymphatic
- Respiratory
- Digestive
- Urinary
- Reproductive
Function of the Integumentary System
- 1st line of defense
Function of the Skeletal System
-Supports
-Protects
-Makes blood cells
-Storage
Function of the muscular system
-Supports
-Movement
-produces heat
Function of the Nervous System
-Coordinating activity
-Responds to feedback
Function of Cardiovascular System
Transports gases, nutrients, wastes, water & hormones
Function of Lymphatic System
-Fights infection
-regulates fluids
Function of Endocrine System
Regulates body functions using hormones
Function of Respiratory System
-Gas exchange (O2/CO2)
-Talking
Function of Digestive System
-Takes in nutrients
-Removes Wastes
Function of Urinary System
-Removes wastes
-regulates water
-controls pH
Function of Reproductive System
-Growth (puberty)
-Reproduction
Compartmentalization
-Keeps cells separate from threat
-Keeps them moist/nourished
Metabolism
sum of ALL reactions in the body
Anabolism
-Requires Energy
A=Add
Catabolism
-Releases Energy
C=Cut
Hyperplasia
increase in NUMBER of cells
Hypertrophy
increase in SIZE of cells
Requirements for Human Life
-Oxygen
-Nutrients
-Narrow range of temperature
-Narrow range of pressure
Negative Feedback Loop
RETURNS body to homeostasis
Positive Feedback Loop
-Exacerbates the initial stimulus
-moves AWAY from homeostasis
4 Parts of a Feedback Loop
- Stimulus
- Sensor
- Control
- Effector
Serous Membrane
-Surrounds Organs
-Produces fluid/lubrication
-Protects organs/provents friction
