A&P Flashcards
Name all Organ systems
DERMIS CLURN
Integumentary, Muscular, Skeletal, Urinary, Digestive, Cardiovascular, Respiratory, Reproductive, Endocrine, lymphatic, Nervous
Level of Organization IN ORDER
mini DEF.
- Atoms- smallest stable units of matter ;forming blocks
- Molecular (chemical) - atoms join to form molecules; determine by shape
- Cellular LEVEL- Smallest LIVING Structure; functional unit of the body
- Tissue LEVEL- groups of cells working together to perform several functions
- Organ LEVEL- 2 or more tissues organized to perform several functions
- Organ System LEVEL- interaction of organs & tissues for common purpose
- Whole Organism- human beings. need all 11 systems.
What is Anatomy?
Study of internal and external structures
What is Physiology?
how living organisms perform vital functions
Explain Structure and Function
Structure dictates Function
Altering the Structure alters the Function
Specific Functions are performed by Specific Structures
Integumentary System, FUNCTION? MAJOR ORGAN?
Protection from environment/regulate temp/sensory info.
Skin , Hair , Nails
Skeletal System ,FUNCTION? MAJOR ORGAN?
Protection, Support,& mineral storage ie. Phosphate and calcium
Bone, Cartilage, ligaments
Muscular System ,FUNCTION? MAJOR ORGAN?
Movement, Protection Support&Body Temp
muscles &tendons
Nervous System ,FUNCTION? MAJOR ORGAN?
Coordinates organ systems/ Response to STIMULI
Brain, spinal cord, nerves
Existence of a STABLE ENVIRONMENT?
Homeostasis
Physiological systems work together to maintain?
Homeostasis
Abnormality of structure or function is?
Disorder
What is a disease?
a disorder characterized by a set of signs and Symptoms
Which systems regulate homeostasis?
Nervous & Endocrine
Autoregulation?
- occurs when cells or systems adjusts its activities automatically
when the nervous or endocrine systems cause a change in activities
Extrinsic Regulation
NERVOUS SYSTEM
(PHONE)
REACTS QUICKER SPECIFIC
SHORT LIVED
REACTS SLOWER WIDE RANGING LASTS LONGER
(MAIL- 1000 POST CARDS)
ENDOCRINE SYSTEM
- senses a change in a particular parameter, stimulus?
- receives & processes information from receptor, directs a change ?
- responds to command, can oppose or enhance stimulus?
Receptor
Control Center
Effector
*Stimulus produces a response that opposes or stops original stimulus
*Tends to minimize change (dynamic/range)
Ex) temperature, blood sugar, most systems
*
*Feeding girl’s plate every time she ate the same amount
negative feedback
Stimulus produces a response that increases or enhances original stimulus
Tends to produce extreme responses
Ex) child birth, blood clotting
Positive feedback
Dynamic Equilibrium?
*Body is continually ADJUSTING & ADAPTING
Requires coordinated efforts of multiple systems
Effects every cell and tissue
