Chapter 1 Flashcards
Anatomy
Study of internal and external structures
Subsets of anatomy
Gross anatomy
Microscopic anatomy
Physiology
How living organisms perform vital function
Subsets of physiology
Cell, systemic, special, and pathophysiology
Structure and function
All specific functions are performed by specific structures
-altering the structure will alter function
Atoms
Smallest stable units of matter, building blocks for everything we will discuss
Molecular
Atoms join to form molecules, functional properties are determined by shape
Cellular
Smallest living structural and functional unit of the body
Tissue
Group of cells working together to perform specific functions
Organ
2 or more tissues organized to perform specific functions
Organ system
Interaction of organs and tissues for a common purpose
Whole organism
Human being, needs all 11 systems working for life and health
Integumentary
Protection from environment/ regulate temp/ sensory info
Organs- skin hair and nails
Skeletal
Support and protect/ mineral storage
Organs- bone, cartilage, and ligaments
Muscular
Movement/protection and support/ body temp
Organs-muscle and tendons
Nervous
Coordinates organ systems/response to stimuli
Organs-brain, spinal cord, nerves
Endocrine
Coordinated organ systems/ metabolic activity and development
Organs- pituitary gland, sex gland
Cardiovascular
Distributes blood
Organs-heart, vessels, blood
Lymphatic
Retains fluid/ immune system
Organs- spleen, lymph nodes
Respiratory
Provides O2 to blood/ communication/ balance pH
Organs-lungs and trachea
Digestive
Digests food/ absorbs nutrients
Organs- stomach, liver, intestines
Urinary
Removes waste/ controls water loss
Organs- kidneys bladder
Male reproductive
Produce spend and make hormones
Testes
Female reproductive
Produce egg/ female hormones/ support infant
Ovaries, uterus
Homeostasis
Existence of a relatively stable eternal environment
Disorder
Any abnormality if structure/function
Disease
A disorder characterized by a set of signs and symptoms
Auto regulation
Occurs when a cell or system adjusts its activities automatically
Extrinsic regulation
When the nervous or endocrine systems cause a change in activities
Nervous system
Reacts quicker>specific>short lived
Endocrine system
Reacts slower>wide ranging>lasts longer
Receptor
Senses a change in a particular parameter, stimulus
Control center
Receives and processed info from receptor, directs a change
Effector
Responds to command, can oppose or enhance stimulus
