Chapter 1 Flashcards
its the study of internal and external structures of organisms and the relationship of its parts -
anatomy
2 anatomys -
microscorpic anatomy
macroscorpic anatomy
study of structures that need to be magnified
microscorpic anatomy
also called GROSS Anatomy, study of structures that can be seen with the naked eye
macroscorpic anatomy
looking at the levels of organization, what does the existence of life depend on?
proper chemistry
study of the functions of organisms andparts
physiology
structures are designed for ……
specific function
describe what “form follows function” means
structures determine function, and function influences anantomy or organism
survival depends on ….
maintaining constant conditions within the body
“same standing”
relative constancy of the normal bodys internal environment , despite the changes
homeostasis
homeostasis is a ……. process
dynamic
what are 2 feedback loops -
positive & negative
3 basic components of feedback loops -
sensor, control, respond
detects change in specific element and signal control
sensor
it sends signals to effectors
control
respond to integrator
effectors
it opposes change to return to normal (opposite)
negative feedback loop
an ex of negative feedback loop -
increase breathing to replace oxygen
it temporarily amplifies change to return to normal
positive feedback loop
an example of a positive feedback loop -
labor
which type of feedback loop is the most common in the human body
negative
what does disease mean
not at ease
and body does not function normally
its the study of the transmission, frequency, distribution, and control of disease
epidemiology
a disease that can be spread in many ways (person to person, insect to person)
communicable
a disease spread from person to person
contagious
its the study of disease
pathology
causes disease -
pathogenic
an infectious disease from medical facility
nosocomial
it means the cause of the disease is unknown
idiopathic
How do you know when a disease is occuring -
signs
vital signs
symptoms
prognosis
they are objective and measurable
signs
they are signs vital to life … ex. pulse, blood pres. blood temp
vital signs
they are subjective
symptoms
its the prediciton of the outcome of the disease
prognosis
what is anatomical positiion -
standing w aarms @ side, palms forward
patient is on his or her back
supine
patient is on his/her stomach
prone
it is used to show the reader which way the body is posittioned
compass rosette
where the right and left sides are mirror images
bilateral symmetry
where theyre the same side
ipsilateral
