Chapter 1 lecture video Flashcards
anatomy
studies form or structure
physiology
examines how the body functions
anatomy and physiology are _______
interrelated
subatomic atoms form
atoms
subatomic particles are
protons, neutrons, and electrons
levels or organization smallest to larges
chemical level-
cellular level
tissue level
organ level
organ system level
organism level
chemical level of organization contains
atoms, molecules, macromolecules
organ system in the human body
integumentary- skin
skeletal system- bonds
muscular system- muscles
nervous system- brain, spinal chord nerves
endocrine system-hormones
cardiovascular system- heart, blood vessels
lymphatic system- immune system and lymphatic vessels
respiratory system-lungs
urinary system-kidney, bladder, urethra
digestive system- abdominal pelvic cavities
male and female reproductive system-
acronym to remember organ systems is
MR DICE Runs or MURDERS LINC
correct anatomical position
standing upright, feet parallel and flat, palms face towards from, arms by sides. and head is level.
slices of the body are called
sections or planes
section def
actual cut of the body that exposesinternal anatomy
plane-
imaginary flat surface passing through body
anterior means
front
posterior
back
coronal plane divideds body to
frontal and exterior portions
transverse-
horizontal dividing top and bottom
dorsal can mean
back
ventral can mean
front
superior means
top or above
inferior means
bottom or below
sagittal planes separates
left and right plans
midsaggital plane
cuts equal left and right planes
proximinal
closer
distal
farther
cephalic is the
head region
cervical
neck
axillary region
armpit
pelvic region
pelvic
cerival region
neck
serous membrans
dual layer membranes with space in between
serous membranes stops
friciton
paritel layer
touches body wall in serious membrane
serious membrane is composed of
parietal and visceral
serious cavity is
the space between the paritel layer and visceral. its a fluid
visceral layer
touches external surface of organs
mediastinum
median space in between thoratic cavity
mediastinum contains
heart, thymus, esophagus, trachea
surrounding heart is surrounded by serous membrane called
pericardium
so serous membrane around heart is called
paritel pericardium and visceral pericardium
pericardial cavity
around heart
serous membran in lungs is called
pleura. visceral pleura, paritel pleura
lung cavity called
pleura cavity
componenrs of homeostasis
receptors, control center, effector
how does homeostasis work
stimuli detect a change (receptor), control center takes this receptor and invokes change through effector, effector makes chanege.
negative feedback
controlls most processes in the body
fluctates- you may have too much of something so body would lower amount to set point.
positive feedback
occurs when speciifc things happen. receive wound ord blood clout. body would have to increase. increase till somehing occurs. for example your body would need to increase variable in order to heal.
