Chapter 1: An Introduction to Anatomy & Physiology Flashcards
anatomy
to cut open, study structures and physical relationships among body parts
gross anatomy
see with the eye
microscopic anatomy
can’t see w/o microscope
physiology
study of function and how organism perform vital functions
common characteristics (7)
cells, organization, responsiveness, regulation, growth and development, reproduction, metabolism
chemical level
atoms and molecules, basis for how everything works, simplest
cellular level
cell, basic unit of life, building blocks
tissue level
epithelial, connective, muscle, nervous
histology
study of tissues
cytology
study of cells
organ level
composed of 2 or more tissue levels
organ system
11 systems
organism
organ system will make up organism
integumentary system
skin, protects against environmental hazards, helps control body temperature
skeletal system
provides support, protects tissue
muscular system
produces movement, generates heat
nervous system
directs immediate responses to stimuli
endocrine system
directs long-term changes in other organ systems w/ hormones
cardiovascular system
transports cells
lymphatic system
defends against infection and disease
respiratory system
delivers air
digestive system
processes food
urinary system
how we get rid of waste
reproductive system
produce sex cells and hormones
homeostasis
maintaining a stable internal environment
3 parts of homeostasis
receptor, control center, effector
negative feedback: effector ______ or _______ the original stimuli
opposes or negates
postitive feedback: response _______ or _______ original change
exaggerates or enhances
postitive feedback does not
restore homeostasis
anatomical position
standing up, hands by side, palms and feet foward
supine
face up
prone
face down
RUQ
right upper quadrant
liver, gallbladder, large intestine
LUQ
left upper quadrant
stomach, spleen, large intestine
RLQ
right lower quadrant
appendix
LLQ
left lower quadrant
small intestine and part of large intestine
The 9 abdominopelvic regions help
describe more precise location
anterior or ventral
front
posterior or dorsal
back
superficial
close to skin
deep
farther from skin
proximal
close to point of attachment
distal
farther from point of attachment
superior
closer to head
inferior
towards feet
frontal
divides anterior from posterior
sagittal plane
divides from left from right
transverse
divides superior from inferior, cross section, inferior view
body cavities are covered by
serous membranes
body cavity functions
protects organs from shock and permits changes
The thoracic and abdominopelvic cavity is separated by
the diaphragm
properties of water
lubrication, chemical reactant, high heat capacity, solvent
acidic level
below 7
neutral level
equals 7
alkaline level
above 7
monosaccharide
glucose
