Intro A&P 1 Flashcards
anatomy
the study of internal and external structures of the body
-what they are made of
-where they are located
-how they are associated with each other
physiology
the study of functions of anatomical structure
-what the body does
-includes individual and cooperative functions
atomic level (LOO)
smallest unit of an element that maintains its properties
molecular level (LOO)
-combined atoms
-different properties than single atoms
(combining changes the properties)
cellular level (LOO)
-smallest unit where life occurs
-performs specific functions
tissue level (LOO)
-group of cells working together
-the group of cells perform a function
(divided into four different groups that perform various functions)
organ level (LOO)
-two or more different types of tissues that are combined to form different tasks
(often perform multiple tasks)
organ system level (LOO)
-groups of organs
-perform generalized set of functions
(multiple functions that work with different systems for other functions)
organismal level (LOO)
-organ systems work together to maintain homeostasis
digestive system
-food processing
-water/nutrient absorption
cardiovascular system
-distributes cells, gasses, chemicals, and wastes
-temperature control
urinary system
-removal of liquid waste
-regulates water balance
endocrine system
-body regulation
-directs long-term changes (ex. development)
(hormone control, growth, etc. ; a lot of the glands in here excrete through blood)
respiratory system
-gas exchange
-communication
nervous system
-communication
-body control
-detects/interprets sensory input (more immediate response to changes)
