Chapter 1: Part 1 Flashcards
study of structure and relationships
anatomy
study of function and how they work together
physiology
individual cells that share common functions
cellular level
atoms combine to form molecules
chemical level
groups of similar cells that have a common function
tissues
structure composed of at least 2 tissue types
organ
organs that work together
organ system
sum of all total organ systems that keep us alive
organism
inside and outside environments are seperate
maintaining boundries
activities that are promoted by the muscular system
movement
the ability to sense changes in the environment
responsiveness/excitability
the break down of food intake
digestion
all chemical reactions that occur within body cells
metabolism
removing wastes from the body
excretion
to replicate or reproduce
reproduction
increase of an organism as a whole
growth
energy substance
nutrients
this releases the energy from foods that we eat
oxygen
the medium for chamical reactions in the body: 50-60%
water
must maintain this for chemical reactions
normal body temperature
needed for proper gas exchange in the lungs
atmospheric pressure
how is anatomy and physiology related
they are interrelated, must know one in order to use the other
levels of structural organization, simplest to most complicated
chemical, cellular, tissues, organ, organ system, organism
what are the 8 necessary life functions
maintaining boundaries, movement, responsiveness, digestion, metabolism, excretion, reproduction and growth
