anatomy
the study of structures or morphology of the human body and parts; this came from greek for " a cutting up."
physiology
the study of the functions of the human body and it's parts; came from greek for "relationship to nature."
subatomic particles
protons, neutrons, and elections
atoms
small particles that make up particles- hydrogen, carbon
molecules
particles consisting of molecules- water, glucose
macromolecule
large particles consisting of molecules- DNA, protein
organelle
functional part of a cell- mitochondrion, lysosome
cell
basic unit of structure and functions- muscle, nerve, or blood cell
tissue
layer or mass of cells with specific functions- adipose, tissue
organ
group of different tissues with a function- heart, kidney, stomach
organ system
group of organs with common functions- digestive system
organism
composed of organ system interaction- human
the cell
all living things consist of cells
internal enviroment
environment with body
homeostasis
maintenance of constant internal environment
interdependency of cell
cells depend on each other
structure and functions
interrelated
gradients and permeability
cells move from high to low down pressure and concentration gradients, across permeable membrane
cellular differences
specialization of cells due to gene expression
cell membrane mechanisms
determine entry of substances, respond to signals
cell to cell comunication
via membrane receptors
feedback loops
homeostasis mechanisms for stability
balance
replacement of lost substances, elimination of excesses
energy processes
keeps cells activeanatomy
