Bodily functions Flashcards
Mitosis
When the Nucleus of the cell divides
Organelles
Structures found within cytoplasm
Chromosomes
Carry genes that determine hereditary characterisitics
Neurons
Nerve Cells
Molecule
Chemical combination of 2 or more atoms form a specific compound
Negative Feedback
Body responds to external stimuli by reversing direction of change
Nucleus
Responsible for cells growth, metabolism and reproduction
Organs
formed by similarly functioning tissues
Osmosis
diffusion where water is pulled through semipermeable membrane
Passive Transport
process in cells that does not require energy to transport to, from and within
Pathophysiology
study of diseases and disorders
Physiology
Study of the function of an organism
Positive feedback
encouraging external or internal stimuli to continue or accelerate
Deoxyribonuleic Acid
Cells Genetic Makeup
Ribonucleic Acid
single chain of chemical bases
Systems
organ group that works together to perform a function
Striated Muscle tissue
Voluntary Muscle
Tissues
Cell groups that perform a special function
Genetics
study of makeup of animals or plants
heredity
genetic makeup from parent to child
homeostasis
body works to maintain balance
cytokinesis
cytoplasm divides into two identical daughter cells
anatomy
body structure of organism
active transport
body requires energy to move to and from cells
cell membrane
outer covering of cell
cell
basic unit of life
cilia
hair like projections that cover cell
congenital disorder
genetic disorder formed during pregnancy
gametes
where chromosomes reduce from 46 to 23
atom
consist of at least one proton
meiosis
cells reduce chromosomal # by half to form gametes
flagella
tail like structures that allow cell to move
filtration
pressure to diffuse particles through membranes
electrolyte
molecule that conducts electricity
diffusion
moving particles from greater area of concentration to area of lesser
