---|---|
diffusion of molecules requiring carrier enzymes | facilitated diffusion |
the engulfing of something by a moving cell | phagocytosis |
the engulfing of something by a stationary cell | pinocytosis |
the diffusion of water through a semi-permeable membrane | osmosis |
the movement of molecules from an area of greater concentration to an area of lesser concentration | diffusion |
water and dissoved materials move through a membrane from an area of higher pressure to an area of lower pressure | filtration |
the use of energy to move molecules from an area of lesser conventration to an area of greater concentration | active transport |
columnar cells with cilia on their free surface | ciliated epithelium |
many layers of cells, surface cells are alternating round or flat permits streching | transitional epithlium |
one layer of flat cells forming the alveoli of the lungs, capillaries and permits gas exchange | simple squamous |
many layers of cells with cell surface being flat, forming epidermis of the skin and the lining of the mouth and esophagus | stratified squamous |
one layer of cube shaped cells | simple cuboidal |
one layer of cells that are taller than they are wide | simple columnar |
carries impulses from cell body | axon |
carries impulses toward the cell body | dendrite |
contains nucleus | cell body |
unicellular gland that consits of only one cell | goblet cell |
in tendons and ligaments and are strong to withstand forces of movement | fibrous connective tissue |
withing the walls of the trachea and supports to keep the airway open | cartilage |
in the subcutaneous and stores excess energy and helps cushion eyes and kidneys | adipose tissue |
within blood vessels and carries various cells and transports materials | blood |
wall of large arteries to help maintain blood pressure and in lungs to promote normal exhalation | elasic connective tissue |
in subcutaneous and connect skin to muscles and has WBC to prevent pathogen entry | areolare conective tissue |
supports the body and protects internal organs and stores calcium | bone |
glands that have no ducts | endocrine |
glands that have ducts | exocrine |
one diploid cell divides into two cells with 46 chromosomes | mitosis |
one cell divides twice into four haploid cells | meiosis |
arterioles in the dermis constrict to decrease the blood flow | vasoconstriction |
air currents move warmer air away from the skin suface ancd facilitate heat loss | convection |
heat from the body is transferred to cooler objects not touching the skin | radiation |
the loss of heat to cooler air or objects that touch the skin | conduction |
changing water to vapor on the skin surface to fcacilitate heat loss | evaporation |
arterioles in the dermis dilate or expand to increase blood flow | vasodilation |
fomation of molecules into larger ones | anabolism |
decomposition of molecules | catabolism |
all of the reactions that take place in the body | metabolism |
carry a positive charge | cations |
carry a negative charge | anions |
excessive H+ ions are retained | metabolic acidosis |
co2 is not exhaled and increases in the body | respiratory acidosis |
thereis a decreased of h+ ions | metabolic alkalosis |
co2 is exhaled excessively and causes hyperventilation | respiratory alkalosis |
caused by external factors such as viruses, chemical, or radiation exposure | mutations |
determining the priority of care | triage |
severe systemic allergic response which left untreated can result in death | anaphylaxis |
sudden onset severe in intensity and usually short in duration | acute |
less severe and has a duration longer than six months | chronic |
comes and goes and usually has a brief duration and is not often isgnificant | transient |
usually generated by nerve damage | intractable |
simple single celled organism found everywhere | bacteria |
not celled require a living cell to enter and to reproduce | virus |
single celled animals most live in water | protozoa |
unicellular or multicellular structure which decompose matter in soil | fungi |
multicellular animals free lining and non pathogenic | worms |
multicellular animals which serve as vectors | arthropods |
natural population of microorganisms living on or in us | normal flora |

bacteria that are found periodically on or in body | transient flora |
symptoms are evident | symptomatic |
no symptoms evident | asymptomatic |
