Chapters 3,4,5

absorption the taking in of materials by cells or tissues
active transport the movement of materials through a cell membrane using energy from a lesser concentration to a greater concentration
adipose(fat) stores excess fat cushions generates heat
areolar(loose) subcutaneous connects skin to muscle
blood plasma-transport materials RBCs- carry oxygen WBCs-destroy pathogens platelets-prevent blood loss
bone -supports the body -protects the internal organs from mechanical injury -stores excess calcium -contains red bone marrow
cartilage -keeps airway open -smooth to prevent friction -supports, maintains shape -absorbs shock,permits movement
cell smallest living unit in the body
centrioles organizer of spindle fibers for the distribution of chromosomes during cell division
cereumen earwax
cilia sweep materials across the cell surface
cilitated epithelium the tissue that has motile cilia on the free surface of the cell
columnar tall and narrow
connective tissue tissue that connects, support, transport, or stores materials
cuboidal cube shaped
cytoskeleton gives shape to the cells, and contributes to the movement of the cell
dehydration lack of water
dermis inner layer of skin
diffusion movement of molecules from an area of higher concentration to an area of lower concentration
elastic within the walls of large arteries- help maintain blood pressure around alveoli in lungs-promote normal exhalation
Endoplasmic Reticulum (ER) passageway for transport of materials within the cell
epidermis outer layer of skin
epithelial tissue coverings and lining
facilitated diffusion(help or assist) the transport of substances through a cell membrane along a concentration gradient with the aid of carrier protein
fibrous -tendons and ligaments -strong to withstand force -dermis-strong inner layer of skin
filtration(push through) the process in which water and dissolved materials move through a membrane from an area of higher pressure to an area of lower pressure
flagellan long appendage that enables a cell to move(sperm cell)
glands a cell, a group of cells or an organ that produces a secretion for uses elsewhere in the body or in a body cavitiy or the elimination from the body
Goblet cell secretes mucus
Golgi Apparatus packaging of materials for secretion from the cell
hair follicles structure within the skin in which the hair grows
hair root new cells grow
hair shaft push through the surface of the skin
lysosomes container of enzymes that digest ingested foreign material such as bacterial or digest and recycle damaged tissue or cellular parts
meiosis(twice to four cells) the process of cell division in which one cell with the diploid number of chromosomes divides twice to form four cells, each with haploid number of chromosomes
melanocytes produce melanin
membranes thin layers of tissues that cover a surface, line a cavity, or divide a space or an organ
microvilli folds of membranes of a cell that increase its surface area
mitochondria site of aerobic respiration; production of ATP
mitosis the process of cell division in which one cell with the diploid #of chromosomes divides once to form two identical cells, each with diploid # of chromosomes
mucous membrane line the body tracts that have openings to the environment
mucous keeps the cell wet
muscle tissue contraction
nail follicles produce nails
nail root portion of the nail buried in fold of skin
nucleus double-layered nuclear membrane with many pores
osmosis diffusion of water
pilomotor muscle that causes erection of hairs on skin
pleural membrane serous membrane that enclose the lungs and line the chest wall
receptors specialized cell or nerve ending that responds to a particular change such as light,sound,heat,touch or pressure
ribosomes site of protein synthesis
sebaceous glands oil glands
selectively permeable some substances can pass across them and others cannot
serous membrane a thin membrane lining that a closed cavities of the body
simple single layer of cells
simple squamous epithelium single layer of flat cells
skeletal muscle straited/voluntary
simple cubiodal epithelium single layer of cube shaped cells
smooth muscle involuntary/visceral
squamous flat cells
stratified many layers of cells
stratified consists of many layers of flat cells
stratum corneum outer most layer of epidermis
stratum germinatium new cells grow
tissue a group of similar cells that perform the same function
transitional epithelium stratified epithelium in which the surface cells change shape from round to squamous
