    anatomy- the science of the structure of living organisms

    physiology- the science of the functioning of living organisms

    cell- the basic biological unit of living organisms, containing a nucleus and a variety oforganelles enclosed by a limiting membrane

    tissues- a group of similar cells specialized to preform a specific function; primarytissue types are epithelial, connective, muscle, and nervous tissues

    organ- a part of the body formed of two or more tissues that preforms a specialized

    function

    organ system- a group of organs that work together to preform a vital body function! -Integumentary- skin! ! -protection! -Skeletal- bones, cartilages, ligaments, and joints! ! -supports and protects! -Muscular- muscles! ! -movement! -Nervous- brain, spinal cord, nerves, and sensory receptors! ! -fast acting control! -Endocrine- hormones! ! -regulate body! -Cardiovascular- heart and blood vessels! ! -transports oxygen in blood! -Lymphatic- lymphatic vessels, lymph nodes, spleen, and tonsils! ! -cleans blood, houses immunity cells (think lysol)! -Respiratory- nasal passages, pharynx, larynx, trachea, bronchi, and lungs! ! -supplies body with oxygen! -Digestive- mouth, esophagus, stomach, small and large intestine, and rectum! ! -breaks down food for absorption! -Urinary- kidneys, ureters, bladder, and urethra! ! -removes nitrogen wastes! -Reproductive- male- penis ; female - vagina! ! -produce offspringorganism- an individual living thing

    homeostasis- a state of body equilibrium or stable internal environment of the body

    melanocyte- a cell that produces melanin

    melanin- the dark pigment synthesized by melanocytes; responsible for skin color

    keratin- a tough, insoluble protein found in tissues such as hair, nails, and epidermis ofthe skin; waterproof

    sweat glands- secrete sweat

    apocrine glands- less numerous sweat gland; salt, water, protein; BO- armpits/ gooch

    eccrine glands- sweat gland; salt and water

    sebaceous glands- secretes oils; attached to hair follicle;

    hair follicles- surrounds hair shaft int he dermis

    sensory receptors- nerve endings in the skin

    papillary layer- dermal papili; causes finger prints

    hair bulb- bulb at the bottom of the hair shaft

    sebum- the oily secretion of sebaceous glands

    Burns-1st degree- sunburn, mild; epidermis damage and redness! 2nd degree- bad sunburn; epidermis and dermis damage; partial thickness;! ! ! most painful! 3rd degree- black, grey, white; full thickness; skin grafting;! ! ! painlessacne- inflammatory disease of the skin; infection of the sebaceous glands
