    Tissues:

    Cells are organized into four basic types of tissues that perform specificfunctions

    1. Epithelial tissues Epithelial tissue covers and protects body structuresand lines organs, vessels, and cavities.

    2. Connective tissue Connective tissue supports and binds body structures.

    It contains fibers and other nonliving materialbetween the cells. Examples are adipose (fat) tissue,cartilage, bone and blood

    3. Muscle tissues Muscle tissue (root my/o) contracts to produce

    movement.

    4. Nervous tissue Nervous tissue (root neur/o) makes up the brain,spinal cord, and nerves. It coordinates and controlsbody responses by the transmission of electricalimpulses.

    Tumor talkAdding - oma (a swelling) to organ and tissue word roots names tumors. Not all tumors

    Aden/o = gland

    adenoma

    Lip/o = fat

    lipoma

    My/o = muscle

    myoma

    Lymph/o = lymph tissue

    lymphoma

    Carcin/o = malignant carcinoma
