They secrete chemical (hormones) that affect the body’s functioning. One of these hormones is adrenaline (epinephrine). It causes the bronchial tubes to widen, the heart to beat more rapidly, and blood pressure to rise. anameans up, apart ante means before, forward antimeans against Example For Example: An antibiotic destroys or inhibits the growth of microorganisms (small living things) such as bacteria. Penicillin, the first antibiotic, was cultured from immature plants (molds) and found to inhibit bacterial growth. Antigens, Antibodies and the Immune Response An antigen is a substance, usually foreign to the body such as a poison, virus or bacterium), that stimulates the production of antibodies. When you receive a vaccine, it contains dead or weakened antigens that stimulate lymphocytes to make antibodies, which remain in your blood to protect against those specific antigens when encountered later on. Antibodies are protein substances made by white blood cells in response to the presence of foreign antigens Another Example of an antigenantibody is the Rh condition A person who has is Rh positive (Rh+) has a protein coating (antigen) on his or her red blood cells (RBCs). This specific antigen factor is something that the person is born with and is normal. People who are Rh negative (Rh-) have normal RBCs as well, but their red cells lack the Rh factor antigen. If an Rh- woman and an Rh+ man conceive an embryo, the embryo may be Rh- or Rh+. A dangerous condition arises only when the embryo is Rh+ (because it is different than the mother) autobibradycatacon- means means means means means self, own two slow down with, together contra – dediadys- against, opposite down, lack of through, complete bad, painful, difficult, abnormal ec-, ectoout, outside For Example: Ectopic Pregnancy - Ectopic means pertaining to out of place and modifies the noun “pregnancy”. en-, endoepieuexhemihyperhypoininfrainterintramacro mal- in, within upon, on, above good, normal out, away from half excessive, above deficient, under not, into, within beneath between into, within large bad meta microneopanparaperperipolypostprepropseudo- beyond, change small new all abnormal, beside, near through surrounding many, much after, behind before, in front of before, forward false reback, again retrobehind, backward subunder supraabove, upper syn, symtogether, with For Example: The pubic symphysis is located where the pelvic bones come together. Tachyfast Transacross, through For Example: Transurethral resection of the prostate gland (TURP), a portion of the prostate gland is removed with an instrument (rectoscope) passed through (trans-) the urethra. The procedure is indicated when prostatic tissue increases and interferes with urination. The prostate gland is located at the base of the urinary bladder.
