Document Summary

Noninvasive diagnostic disease one that does not involve insertion of an instrument or device through skin or body opening. Iodine-131 used to detect thyroid cancer & to assess its size/activity; used to destroy part of overactive thyroid gland: cesium-137 used to treat advanced cervical cancer. 3. 3 medical uses of isotonic, hypertonic, and hypotonic solutions. Isotonic solution any solution that maintains its normal shape & volume: solutes can not cross plasma membrane due to equal concentration of solutes on both sides of membrane in this solution. Hypotonic solution solution that has lower concentration of solutes than cytosol inside cells: water moves into cells faster than water leaves rbcs swell rbcs burst (lysis) Hypertonic solution solution that has higher concentration of solutes than cytosol inside cells: water moves out of cells faster than water cells enter cells shrink (crenation) Under certain conditions, basement membranes become markedly thickened d/t increased production of collagen & laminin.
