Decreased ,vascular ,and ,lymphatic ,pressure ,does ,not ,generally ,result ,in ,the ,movement ,and ,accumula
tion ,of ,fluid ,into ,extravascular ,spaces. ,Increased ,plasma ,pressure ,in ,the ,vascular ,results ,in ,hypertens
ion, ,while ,increased ,lymphatic ,pressure ,will ,readily ,result ,in ,the ,pooling ,of ,lymphatic ,drainage ,into ,t

etion ,of ,mitosis ,or ,meiosis. ,Interphase ,is ,the ,longest ,period ,that ,a ,cell ,spends ,its ,life ,cycle ,and ,is ,th
e ,preparatory ,stage ,before ,cellular ,reproduction. ,Anaphase ,is ,the ,separation ,of ,genetic ,materials ,to ,
the ,opposing ,centromeres ,of ,the ,cell, ,followed ,by ,telophase.
