    #17 testing the basics

    Advertisements



    We are in kidneys so lets continue



    Which of the Following changes does not occur when the efferent arteriole contrancts?


    1-Oncotic pressure in the efferent arteriole decrease
    2-RPF decrease
    3-Glomerular Capillary Hydrostatic preassure increase













    When the efferent arteriole contratcs, hydrostatic preassure in the glomerular capilary rises. This effect tends to increase glomerular filtration rate(GFR), WHILE decreasing RPF leading to an increase of the fitration fraction. Because a greater proportion of plasma is filtered, the plasma proteinpresent in the glomerular capillary become more concentratedand oncotic preassure rise.
