It helps in diagnosing abnormalities in pregnancy, including preeclampsia (which is a dangerously high blood pressure during pregnancy) Along with AFP and uE3, inhibin A and inhibin B levels are also measured as a second-trimester screen for Down syndrome
A gill (/É¡Éªl/) is a respiratory organ found in many aquatic organisms that extracts dissolved oxygen from water and excretes carbon dioxide. The gills of some species, such as hermit crabs, have adapted to allow respiration on land provided they are kept moist.
