The Inhibins A and B Blood Test helps determine the levels of inhibin A and inhibin B in blood. 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.
Two functions of a clam's gills are to extract oxygen from the water and separate sand particles from food particles and water when being digested.he gill filaments are the hair-like structures on the gills which absorb the oxygen from the lamallae. The gill arch, on the other hand, acts as a form of muscle which holds â¦ the structures of the gills together. ~Sincerely, A Smarty pants :). + 21 others found this useful.
