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.
The 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 :).he gills are the equivalent of our lungs. Basically they absorb Oxygen from the water flowing over them and at the â¦ same time they remove Carbondioxide and other nasties they don't need or want from the blood stream. 7 people found this useful.
