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 fins are supported by rays, as the name indicates. In contrast to the cartilaginous fish they have a rigid skeleton.The swim bladder is also a unique feature of most ray-finned fish, enabling them to maintain buoyancy as they move up or down in the water.A gill cover is used to pump water through the gills, enabling the bony fish to breathe without swimming.he fins are supported by rays, as the name indicates.
