Initial studies on in-utero tracheal occlusion were undertaken by tracheal ligation,111 using clipping of the fetal trachea.
From top left to right bottom: epiglottis, vocal cords, trachea, carina, inflated and detached balloon, vocal cords about to close over the balloon.
All are oriented with the anterior to the right and show the mouthparts, the two dorsal branches of the tracheae and the midgut.
From that point on, the embryos that did not hatch progressed through the stages of brown midgut, brown tracheae and death.
At its upper end, the trachea enters the larynx, which in turn opens into the pharynx.
A femoral vein and the trachea were cannulated.
This nematode was found in the air sacs and trachea in nearly equal numbers (table 1).
The fetal trachea is filled with amniotic fluid, and thus readily seen using sonography.
