The ends of the villi were enlarged with knob-like processes.
The villi are hypertrophied, looking often like minute polypi.
Collectively, these structures are called the villi (singular villus).
Between the villi are found the openings of the intestinal glands.
Villi are seen surrounded with the openings of the tubular glands.
It is through these villi that the digested food passes into the blood.
The villi are peculiar to these parts; they are inversely conical, adhering to the membrane by their smaller end.
Injections made retrograde from the thoracic duct, pass through the villi into the intestines.
When the allantois adheres to the subzonal membrane vascular processes grow out from it into these villi.
The villi are arranged in ridges which radiate from a non-villous longitudinal strip on the concave surface of the chorion.
