Red blood corpuscles (Physiol.), in man, yellowish, biconcave,
circular discs varying from 1/3500 to 1/3200 of an inch in diameter
and about 1/12400 of an inch thick. They are composed of a colorless
stroma filled in with semifluid hæmoglobin and other matters. In most
mammals the red corpuscles are circular, but in the camels, birds,
reptiles, and the lower vertebrates generally, they are oval, and
sometimes more or less spherical in form. In Amphioxus, and most
invertebrates, the blood corpuscles are all white or colorless.
– White blood corpuscles (Physiol.), rounded, slightly flattened,
nucleated cells, mainly protoplasmic in composition, and possessed of
contractile power. In man, the average size is about 1/2500 of an
inch, and they are present in blood in much smaller numbers than the
red corpuscles.
