The morphology of the pecten oculi of the ostrich, Struthio camelus
(2006)
The pecten oculi is a structure peculiar to the avian eye. Three morphological types
of pecten oculi are recognized: conical type, vaned type and pleated type. The
pleated type has been well studied. However, there exists ...
The morphology of the gills of the freshwater African crab Potamon niloticus (Crustacea: Brachyura: Potamonidae): A scanning and transmission electron microscopic study
(Wiley, 1990)
The gills of the African freshwater crab Potamon niloticus-Ortmann have been investigated by scanning and transmission electron microscopy. Potamon has seven pairs of phyllobranchiate gills contained in the branchial ...
The thickness of avian blood-gas barrier: qualitative and quantitative observations.
(1982)
Gas exchange in the avian lung takes place across a blood-gas barrier formed, as
in other air-breathing vertebrates, by three essential components, an epithelial cell,
a basal lamina, and an endothelial cell. The thickness ...
Morphometrics of the avian lung. 3. The structural design of the passerine lung
(1984)
The lungs of 46 adult, wild passerine birds belonging to 8 species have been analysed morphometrically, both by light and electron microscope. Volumes were estimated by point counting, surface areas by intersection counting, ...
Morphometrics of the avian lung. 2. The wild mallard (Anas platyrhynchos) and graylag goose (Anser anser).
(1982)
The lungs of 5 wild mallard ducks (Anas platyrhynchos) and 5 feral graylag geese (Anser anser) of mean body weight 1.04 and 3.84 kg, respectively, were fixed in situ by intratracheal infusion of 2.3% glutaraldehyde, pH 7.4 ...
A scanning electron microscopic study of the air and blood capillaries of the lung of the domestic fowl (Gallus domesticus)
(Birkhäuser-Verlag, 1982)
Air and blood capillaries of the lung of the domestic fowl constitute the functional gas exchange units. They anastomose profusely and interlace with each other in 3 dimensions. Air capillaries are not blind-ending tubules ...
Gill structure of a fish from an alkaline lake: effect of short-term exposure to neutral conditions
(Research Press, 1995)
The morphology and morphometry of the gills of Oreochromis alcalicus grahami, a unique ureogenic teleost that lives in the alkaline environment of Lake Magadi, Kenya (pH 10, , temperature 30 – 40 °C) were examined by ...
A morphometric analysis of the lung of a species of bat.
(1982)
The lungs of five adult Epauleted Fruit-bats (Epomophorus wahlbergi) of mean body weight 96 g were analysed morphometrically. The lung volume per unit body weight was 0.043 cm3/g, the surface area of the tissue barrier ...
Fundamental structural aspects and features in the bioengineering of the gas exchangers: comparative perspectives.
(2002)
Over its life, an organism's survival and success are determined by the inventory of vital adaptations that its progenitors have creatively appropriated, devised and harnessed along the evolutionary pathway. Such conserved ...
