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 ...
The morphology of the lung of the black mamba Dendroaspis polylepis (Reptilia: Ophidia: Elapidae). A scanning and transmission electron microscopic study
(1989)
The lung of a snake, the black mamba (Dendroaspis polylepis), has been investigated by scanning and transmission electron microscopy. This species has only one lung, the right, which is long and occupies most of the ...
The morphology of the lung of the black mamba Dendroaspis polylepis (Reptilia: Ophidia: Elapidae). A scanning and transmission electron microscopic study
(1989)
The black mamba (Dendroaspis polylepis) belongs to the family Elapidae that also
includes the cobras, kraits and coral snakes. Generally, these snakes are extremely
venomous and occur in the warmer parts of the world ...
The morphology of the respiratory organs of the African air‐breathing catfish (Clarias mossambicus): A light, electron and scanning microscopic study, with morphometric observations
(University of Nairobi, 2011-03)
The morphology of the gas exchange organs of the African air-breathing catfish (Clarias mossambicus) (Peters) have been examined grossly, and by light, electron and scanning microscopes. The respiratory organs in Clarias ...
Surface specialization of the capillary endothelium in the pecten oculi of the chicken, and their overt roles in pectineal haemodynamics and nutrient transfer to the inner neural retina
(Univesity of Nairobi, 1997)
The structure of the capillary endothelium in the pecten oculi of the domestic fowl was investigated by scanning and transmission electron microscopy. Scanning electron microscopy results demonstrated the existence of a ...
Histological Reactions to Bites of Amblyomma variagatum and Rhipicephalus appendiculatus (Acari: Ixodidae) Fed Simultaneously on Naive or Sensitized Rabbits
(Entomological Society of America, 1990)
Histopathological studies on attachment sites of nymphs, 48 h after attachment on three groups of rabbits, have revealed differences that were related to the rabbits'previous tick experience. Feeding lesions caused by ...
A stereological comparison of villous and microvillous surfaces in small intestines of frugivorous and entomophagous bats: species, inter-individual and craniocaudal differences
(1997)
The extents of functional surfaces (villi, microvilli) have
been estimated at different longitudinal sites, and in the
entire small intestine, for three species of bats belonging to
two feeding groups: insect- and ...
Genetic structure of Lake Magadi tilapia populations
(Wiley, 2000)
The control region of the mitochondrial DNA haplotype frequencies were significantly different among the two separate lagoon populations of Oreochromis alcalicus grahami in Lake Magadi and of O. a. alcalicus from lake ...
Comparative in vitro study of interactions between particles and respiratory surface macrophages, erythrocytes, and epithelial cells of the chicken and the rat
(2008)
In mammals, surface macrophages (SMs) play a foremost role in protecting the respiratory system by engulfing and
destroying inhaled pathogens and harmful particulates. However, in birds, the direct defense role(s) that ...
Scanning electron microscope study of the spatial organization of the air and blood conducting components of the avian lung (Gallus gallus variant domesticus)
(University of Nairobi, 1988)
The lungs of the domestic fowl were prepared for scanning electron microscopy after vascular and airway latex rubber casting to demonstrate the spatial organization of the various structural components that are involved ...
