Morphological classifications of vertebrate blood capillaries.
BENNETT, H. STANLEY, JOHN H. LUFTANDJAMES C.HAMPTON. Morphological class$kations of vertebrate blood capillaries. Am. J. Physiol. Ig6(2): 381-390. I g5g.Morphological features of blood capillaries from various vertebrate forms and organs are presented. Simple classifications are proposed, based on presence or absence of continuous basement membrane, on the nature of the endothelial cell and on ...
متن کاملStudies on Blood Capillaries
The pathway by which intravenously injected ferritin molecules move from the blood plasma across the capillary wall has been investigated in the muscle of the rat diaphragm. At 2 min after administration, the ferritin molecules are evenly distributed in high concentration in the blood plasma of capillaries and occur within vesicles along the blood front of the endothelium. At the 10-min time po...
متن کاملMorphological castes in a vertebrate.
Morphological specialization for a specific role has, until now, been assumed to be restricted to social invertebrates. Herein we show that complete physical dimorphism has evolved between reproductives and helpers in the eusocial naked mole-rat. Dimorphism is a consequence of the lumbar vertebrae lengthening after the onset of reproduction in females. This is the only known example of morpholo...
متن کاملMechanics of Blood Flow in Capillaries
Blood is a concentrated suspension of red blood cells (RBCs). Motion and deformation of RBCs can be analyzed based on knowledge of their mechanical characteristics. Models for single-file motion of RBCs in capillaries yield predictions of apparent viscosity in good agreement with experimental results for diameters up to about 8 μm. In living microvessels, flow resistance is also strongly influe...
متن کاملA Comparative Study of Morphological Classifications of Apm Galaxies
We investigate the consistency of visual morphological classiications of galaxies by comparing classiications for 831 galaxies from six independent observers. The galaxies were classiied on laser print copy images or on computer screen produced from scans with the Automated Plate Measuring (APM) machine. Classiications are compared using the Revised Hubble numerical type index T. We nd that ind...
