Studies 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 کاملStudies on the Permeability of Lymphatic Capillaries
The passageway for interstitial fluids and large molecules across the connective tissue lymph interface has been investigated in dermal lymphatic capillaries in the ears of guinea pigs. Numerous endothelial cells overlap extensively at their margins and lack adhesion devices at many points. The observations suggest that these sites are free to move as a result of slight pressure changes. Immedi...
متن کاملMorphometric Data on the Endothelium of Blood Capillaries
Local differentiations within the endothelium of both muscular (diaphragm, myocardium) and visceral (pancreas, jejunal villi) capillaries have been studied in rats on sectioned and freeze-cleaved preparations. Four distinct parts have been recognized in the endothelial cells of all these vessels on the basis of subcellular components present in each part and on the basis of variations in the lo...
متن کاملMorphological 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 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...
