[Skeletal muscle blood bed in growing rats]

Morphometric study of vascular bifurcations and capillaries in biceps femoris artery basin was performed in 2-week old, 1-month old, and adult Wistar rats. Proceeding from the results, the blood tree was digitally reconstructed, and the main haemodynamic parameters in digital simulation were evaluated in this vascular bed: the blood flow velocity, wall shear stress, drop of perfusion pressure, and resistance. The comparison with a similar study of cerebral vascular bed revealed peculiarities of the vascular bed formation and intraorgan haemodynamics in these organs.
