The central arteriole and venula bifurcate several times and arteriolar and venular branches run mostly in parallel with some crossovers.
Angiotensin, on the other hand, causes vasoconstriction on the systemic arterioles, and acts as a dipsogen for ostriches.
The large number of microcirculation networks connecting each arteriole to a venule also makes the method of discretely modelling individual vessel segments for each microcirculation network computationally prohibitive.
Amyloid angiopathy is associated with deposition of beta-amyloid in the vessel wall affecting the leptomeningeal and cortical arterioles and capillaries.
Low perfusion pressure in the afferent arteriole triggers the juxtaglomerular apparatus to release rennin, which in turn leads to an increase in aldosterone and thereby causes sodium absorption and retention.
Lumina of all the vessels, including muscular arterioles were wide open.
E-selectin is weakly expressed on some arterioles and venules.
No transient intermissions of flow in arterioles or absence of flow were found in any dog, even with the stepped flow decrease to 10 ml/kg/min.
