Fig. 4. Representative traces showing the effects of changing intracellular pH on resting tension of afferent (ABA) and efferent (EBA) branchial and celiacomesenteric (CMA) arteries in Hepes and Cortland buffer. Application of 40 mmol l^–1 NH₄Cl produces intracellular alkalosis and its removal produces acidosis. Vertical scale bar = 1 g tension in all traces.
