“…This is particularly pronounced in crocodilians, where the left aorta emanates from the right ventricle and hence carries systemic venous blood whenever systemic arterial pressures are lower than pulmonary pressures in a R-L shunt (Jones & Shelton, 1993). This has led to the idea that the R-L shunted CO 2 -rich blood could stimulate gastric acid secretion during digestion (Jones & Shelton, 1993;Farmer et al, 2008;Gardner, Sterba-Boatwright, & Jones, 2011). Farmer et al (2008 provided evidence that alligators with ligated left aortic arches had slower digestion.…”

“…In addition to the lack of effect of LV on growth rate, there was no influence on conversion efficiency (GCE) or the metabolic response to feeding (SDA). A number of studies on crocodilians have proposed that increased R-L shunt during digestion facilitates gastric acid secretion by supplying CO 2 -rich blood to the stomach (Farmer et al, 2008;Gardner et al, 2011;Jones, 1991), andFarmer et al (Farmer et al, 2008) showed that gastric digestion was delayed when the capacity to R-L shunt was abolished in alligators. Crotalus also exhibit considerable gastric acid secretion upon ingestion of meals (Andrade et al, 2004) and the resulting alkalinisation of the blood is similar to that of alligators (Arvedsen et al, 2005; Busk et al, 2000).…”

“…As described above, it has been proposed that increased R-L shunt serves to provide CO 2 and rich blood to the parietal cells and thus plays an important role in promoting gastric acid secretion during digestion (Jones and Shelton 1993 ;Farmer et al 2008 ;Gardner et al 2011 ) .…”
