Problems with the return process can lead to stress on the heart and a range of circulatory and blood flow issues. Basic Anatomy of the Heart. The heart is the core of the circulatory system, and it is responsible for pumping and processing the blood for the entire body.
Vibrio cholerae strains. Two serogroups of V. cholerae â O1 and O139 â cause outbreaks. V. cholerae O1 causes the majority of outbreaks, while O139 â first identified in Bangladesh in 1992 â is confined to South-East Asia. Non-O1 and non-O139 V. cholerae can cause mild diarrhoea but do not generate epidemics.
