Bacteria are unicellular and they do not have a cirulatory system.
The bacterium that produces methane gas in the gut is called Methanobrevibacter smithii. It is a type of archaea that resides in the human digestive system and plays a role in methane production during the breakdown of food.
The blood in the systemic circulation system is oxygenated. It carries oxygen from the lungs to the rest of the body's tissues and organs.
The SYSTEMIC CIRCULATION transfers oxygenated blood from a central pump (the heart) to all of the body tissues (systemic arterial system) and returns deoxygenated blood with a high carbon dioxide content from the tissues to the central pump (systemic venous system). The PULMONARY CIRCULATION is where oxygen and carbon dioxide exchange between the blood and alveolar air occurs. The PORTAL CIRCULATION normally is only one capillary bed for each branch of a circuit, however, there are a few instances where there are two capillary beds, one after each other, in series. hope this helps^_^
The plural of bacterium is bacteria.
Systematic circulation is the circulation of blood from the heart, to the body and then back to the heart again, while pulmonary circulation is the circulation of blood from the heart, to the lungs and then back to the heart.

Not enough information circulation from where to where? see discuss
