Bacteria are unicellular and they do not have a cirulatory system.
Respiration need transportation of respiratory gases. This is done by circulation system
circulatory system ^That's wrong.... It is the systemic circulation
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^_^
A bacterium that needs oxygen is called an aerobic bacterium
Bacterium
fishes do have parallel circulation
A contiguous living system, such as a animal, plant, and bacterium.
Pulmonary circulation Pulmonary circulation pulmonary circulation pulmonary circulation

Hemoglobin molecules function as the carrier in the human blood circulation system.
Blood circulation takes oxygen to your system---(circulation)
