Verified step by step guidance

Understand the problem: The question is asking about a condition where bacteria and their toxins are spread throughout the body via the circulatory system.

Identify key terms: 'Bacteria', 'toxins', and 'circulatory system' are crucial to understanding the condition being described.

Recall relevant concepts: Septicemia, also known as sepsis, is a serious medical condition where bacteria and their toxins enter the bloodstream, leading to widespread inflammation and potentially severe complications.

Differentiate from other conditions: Leukopenia is a decrease in white blood cells, thrombocytopenia is a low platelet count, and anemia is a deficiency in red blood cells. None of these directly describe the systemic spread of bacteria and toxins.

Conclude with the correct term: The condition described, where bacteria and toxins are carried throughout the body by the circulatory system, is known as septicemia.
