What term refers to a substance that affects the cellular components of blood or its function?

Explanation:
The idea is substances that disrupt the blood-forming system or the blood cells themselves. A hematopoietic toxin is a substance that specifically interferes with hematopoiesis in the bone marrow or damages circulating blood cells, leading to problems in blood cell numbers and function. This makes hematopoietic toxin the best term for effects on the cellular components of blood. Neurotoxins affect the nervous system; nephrotoxins target the kidneys; hepatotoxins damage the liver, which is why they describe different targets rather than the blood-forming system.
