Is immunology the study of hormones and endocrine organs?

No, immunology is not the study of hormones and endocrine organs. Immunology is the study of the immune system, which is a complex network of cells, tissues, and organs that work together to defend the body against harmful pathogens and infections. Endocrinology, on the other hand, is the study of hormones and the endocrine glands that produce and secrete them into the bloodstream.
