The endocrine system consists of all the glands and tissues which secrete hormones and the mechanisms by which the secretion of those hormones is regulated.   The functions of the endocrine system are very diverse and include control of growth, of sexual function, of calcium metabolism and of the uptake of glucose by body cells.

Part 12.2 is to be applied to assess loss of haemopoietic function. The haemopoietic system consists of all the tissues, such as bone marrow and lymph nodes, that produce blood cells.
