Dear Angie,
Someone told you some fiction

And it does rain during some parades......
This fiction that the thymus is unimportant is the very reason that chronic disease is so rife in the population - in all species.
There are a few exceptions. Cows bred for meat are not necessarily vaccinated, and as adults they have a really good size thymus (I sent a picture recently of a slide of one).
I'm not sure either how you got the endocrine system muddled with the blood making system.
The endocrine system is the hormone system, a system of *glands* that produce hormones. Examples are thyroid (not thymus) gland, pituitary gland, adrenal glands, etc.
Hormones are chemicals produced in the body which tell some distant site what to do, (ie they do not act where they are produced.)
As for blood cells, they are ALL produced in the bone marrow, but many of them need to be further developed and matured in order to take on specific functions, and that takes place in the thymus. In fact the white blood cells that are matured in the thymus are called T-cells, where T is for Thymus.
B-cells are the ones matured only after being developed in Bone marrow (where B is for Bone marrow).
Neither bone marrow nor thymus is part of the endocrine system.
Pax - rainbow?
Namaste,
Irene
