Adrenal Gland Structure
Medulla and Cortex. Cortex consists of zona glomerulosa, zona fasciculata and zona reticularis
Medulla secretes
adrenaline, epinephrine and norepinephrine
Zona Glomerulosa secretes
Mineralcorticoids
Zona Fasciculata secretes
Glucocoritcoids: cortisol and cortisone
Zona Reticulatis secretes

Lymphoid organs include:
Spleen, Thymus, Tonsils, Peyer’s patches of the intestine and the appendix.

The whole of the body, excluding the right arm, right side of the head and right thorax, which are collected by the right lymphatic duct.
Three sets of tonsils are:
Palatine, lingual and pharyngeal (adenoids)
Lymphatic ducts empty into:
