BACK TO ENDOCRINE SYSTEM ANATOMY & PHYSIOLOGY


The liver produces some very important hormones:


Liver
Hormone Regulation and Production Action
Leptin Leptin is produced when the body has had adequate to eat. Sends a signal to the appetite centre of the Hypothalamus indicating satiety. Leptin also seems to be a significant regulator of reproductive function, as animals with low body mass, and thus low leptin levels fail to cycle.
Resistin - Participates in the immune response. It may have some role in obesity and Type II Diabetes mellitus.
