Module 7: Figure metabolic energy network
Metabolic homoeostasis depends upon interactions between cell types that either carry out energy metabolism or provide the hormones responsible for regulation.
Energy derived from food intake enters the plasma from the intestine and is then distributed to cells involved in energy consumption, while any excess is dealt with by cells that function in energy storage. The brain plays a critical role in relaying information to endocrine cells that release the hormones that function in regulating this energy network. The neural and endocrine control of food intake and body weight is described in Module 7: Figure control of food intake.
