The Endocrine System
The endocrine system consists of glands, hormones, and receptors. It is a messenger system that uses hormones released by glands to regulate and communicate with distant organs. Hormones travel through the circulatory system to the correct receptors.
The Immune System
The immune system is a complex network of cells, tissues, organs, and substances that protect the body. Its primary function is to prevent or limit infection and disease.
Hanger, or feeling angry or irritable when hungry, can be caused by hormonal changes and brain cell activation. When blood sugar levels drop, the body releases hormones like adrenaline and cortisol to rebalance it. Adrenaline can make people feel more aggressive or grumpy. Cortisol is a stress hormone that can make people feel overfocused and jumpy. Hunger also activates brain cells called AgRP neurons, which can trigger negative emotions like fear, anxiety, and anger.
