Hormones:

Hormones are chemical messengers in the body. They are secreted by endocrine glands. They travel in the blood to target organs. They reguate many body processes. 

Pancreas - Insulin

Testes - Testosterone

Ovaries - Oestrogen and Progesterone

Nervous System - Via neurones, fast

Hormones - Via blood, slower

Glucose levels too high:

  • Pancreas secretes (releases) insulin
  • Insulin travels in blood to liver
  • Liver takes in more glucose
  • Glucose is stored as glycogen
  • Result: Less glucose in blood

Glucose levels too low:

  • Pancreas stop producing insulin
  • Liver cells break down glycogen into glucose
  • Result: More…
