The endocrine system is the group of glands that produce hormones that control the metabolism, growth and development, tissue function, reproduction, sleep, mood, and other things.
Some other glands that the video did not talk about are:
~ Hypothalamus gland : It links the nervous system with the endocrine system.
~Thyroid Gland: Controls and releases energy from food molecules.
~Thymus: It helps immune system fight infections.
~Parathyroid Gland: Releases hormones that regulate calcium levels
Diabetes is connected to the endocrine system. Hormones affect glucose levels and when you have diabetes your body produces too much insulin and causes glucose levels to be low.
Hormones also play a big roll in the Endocrine system. They control the speed of the organs activity, and your mood. Hormones also connect the endocrine system with the nervous system. Lets say you touch your hand to a hot stove, automatically you will move your hand away because of the pain. When this happens hormones signal you to move your hand away.
This diagram shows all of the organs and glands associated with the endocrine system.
Negative feedback controls hormone levels, when there is enough of a hormone the body sends negative feedback to the pituitary gland to stop the body from making that hormone.
Some hormones are only meant for certain cells, these are called target cells. The hormone will only go to that cell, almost like a key to a lock.
The endocrine system is essential for us to grow and live.
