The Endocrine System[edit | edit source]
As we read before, the human body is made of many, many cells. To make all these cells work together, the body sends signals through the blood called hormones that tell the cells in the body what to do. The Endocrine System is the organ system made of the organs that make hormones.
Some of the organs in the endocrine system are:
- Pineal gland
- Pituitary gland
- Thyroid gland
