| Endocine system | Consists of ductless glands that work in conjuction with nervous system to regulate the entire body |
| Hormones | Chemicals produced in ductless (endocrine) glands that are transported through the blood to a target cell,tissue, or organ |
| Tropic hormones | Hormones that stimulate other glands to release thier hormones |
| Pheromones | Carry messages between different individuals |
| Posterior pituitary | Stores and releases hormones from hypothalmus |
| Oxytocin | Stimulates concentration of uterus and mammary glands during labor |
| Antidiuretic hormone | Stimulates the collecting tubule in nephron of the kidney |
| Parathyroid gland | Releases parathormone that raises blood calcium levels by removing calcium from bones |
| Hypothalmus | Bridge between endocrine and nervous system that releases oxytocin and antidiuretic hormone into the posterior pituitary |
| Anterior pituitary | Stimulates bome growth, overies and testes, thyroid, adrenal cortex, and gonads |
| Thyroid gland | Releases thyroxin and releases calcitonin |
| Adrenal cortex | Releases corticosteriods that raise blood sugar levels and responds to stress |
| Adrenal Medulla | Releases epinephrine and raises blood sugar levels by increasing breakdown of glycogen in liver |
| Pancreas | Functions as an endocrine gland by releasing hormones and as an exocrine in digestion |
| Insulin | (secreted by beta cells of the islets of langerhans) to lower blood glucose levels |
| Ovaries | (secreted by beta cells of the islets of langerhans) to lower blood glucose levels |
| Estrogen | Stimulates uterine lining , promotes development and maintenance of primary and secondary sexual characteristics in females |
| Proesterone | Promotes growth of uterine lining |
| Negative feedback | Maintains homeostasis |
| Positive feedback | Amplifies an already existing response and brings a process to an end |
| Thymus Gland | An endocrine gland that is essential to the development of a normal immune system and stimulates T- Lymphocytes |
| Pineal Gland | An endocrine gland that is located in the brain and secretes hormone melatonin |
| Testes | An endocrine gland that produces testosterone |
| Testosterone | Supports sperm production and secondary sexual characteristics |
