A | B |
Endocrine System | Secretes hormones that regulate human body |
Hormones | Secreted by glands into the bloodstream |
Hypothalamus | Controls the release of hormones by the pituitary gland |
Pituitary Gland | Controls the activities of other glands |
Growth Hormone (GH) | ontrols the growth of the body by stimulating the elongation of bones |
Thyroid Stimulating Hormone (TSH) | Stimulates the thyroid gland to produce its hormone thyroxin |
Follicle Stimulating Hormone (FSH) | Stimulates the activities of the ovaries and testes |
Thyroid Gland | Secretes thyroxin which contains iodine |
Thyroxin | Regulates the rate of metabolism in the body and is essential for normal physical and mental development |
Goiter | Disease from lack of iodine in the diet |
Parathyroid Gland | Controls calcium metabolism |
Adrenal Gland | Secretes adrenalin |
Adrenal Cortex | Regulate water balance and blood pressure |
Adrenalin | Increases the blood sugar level and accelerates the heart and breathing rate |
Pancreas | Secrete insulin and glucagon |
Insulin | Lowers blood sugar levels |
Diabetes | When tPancreas fails to produce enough insulin |
Testes | Secrete testosterone |
Ovaries | Secrete estrogen |
Negative Feedback | the level of one hormone in the blood inhibits the production of another hormone |
Feedback mechanism | the level of one substance influences the level of another substance |
Dynamic equilibrium | Balance using feedback mechanisms |
Dynamic equilibrium | homeostasis |
Homeostasis | internal stability/ balance |
Testerone | Male sex hormone |
Estrogen | Female sex hormone |
