Endocrine System Alex Wiemann

Function of the Endocrine System The endocrine system synthesizes hormones and releases them into the body. Hormones act as chemical messengers that help regulate and maintain various body functions.

Homeostasis is the regulation of the internal environment of the body. The endocrine system maintains homeostasis. If hormones levels were to become unbalanced, it would have detrimental effects on the body.

Negative Feedback Mechanisms Negative feedback is when the glands within the endocrine system that stimulate the release of a hormone from another gland are eventually shut off so that too much hormone is not produced. One example of a negative feedback mechanism is when the hypothalamus secretes TRH. This causes the pituitary to release TSH, which makes the thyroid gland secrete thyroid hormone. When the body has enough thyroid hormone in the blood, the hormone causes a decrease in secretion of TRH and TSH by the hypothalamus and pituitary.

Endocrine Glands

Glands Gland Hormone Secreted Action of Hormone Pituitary ACTH Causes adrenal glands to produce cortisol Thyroid T 3 Controls metabolism Parathyroid PTH Increases the concentration of calcium in the blood Thymus Humoral factor Develops lymphoid system Adrenal Glucocorticoids Controls blood sugar Pancreas Insulin Maintains glucose levels Ovaries Estrogen Develops female sexual traits Testis Testosterone Develops male sexual traits

Diabetes Type II Description The body cannot produce enough insulin The body produces insulin, but cannot use it Signs and symptoms Exhaustion, increased thirst/ urination, blurred vision, weight loss, constant hunger, slow healing of wounds Prevalence Signs begin in children and teens Signs begin showing in adults Treatment Insulin injections, blood sugar checks, exercise , dietary plans, no cure Cured with exercise, dietary plans, weight loss, medications may help
