  1. Endocrine System Kara Robbins

  2. System of glands, each of which secretes different types of hormones directly into the bloodstream to maintain homeostasis Function

  3. Relation to ES - Endocrine System produces hormones that maintain homeostasis What is it? • Internal balance • Tendency toward a relatively stable equilibrium between interdependent elements Homeostasis

  4. Self-regulating responses to changes experienced by an organism or system • feed some of the output of these changes back into the system to trigger counter-responses which result in restoring the system to its previous undisturbed state, or mitigating the effects of the initial change Sweat Gland • Negative feedback mechanism • Releases sweat to help cool body and maintain homeostasis Negative Feedback Mechanism

  5. Insulin Stimulates glucose and fatty acid uptake into adipose cells, causing triglyceride synthesis When present rapidly stimulates glucose transport Needed to convert starch, sugars, and other food into daily energy Hormones - Produced by endocrine cells and travel through blood to reach all parts of the body Cell Signaling Mechanism

  6. Body does not produce insulin • Symptoms: • Increased thirst and frequent urination • Extreme hunger • Fatigue • Blurred vision • Usually diagnosed in children and young adults • Only 5% of people with diabetes have this form • Treatment: • Taking insulin • Exercising regularly • Eating healthy foods • Monitoring blood sugar Type I Diabetes

  7. Body does not produce enough insulin or cells ignore the insulin • Symptoms: • Increased thirst and frequent urination • Increase hunger • Weight loss • Fatigue • Blurred vision • Slow-healing sores or frequent infections • Areas of darkened skin • Occurs in million of Americans • More common in Native Americans, Latinos, African Americans, and Asian Americans • Treatment: • Blood sugar monitoring • Healthy eating • Exercising regularly • Diabetes medication or insulin therapy Type II Diabetes

  8. Occurs when body is exposed to high levels of hormone cortisol for a long time • Symptoms: • Weight gain • Pink or purple stretch marks • Thinning, fragile skin • Slow healing cuts • Acne • 2-4 cases per million people per year • Treatment: • Reducing corticosteroid use • Surgery • Radiation therapy • Medications Cushing’s Syndrome
