Document Summary

Levels of organization of living things: chemical, cellular, tissue, organ, organ system, organismal. Negative feedback = the counteraction of an effect to return an organism to homeostasis. Steps: stimulus: produces change in variable, change is detected by a receptor (aka sensor ) Body temperature: the hypothalamus responds to a low body temperature by shivering, and a high body temperature by sweating. Blood pressure: the heart, aorta, and internal carotid artery have sensors that can detect changes in bp, when blood pressure is too high, the heart rate slows and blood vessels relax to allow more blood through. Blood sugar: when blood sugar is too high, the pancreas secretes insulin to lower blood sugar, when blood sugar is too low, the pancreas secretes glucagon to raise blood sugar. Erythropoiesis (red blood cell production: when the kidneys detect low blood oxygen levels, the secrete erythropoietin, a hormone that increases the production of red blood cells (erythrocytes)
