1. AIM: How do circulatory system diseases affect bodily homeostasis? DO NOW 1.Why is it so important to try to keep the heart and circulatory system healthy? 2.What problems can people have? 3.What can you do to maintain good cardiovascular health?

2. Circulatory System Diseases Also called Cardiovascular Diseases https://www.brainpop.com/health/nutrition/f ats/ https://www.brainpop.com/health/nutrition/f ats/ “One should eat to live, not live to eat.” –Cicero, Roman statesman

3. High Blood Pressure (Hypertension) Most common form of cardiovascular disease Causes: Stress, diet, heredity, cigarette smoking, aging Effects: – Artery lining gets damaged – Heart muscle gets weakened

16. Anemia Causes: multiple  include vitamin & iron deficiencies Effects: – The blood does not have enough hemoglobin or red blood cells – body cells do not receive enough oxygen Symptoms: fatigue, weakness, shortness of breath, pale skin, dizziness

17. Visual

18. Sickle-Cell Anemia Cause: genetics (inherited) Effects: – hemoglobin protein is abnormal & RBC’s have a sickle-shape – RBC’s can get stuck in blood vessels, due to abnormal shape – tissues & organs are deprived of oxygen-rich blood  organ damage

21. Group-Work In pairs, work on handout (regents question)

22. Individual Work On looseleaf, answer the following question: Q: Is there anyone in your family, or outside of your family that has a circulatory system disease? If so, who? Which disease? In addition, explain what this person has experienced. Note: If you do not know anyone, answer the lesson’s AIM.
