Directions: ANSWER USING COMPLETE SENTENCES! Use the information you have been given to answer questions about: Anemia, Varicose Veins, and Heart Defects

Level#1: Anemia, varicose veins, and heart defects are examples of circulatory system disorders. Anemia occurs when there are low levels of red blood cells in the body and the body's organs and tissues do not get enough oxygen. Varicose veins occur when a vein becomes swollen and the valves do not close properly and start to leak. A heart defect is when a person is born with a heart that is not developed properly and does not work well as a result.

1. What are the signs that a person may have anemia?





2. What are the signs that a person may have varicose veins?





3. What is a heart defect?







Level#2: Anemia, varicose veins, and heart defects are examples of circulatory system disorders. Anemia occurs when there are low levels of red blood cells in the body. Without the correct amount of red blood cells, the body's organs and tissues do not get enough oxygen and cannot work properly. Varicose veins occur when a vein becomes swollen and the valves do not close properly and start to leak. A heart defect is when a person is born with a heart that is not developed properly and does not work well as a result. Some types of heart defects can be corrected by surgery.

1. What is anemia and how does it affect the body?

3. What is a heart defect?








Level#3: Anemia, varicose veins, and heart defects are examples of circulatory system disorders. Anemia occurs when there are low levels of red blood cells in the body. Without the appropriate number of red blood cells, the body's organs and tissues do not get enough oxygen and cannot work properly. Varicose veins occur when a vein becomes swollen. This  happens because the valves that move blood to the heart do not close properly and start to leak. A heart defect is an abnormality of the heart's structure or function. Heart defects are disorders that people are born with. Approximately 30,000 to 40,000 (or 1 in 1,000) children are born each year with a heart defect. Some types of heart defects can be corrected by surgery.

1. Explain what anemia is and how it can cause problems in the body.
