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. Why is a heart defect a problem for a person who is born with it?
2. What problems does a person have when they have varicose veins?
3. What is the result of a person having anemia?
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. Why is a heart defect a problem for a person who is born with it?
2. Why do the veins become swollen if a person has varicose veins?
3. What happens when a person has low levels of red blood cells?
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. Approximately how many children are born each year with heart defects?
2. How can some types of heart defects be corrected?
3. Explain what makes varicose veins swollen.
