Varicose Veins

Many people suffer from varicose veins. These are veins in which the
walls of the vessel have become weak and do not have much muscle tone.
Why is this particularly dangerous to blood circulation returning from the
body back to the heart?
You might need to look up information on varicose veins in the library or
on the Internet.
Prepare colored drawings that show what is happening when a person has
varicose veins.
