Disease of the Circulatory System
Hypertension
•
Blood flows through the blood
vessels with a force greater than normal i.e. with a blood pressure
reading of 140/90
•
When
the blood pushes harder against the walls of your arteries, your blood
pressure goes up
Prevention
•
Quit
smoking
•
Exercise
regularly
•
Reduce
amount of sodium

A
heart attack happens when the flow of oxygen-rich blood to a section of heart
muscle suddenly becomes blocked and the heart can’t get oxygen.
•
If
blood flow isn’t restored quickly, the section of heart muscle begins to die.
•
Coronary
Heart disease
