INTRODUCTION TO CARDIOVASCULAR DISEASES:
- HOW HEART WORKS?
Your lungs receive blood from your heart first. Here, oxygen from the air that you’ve breathed in is taken up by the blood.
The blood then returns to your heart while carrying oxygen.
The blood is given another push by the heart.
Once again, everything starts when the blood returns to the heart.

When a portion of the heart muscle is not getting enough blood, a heart attack occurs. The heart may need more oxygen than is available, there is a blockage, or an artery around the heart has torn.
