Cardiovascular Disease

Damage to the endothelium.

White Blood Cells and lipids form fatty streaks.

Connective tissue forms atheroma.

Partially blocks artery.

Restricts blood flow.

BP increases

Balloon like swelling.

Blood travels through weakened artery pushes inner layers through outer elastic layer.

May burst and cause haemorrhage.

Atheroma plaque can rupture endothelium.

This damages the artery and creates a rough surface.

Platelets form a blood clot.

Blockage of the artery there or further down the artery.

Blood supplied by coronary arteries.

Blood contains oxygen for respiration.

If blocked - no oxygen supplied to heart muscle.

Causes heart attack.

Symptoms - pain, shortness of breath, sweating.
