how blood pressure affects blood flow

Healthy arteries are flexible, strong and elastic. Their inner lining is smooth so that blood flows freely, supplying vital organs and tissues with nutrients and oxygen.

Hypertension gradually increases the pressure of blood flowing through your arteries.

Damaged and narrowed arteries. High blood pressure can damage the cells of your arteries’ inner lining. When fats from your diet enter your bloodstream, they can collect in the damaged arteries. Eventually, your artery walls become less elastic, limiting blood flow throughout your body.

Aneurysm. Over time, the constant pressure of blood moving through a weakened artery can cause a section of its wall to enlarge and form a bulge (aneurysm). An aneurysm can potentially rupture and cause life-threatening internal bleeding. Aneurysms can form in any artery throughout your body, but they’re most common in your body’s largest artery (aorta).
