1. Healthy Artery
A healthy artery with normal blood flow |
|
|
2. Unhealthy Artery
An unhealthy artery in a person with high blood pressure who also smokes. This artery is hardened and thickened and therefore less able to dilate and constrict, meaning greater force is required to pump the blood through |
|
|
3. Healthy Blood Vessel
Healthy blood vessels are smooth and elastic |
|
|
4.Unhealthy Vessel
In people with high blood pressure, the stretchy elastic fibers in the walls of the blood vessels are replaced with less flexible material |
|
|
5. Healthy Kidney
Kidney of a healthy person |
|
|
6. Unhealthy Kidney
High blood pressure has damaged the arteries and tiny blood vessels where filtration occurs as seen in this kidney |
|
|
7. Healthy Retina
Retina of a healthy person |
|
|
8. Unhealthy Retina
High blood pressure can cause vision problems by bursting the tiny blood vessels supplying the retina |
|

|
|
10. Heart Attack
This person suffered a heart attack. The darkened area was deprived of oxygen during the heart attack, leading to death of the tissue in that area |
|
|
11. Cross Section of Healthy Heart
A healthy heart is able to pump normally |
|
|
12. Cross Section of an Enlarged Heart
Conditions such as high blood pressure and heart attack cause damage to the heart muscle forcing it to work harder. As a result, the heart muscle increases in size, and over time the heart walls thicken, become stretched and grow stiff. Gradually the heart loses its pumping ability. This is known as heart failure |

13. Blood Pressure Classifications
Blood pressure classifications (mm Hg) as outlined by the NHLBI. Normal blood pressure is defined as <120/80 mm Hg. For patients with chronic kidney disease or diabetes, blood pressure goal is <130/80 mm Hg |
