Understanding the Medical Terminology
The query from Quizlet likely refers to the broad, all-encompassing term for the condition. The overall medical term for hardening of the arteries is arteriosclerosis. This condition involves the stiffening and thickening of the arterial walls, which can lead to restricted blood flow. It is important to know that arteriosclerosis is a general term, and there are several specific types, each with its own underlying cause.
The Critical Distinction: Arteriosclerosis vs. Atherosclerosis
Many students find these terms confusing, but it’s a key distinction in medical terminology. The easiest way to remember is that atherosclerosis is a specific type of arteriosclerosis, but not all arteriosclerosis is atherosclerosis.
- Arteriosclerosis: This is the broad term for any hardening of the arteries, regardless of the cause. This can happen due to age, high blood pressure, or other factors that cause the artery walls to lose elasticity.
- Atherosclerosis: This is the most common form of arteriosclerosis and specifically refers to the buildup of plaque within the artery walls. Plaque is a sticky substance composed of cholesterol, fat, cellular waste, and other materials. As this plaque accumulates, it hardens and narrows the arteries, restricting blood flow and increasing the risk of clots.
Other Types of Arteriosclerosis
To provide a more comprehensive answer beyond what is typically found on Quizlet, it's useful to know that there are other forms of the condition:
- Arteriolosclerosis: Affects the small arteries and arterioles, often associated with high blood pressure and diabetes.
- Medial arterial calcification: Involves calcium buildup in the middle layer of the artery walls, common in those with kidney failure.
What Causes Hardening of the Arteries?
Arteriosclerosis is a slow, progressive disease that often develops over many years. The exact cause is not always clear, but a gradual buildup of plaque or thickening due to inflammation is a primary driver, particularly in the case of atherosclerosis. Several risk factors are known to increase the likelihood of developing the condition:
- High cholesterol and triglyceride levels, especially elevated LDL (bad) cholesterol.
- High blood pressure (hypertension), which can damage artery walls.
- Smoking or any form of tobacco use, which can damage blood vessels.
- Diabetes, which is associated with higher cholesterol and blood pressure.
- Obesity and a sedentary lifestyle, which increase the risk of other health issues that contribute to arterial hardening.
- Advanced age, as arteries naturally stiffen over time.
- Family history of heart disease.
Symptoms to Watch For
In its early stages, arteriosclerosis often presents with no symptoms. These typically only appear when an artery has become significantly narrowed or blocked. The location of the affected arteries determines the symptoms that manifest:
- Coronary Arteries (supplying the heart):
- Chest pain or pressure (angina)
- Shortness of breath
- Heart palpitations
- Carotid Arteries (supplying the brain):
- Sudden numbness or weakness on one side of the body
- Trouble speaking or slurred speech
- Temporary vision loss in one eye
- Peripheral Arteries (in the arms and legs):
- Leg pain, especially when walking (claudication)
- Numbness or weakness in the limbs
- Renal Arteries (supplying the kidneys):
- High blood pressure
- Kidney failure over time
Diagnosis and Treatment Options
A doctor will start with a physical exam, which may include listening for a whooshing sound (a bruit) over an artery with a stethoscope, indicating poor blood flow. Further diagnostic tests may include:
- Ankle-brachial index: Compares blood pressure in your ankle and arm to check for reduced blood flow in the limbs.
- Blood tests: To check for high cholesterol and blood sugar levels.
- Cardiac imaging: X-rays, CT scans, and MRIs can reveal blockages or calcification.
- Stress tests: Show how the heart performs under physical strain.
Treatment depends on the severity and location of the condition and typically involves a combination of strategies:
- Lifestyle changes: Eating a heart-healthy diet, regular exercise, and quitting smoking.
- Medication: To lower cholesterol, blood pressure, or prevent blood clots.
- Surgical intervention: In severe cases, procedures like angioplasty or bypass surgery may be necessary to open or bypass blocked arteries.
Comparison of Arteriosclerosis and Atherosclerosis
| Feature | Arteriosclerosis | Atherosclerosis |
|---|---|---|
| Definition | General term for any hardening of arteries | A specific type of arteriosclerosis caused by plaque buildup |
| Cause | Can be caused by aging, hypertension, or other factors | Caused by plaque accumulation (fat, cholesterol) inside artery walls |
| Scope | Broad, affects various blood vessel types | Specific to large and medium-sized arteries |
| Consequences | Reduced blood flow, risk of heart disease, stroke | Heart attack, stroke, aneurysm, depending on location |
Prevention Strategies
Prevention is key to managing arteriosclerosis. Most risk factors can be controlled with simple lifestyle changes. A heart-healthy lifestyle, initiated early, is the best defense against this progressive disease. Here are some effective strategies:
- Maintain a heart-healthy diet: Focus on fruits, vegetables, whole grains, and lean proteins while limiting saturated fats, trans fats, and excess sodium.
- Exercise regularly: Aim for at least 30 minutes of moderate-intensity exercise, such as brisk walking, most days of the week.
- Quit smoking: This is the single most important change you can make to reduce your risk.
- Control blood pressure and cholesterol: Follow your doctor's recommendations for managing these levels, which may include medication.
- Manage stress: High stress levels can impact blood pressure and heart health.
- Limit alcohol intake: Excessive alcohol consumption is a risk factor.

Conclusion: The Final Answer and a Lifelong Plan
In summary, the term you're looking for to complete your Quizlet question is most likely arteriosclerosis, the general term for hardening of the arteries. However, the more common and specific form is atherosclerosis, which involves plaque buildup. While the condition can lead to serious complications like heart attack and stroke, it is largely preventable through lifestyle adjustments. By managing risk factors like blood pressure, cholesterol, and diet, and maintaining an active, smoke-free lifestyle, you can significantly reduce your risk and keep your arteries healthy for years to come.
