What Is an Artery?
An artery is a blood vessel that carries oxygen-rich blood away from the heart to the body’s organs and tissues. Healthy arteries have strong, flexible walls that allow blood to flow efficiently. Exceptions include the pulmonary arteries, which carry oxygen-poor blood from the heart to the lungs for oxygenation.
Arteries are essential for delivering oxygen and nutrients needed to keep the body’s tissues functioning properly.
Why Arteries Matter
Healthy arteries support normal circulation and organ function. Damage or narrowing of the arteries can reduce blood flow and increase the risk of heart attack, stroke, peripheral artery disease, and other serious cardiovascular conditions.

How Home Care Can Help
Home care professionals support cardiovascular health by encouraging medication adherence, promoting heart-healthy nutrition, monitoring blood pressure, assisting with safe physical activity, encouraging smoking cessation, and observing for signs of reduced circulation.
Home Care Tip
Healthy lifestyle habits, including regular exercise, not smoking, maintaining healthy blood pressure, and controlling cholesterol, help protect your arteries throughout life.
Frequently Asked Questions About Arteries
What is the difference between an artery and a vein?
Arteries carry blood away from the heart, while veins return blood back to the heart. Most arteries carry oxygen-rich blood, while most veins carry oxygen-poor blood.
Can arteries become blocked?
Yes. Fatty deposits called plaque can build up inside arteries, reducing blood flow and increasing the risk of heart attack or stroke.
Can home care help people with arterial disease?
Yes. Home care professionals support medication management, healthy lifestyle changes, symptom monitoring, and chronic disease management to promote cardiovascular health.
When to Seek Medical Care
Seek immediate medical attention if you experience sudden chest pain, severe leg pain with loss of circulation, stroke symptoms, or other signs of reduced blood flow to vital organs.
