What are arteries?

1. Special equipment that helps a person who is ill or disabled to perform ADLs

2. Difficulty using or understanding words

3. Thickening and hardening of the arterial walls

4. Vessels that carry blood away from the heart

The correct answer is: Vessels that carry blood away from the heart

Arteries are defined as vessels that carry blood away from the heart. This role is crucial in the circulatory system, as arteries transport oxygen-rich blood to various tissues and organs throughout the body. The structure of arteries is designed to withstand the high pressure of blood being pumped from the heart, allowing for efficient delivery of oxygen and nutrients. Understanding this function is vital for recognizing how cardiovascular health impacts overall well-being. The other options do not accurately describe arteries. For instance, the first option pertains to assistive devices for daily activities, which relates to personal care rather than vascular anatomy. The second option describes a language disorder, unrelated to the function of arteries. The third option, thickening and hardening of arterial walls, refers to a condition known as atherosclerosis, which is a health concern involving arteries rather than a definition of what arteries are.
