Which blood vessel carries blood away from the heart?

Vein
Capillary
Artery
Sinus

The correct answer is: Artery

The vessel that carries blood away from the heart is the artery. Arteries are muscular and elastic blood vessels that transport oxygen-rich blood from the heart to various tissues and organs throughout the body. The main artery originating from the heart is the aorta, which branches into smaller arteries that further distribute the blood. In contrast, veins are responsible for carrying deoxygenated blood back to the heart, capillaries are tiny vessels where the exchange of gases, nutrients, and waste occurs between blood and tissues, and sinuses are large spaces in the body's tissues or organs that allow for the collection of blood. Thus, arteries play a crucial role in the circulatory system by ensuring that oxygenated blood reaches where it is needed, making them essential for maintaining bodily functions.
