What are the vessels that carry blood away from the heart known as?

The vessels that carry blood away from the heart are known as arteries. This is a fundamental aspect of the cardiovascular system. Arteries transport oxygen-rich blood from the heart to the various tissues and organs of the body under high pressure. They have thick, muscular walls that allow them to withstand the high pressure of the blood being pumped from the heart.

The role of arteries is crucial in ensuring that all bodily tissues receive adequate oxygen and nutrients necessary for their function. Understanding the anatomy of the circulatory system is essential for fitness professionals as it relates to how exercise impacts cardiovascular health and overall performance. By recognizing how blood flow is regulated and dispersed throughout the body, trainers can better tailor fitness programs to meet their clients' needs.
