blood vessels
Blood vessels are the pathways through which blood flows throughout the body. There are three main types: arteries, veins, and capillaries. Arteries carry oxygen-rich blood away from the heart to supply organs and tissues. Veins return oxygen-poor blood back to the heart. Capillaries are tiny vessels that connect arteries and veins, allowing for the exchange of oxygen, nutrients, and waste between blood and cells. Together, these vessels form the circulatory system, which is essential for transporting vital substances and maintaining overall health.

Blood vessels are the networks of tubes in the body that transport blood. They include arteries, which carry oxygen-rich blood away from the heart to the body; veins, which return oxygen-poor blood back to the heart; and capillaries, the tiny vessels where the exchange of oxygen, nutrients, and waste occurs between blood and cells. Together, they form a vital circulatory system, ensuring that every part of the body receives the necessary nutrients and oxygen while removing waste products. A healthy blood vessel system is essential for overall health and well-being.
