All About Veins

What are Veins?

What are veins? Everyone has them, but do we really know what purpose they serve? Veins are elastic blood vessels that transport blood from various regions of the body to the heart. Veins are part of the cardiovascular system, which circulates blood throughout the body to provide nutrients to the cells of the body. Each vein is made up of three layers: membranous tissue on the inside, thin bands of smooth muscle in the middle, and connective tissue on the outside. Unlike arteries, veins rely on muscle contractions to return blood to the heart. But together veins and arteries form an important network to transport blood throughout the body. Read our blog to learn all about veins, problems that can accompany them and effective treatment solutions that are available!

Types of Veins

There are four different types of veins: pulmonary, systemic, superficial, and deep veins.

Pulmonary veins – Large blood vessels that take oxygenated blood from the lungs and deliver it to the left atrium of the heart.

Systemic veins – The circuit through the rest of the body that provides oxygenated blood to the right atrium of the heart.

Superficial veins – Located close to the skin and are not accompanied by arteries.

Deep veins – Located deep within muscle tissue and are usually located beside a corresponding artery.

Vein Problems

Vein problems occur when veins have trouble sending blood from the limbs to the heart. Inadequate flow of blood through the veins leads to a blockage. Blockages occur due to blood clots that develop in superficial veins or deep veins (usually in the legs and arms). Vein injuries or disorders activate blood cells known as platelets and thrombocytes which lead to blood clots.

Vein problems can also occur due to varicose veins. Varicose veins are swollen and twisted veins that show up under the skin. They are a result of damaged vein valves that allow blood to pool in the veins. Damaged valves cause the veins in the body to swell which can lead to varicose veins. Varicose veins usually appear in pregnant women, people with vein injuries and individuals with a genetic family history of varicose veins. The good news is that varicose veins can be prevented and also easily treated!

Now that you know all about veins and the problems that can accompany them, you can take preventative measures to decrease your risk of developing varicose or spider veins in the future!
