- blood vessels transport blood throughout the body. Humans have three types of blood vessels; artery, veins and capillaries.
Arteries
Arteries are blood vessels that takes oxygenated blood away from the heart. It delivers oxygen and nutrients throughout your body. It appears red when viewed through the skin depends on your skin colour. :max_bytes(150000):strip_icc()/GettyImages-140891898-5add87608023b90036831a01.jpg)
Veins
Veins are blood vessels that takes de-oxygenated blood back to the heart that received fresh oxygen. It is less more muscular than arteries and has thinner walls. It appears blue when they are close to the skin because of the diversion of light through the skin.
Capillaries
Capillaries are blood vessels that contains both oxygenated and de-oxygenated blood. It's the smallest blood vessels in the body and it's one-cell thick. It exchange oxygen, nutrients and wastes in your blood.
