There is a big difference between an artery and a capillary.
Just like arteries and veins, capillaries are also of three types. Let’s see them briefly.
Types of capillaries
- Continuous capillaries: these are the most common type of capillaries. They are found in the skin, finger, skeletal muscles, and gonad.
- Fenestrated capillaries: they are marked by the presence of pores or holes. They can be found in the small intestine, pancreas and kidney glomerulus.
- Sinusoidal capillaries: these capillaries are flattened and can be found in the liver, spleen, bone marrow, and adrenal glands.
Outlined below are some differences between an artery and a capillary.

Four differences between an artery and a capillary
- An artery is a blood vessel that conducts blood from the heart to other parts of the body.
- The capillary does not take blood to or from the heart, instead, it connects the arteries and the veins. Its function is to allow the exchange of oxygen and carbon dioxide between the artery and vein.
- The walls of the arteries are thick. Meanwhile, capillaries have thin walls with a diameter of about 8 microns.
- Unlike the artery, no pulse can be felt in a capillary.
Capillaries are tiny blood vessels, and they function to allow the exchange of substances between the blood and tissue. Arteries are bigger than capillaries.
