The difference between Arteries, Veins, and Capillaries is arteries carry oxygenated blood away from your heart, veins carry deoxygenated blood toward the heart and capillaries connect the arteries to the veins. The Circulatory System of the body consists of Arteries, Veins, and Capillaries. Each plays a vital role in carrying blood throughout your body.

Difference Between Arteries Veins and Capillaries

The human body possesses roughly 60,000 miles of blood vessels. They are broadly classified into Arteries, Veins, and Capillaries. All three vessels deliver oxygen to vital tissues and organs and release waste.

  • Arteries have thick walls and a muscular layer that keeps the blood moving.
  • Veins are often located close to your skin.
  • Capillaries are a minor type of blood vessel.

To Differentiate Between Arteries, Veins, and Capillaries, analyze the table below.:

Arteries Veins Capillaries
Have very thick walls Has a thin layer of muscle tissue inside Have a very thin wall
Located deep in the muscle Carry blood toward your heart Carry both oxygenated and deoxygenated blood
Has a thick layer of muscle tissue inside Have thin walls Don’t have valves
Carry blood from the heart to the organs Carry deoxygenated blood Are located inside all tissues
Have no valves except for the pulmonary artery Are located closer to the surface of your body Carry blood between veins and arteries
Carry oxygenated blood (except for the pulmonary artery) Contains valves to keep blood flowing Don’t have muscle tissue
They are the largest type of blood vessel in your body The capillary wall is made of endothelial cells and allows oxygen, nutrients, and waste to pass to and from tissue cells
