The difference between arteries and veins is their function in the circulatory system. These vessels are located all around the body, constantly pumping blood into our systems. These methods of transportation have significant physiology in the circulatory system. All vessels deem to be essential to all organs and tissues due to the necessity of oxygen.

Arteries are the largest vessels in the body composed of thick walls located in the surroundings of muscle. The arteries are responsible for carrying oxygenated blood from the heart to the body and organs. Arterial pulses can be felt throughout the body, being essential in times of crisis. The common pulses that most feel upon touch are from the carotid artery, to the brachial, radial, iliac, femoral, etc. Many medical personnel rely on these pulses to detect changes in circulation in the host.

Capillaries are the smallest vessels used to carry blood from the arteries into the veins which can carry both oxygenated and deoxygenated blood.These vessels are located all over the tissues of the body.

Veins are anatomically different from arteries in size and physiologically different. Veins are composed of very thin walls located close to the skin–hence why blood is drawn from veins due to the fact that they are visible and in close proximity to the skin. The main function of the veins is to carry deoxygenated blood back into the heart to become oxygen-rich once again. The pulses of the veins are not felt due to low pressure in blood flow through the body.

The four chambers of the heart play significant roles in the circulatory system. oxygen -poor blood enters the superior vena cava, into the right atrium, passing the tricuspid valve, into the right ventricle. From the right ventricle, blood is passed into the pulmonary artery, back into the left atrium from the pulmonary veins, passing the bicuspid valve (mitral) into the left ventricle and out into the aorta. The valves control blood flow from one chamber into the other. The right atrium receives oxygen-poor blood and the left atrium receives oxygen-rich blood. Both the right and left ventricles are responsible for pumping their designated blood out of the heart into the body.
