An arterial blood gas is a blood test in which a syringe is used to draw a small blood sample from an artery.
The pulmonary artery is the main artery that carries blood to your lungs.
The artery leaving the right ventricle, also called the pulmonary artery, takes blood to the lungs to exchange gas.
Oxygen. The pulmonary artery carries carbon dioxide instead.

The aorta is a large artery that carries oxygenated blood from the heart to the body. The alveoli are small air sacs in the lungs where gas exchange occurs. The connection between the aorta and alveoli is through the process of oxygen exchange, where oxygen from the inhaled air diffuses into the blood in the alveoli and is then carried by the aorta to the body tissues.

There is no such thing as arterial blood gas. When they draw blood it is drawn into a vial that has a vacuum, so it may appear that they are drawing gas, but no such gas exists. Also, when they draw blood they draw it from a vein.

The radial artery is the recommended site for arterial blood gas sampling. It is preferred over other sites like the brachial or femoral arteries due to lower complication rates and easier accessibility.
Carbon dioxide leaves the blood and goes into the alveoli where it can then be breathed out of the body. It is also at this point that oxygen passes into the blood to be carried to where it is required for respiration - carbon dioxide being a by-product of respiration.
