Asker's rating. 1  Fred is correct the smaller the number the bigger the metal. 2  12 gauge is thinner than 7 gauge. 3  The gague refers to the thickness of the metal in question. the issue of strenght is really determines by the type of metal, not necessarily it's thickness.
The left ventricle pumps oxygen-rich blood out of the heart and into an artery called the aorta. From the aorta, blood branches out into a series of ever smaller tube-like vessels: arteries, arterioles and finally capillaries. The capillaries deliver the blood's oxygen and nutrients to cells.
Where does blood go after it leaves the right ventricle? It goes through the pulmonary artery (the only artery with deoxygenated blood as far as I know) to the lungs to be oxygenated. It then returns to the heart through the pulmonaâ¦ry vein (only vein with oxygenated blood as far as I know) and into the left atrium.
