This oxygenated blood is pumped to the left hand side of the heart in the pulmonary vein and enters the left atrium. From here it passes through the mitral valve, through the ventricle and taken all around the body by the aorta. Blood contains antibodies, nutrients, oxygen and much more to help the body work.ertebrate blood is bright red when its haemoglobin is oxygenated and dark red when it is deoxygenated. Some animals, such as crustaceans and mollusks, use hemocyanin to carry oxygen, instead of hemoglobin.
In the test apply a load equal to one half of the cold cranking amperes (CCA) rating of the battery for 15 seconds. During the load test, the voltage reading from car battery terminals should not go lower than 9.6V for ambient temperature 70F (21C). At 30F (-1C) the voltage can go no lower than 9.1V.

That said, many batteries pack it in around the 5-year mark. The battery in my vehicle is over 7 years old now and I just had it load tested because I wondered.
