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.
12 volts nominal.   A 12 volt car lead-acid battery will measure about 12.2 at full charge and no load. Car charging systems usually keep the voltage around 14 when the car â¦ is running, though it might drop down if accessories are in use (lights, heater fan, wipers).2.0 at 25% charge. With the engine running you should get a reading of between 13.5 & 15.5 volts if the alternator is working properly. 12VDC for most cars or 24VDC for some trucks or large vehcles. A fully charged 12 volt auto battery will read 12.6 volts with a digital volt meter.
