The test used to measure how much oxygen is taken in with every heartbeat is called pulse oximetry. This test estimates the oxygen saturation levels in the blood by measuring the absorption of infrared light in pulsating blood.
5000 liter of blood every day

The larger the animal, the slower the heartbeat. A rat's heartbeat is like a bee buzz...

The heart makes the sound when it pumps and circulates the blood in your body, opening and closing valves. With every beat, there is a distinct 'lub-dub' noise.
Because it can block off the circulation of blood going to your heart, which can cause heart attacks.
An average heart pumps 2.4 ounces (70 milliliters) per heartbeat. An average heartbeat is 72 beats per minute. Therefore an average heart pumps 1.3 gallons (5 liters) per minute.

The thicker your arteries, the more blood pressure it takes to pump it through. If your arteries are clogged with blood vessels, it does not let as much blood flow by as originaly possible, so the body needs to push the blood through it harder, making your heart beat faster, therefore increasing your heart rate. If your heart rate is high, it means that your heart is not working as hard to pump blood through your arteries. So it is healthier to have a higger heart rate than a lower one.
Low levels of sodium can thin the blood and lead to variety of different heart problems such as a irregular heartbeat or low blood pressure. Fortunately it can easily be corrected by adding more salty foods to your diet.
