Each beat ejects approximately 2 oz. of blood or 5 quarts each minute. During periods of exercise or physical activity as much as 37 quarts a minute may be pumped. On the average a 70-year old heart has beat approximately 2.5 billion times and has pumped approximately 35 million gallons of blood. The total blood volume of a 150 pound man is approximately 6 quarts. Alveoli and associated capillaries are the basic lung unit.
Capillaries is where the oxygen is utilized by the body.
They are where arteries become veins. A more thorough explanation of capillaries and what they do will be discussed later. One critically injured patient may be required 40-60 units of blood components in a matter of hours. Please continue to support our Community Masonic Blood Program by donating, having friends and family donate as often as possible. A wonderful and achievable goal is 50,000 units if everyone will do their part.
