The average adult has about 1.2 to 1.5 gallons (4.5 to 5.5 liters) of blood circulating inside their body, said Dr. Daniel Landau, a hematologist and oncologist at the University of Florida Cancer Center – Orlando Health.

The total blood volume This amount can vary with age, gender, weight, height and different medical conditions. Normally blood makes 7- 8% of human body weight. In adults, this amounts to 4.5- 6 quarts (5- 6 litres) of blood. One unit of blood is roughly equivalent to one pint.

Approximately 32,000 pints of blood are used each day in the United States. Every three seconds someone needs blood. Just one pint of donated blood can help save as many as three people's lives. The average adult has 10 pints of blood in his or her body.

Is there an average amount? It's widely accepted that the average person loses between 30 and 40 milliliters, or two to three tablespoons, of blood during menstruation. But some research suggests that this figure may actually be closer to 60 milliliters, or about 4 tablespoons.

The average adult loses two to three liters of water a day through natural bodily functions, which is why it's so important to replace that missing water by ingesting two to three liters of fluid a day.

It is vital to have a MAP of at least 60 mmHg to provide enough blood to the coronary arteries, kidneys, and brain. The normal MAP range is between 70 and 100 mmHg.

During a regular donation, you will give around 470 ml of whole blood. This is about eight per cent of the average adult's blood volume. The body replaces this volume within 24 to 48 hours, and replenishes red blood cells in 10 to 12 weeks.

The average human has a mass of about 62 kg, or 62,000 grams. That means the average volume of a human is 62,000 cubic centimeters. To get the total volume of the human race, just multiply that by 7.6 billion: 470 trillion cc. That's a weird amount to grasp.

Normal Blood Count Ranges In general, the normal range for a red blood cell count is 4.5 to 5.5 million cells/mm3 if you're male and 4 to 5 million cells/mm3 if you're female. For white blood cell count, the normal range is 5,000 to 10,000 cells/mm3, and for platelets, the typical range is 140,000 to 400,000/mm3.

Iron is biologically important in the transport of oxygen by red blood cells from the lungs to the various organs of the body. In the blood of an adult human, there are approximately 2.64 × 1013 red blood cells with a total of 2.90 g of iron.

Between 8-12 pints of blood are in the body of an average adult. 08. One unit of blood is ~525 mL, which is roughly the equivalent of one pint. 09.

Two thirds of body iron is present in circulating red blood cells as hemoglobin. Each gram of hemoglobin contains 3.47 mg of iron; thus, each mL of blood lost from the body (hemoglobin 15 g/dL) results in a loss of 0.5 mg of iron.

Intracellular fluid (2/3 of body water) is fluid contained within cells. In a 72-kg body containing 40 litres of fluid, about 25 litres is intracellular, which amounts to 62.5%.

How Much? Under the usual conditions of life, 3 – 4 liters of fluids a day will provide 2.5 to 3 liters of urine volume, and this is enough.

It helps maintain normal blood pressure, supports the work of your nerves and muscles, and regulates your body's fluid balance. A normal blood sodium level is between 135 and 145 milliequivalents per liter (mEq/L). Hyponatremia occurs when the sodium in your blood falls below 135 mEq/L.

Blood types and donation During a regular donation, you will give around 470 ml of whole blood. This is about eight per cent of the average adult's blood volume. The body replaces this volume within 24 to 48 hours, and replenishes red blood cells in 10 to 12 weeks.

One unit of blood is equivalent to 1 pint or 450 milliliters, so 4 units of blood would be 1800 milliliters or 1.8 liters.
