What is the amount of blood contains in the human body?
Answers
Answer:
7 percent of body weight.
Explanation:
The amount of blood in the human body is generally equivalent to 7 percent of body weight. The average amount of blood in your body is an estimate because it can depend on how much you weigh, your sex, and even where you live.
Babies: Babies born full-term have about 75 milliliters (mL) of blood per kilogram of their body weight. If a baby weighs about 8 pounds, they’ll have about 270 mL of blood in their body, or 0.07 gallons.
Children: The average 80-pound child will have about 2,650 mL of blood in their body, or 0.7 gallons.
Adults: The average adult weighing 150 to 180 pounds should have about 1.2 to 1.5 gallons of blood in their body. This is about 4,500 to 5,700 mL.
Pregnant women: To support their growing babies, pregnant women usually have anywhere from 30 to 50 percent more blood volume than women who are not pregnant. This is about 0.3 to 0.4 additional gallons of blood.
Sometimes the amount of blood in the human body can differ based on where you live. For example, people who live at high altitudes have more blood because there isn’t as much oxygen at higher altitudes.
