Final answer:
The total blood volume for a 75kg man is approximately 5.3L, which is about 8 percent of his body weight. The range for adult males is generally between 4.7 and 5.7 liters of blood. correct answer is c) 5.3L .
Step-by-step explanation:
The total blood volume for a man who weighs 75kg is approximately 5.3 liters (L). This calculation is based on the guideline that blood constitutes about 8 percent of adult body weight, and the average for adult males typically ranges from 5 to 6 liters. Given that the man in question weighs 75kg, 8 percent of his body weight would yield a total blood volume of 6 kg (75kg x 0.08 = 6kg), which is equivalent to 6 liters, considering 1 liter of blood approximately weighs 1kg. Among the options provided, 5.3L is the closest accurate choice.
It's important to remember that individual variations such as overall health, hydration status, and physical condition could lead to some deviation from this calculation. However, generally speaking, the adult male body does indeed contain between 4.7 and 5.7 liters of blood, as noted in the referenced materials. This value is consistent with the approximate 5 to 6 liters that encompasses the average range for blood volume in men.
