Depends on the bone. Heavy bones like the femur are extremely resistant to breaking, as is the skull. Smaller bones tend to be jointed in a way that lets them flex away from breaking forces. To actually put a number to this belongs more in the realm of the clinical laboratory, as the answer is always going to be somewhat abstract. I can take a section of femur (in the lab), deliver measured vertical force until it fractures, and all I've discovered is what would happen to someone who was attentive enough to fall in an exact vertical plane, and remain in that position as impact settled in. Not real-world at all. That said, some bones bear internal pressures of up to a ton or more. Spines bear a huge amount of shearing stress and concentrated/angualr weight.
Human bones are thicker and denser; bird bones are thinner, hollow and mean less weight on the bird.
The human's bones need to support larger amounts of weight and withstand pressure, twisting, and other forces. The bones of the bird need to be light-weight so that the bird can acheive flight.
The average weight of human bones is around 14% of a person's total body weight. This means that for an average adult weighing 150 pounds, the bones would weigh around 21 pounds. However, bone weight can vary depending on factors such as age, sex, and overall body composition.
our bones are hard and strong , but they are not heavy . They are so light that the skeleton is less than one fifth of a person's total body weight . so , if you weigh fifty pounds , only about ten of those pounds are your bones .
Flight requires that the weight of the bird be kept as low as possible.
an average human(height-5ft 10 in)weighs around seventy to seventy five kg...but weight can always differ...sometimes bones are heavy, sometimes muscle or extra fat account for the extra weight...the weight of a human depends on his height...

Tobi says: Bird's bones are hollow to help them fly,obviously to reduce weight when they fly. Human bones, on the other hand, are not hollow. We need strong bones to do the things we do, eg: walking, skipping, jumping etc...
Human bones.
humming bird bones are hollow, while human bones are not holllow
No. There are 206 bones in Human body.
How do you remember the bones in the human body?
