Most of us think that birds can fly in the sky only because they have large wings and a tail for balance. But if these two things were present with man, would he have flown to such a height? I mean, most people get scared after going to a small height, so can you feel the clouds at such a height? No human can withstand such a height. Of course, it can’t. But then the question is how do birds do it? Because we see these birds flying in the sky for weeks and even months, birds are actually specially designed to fly at high altitudes. Because their lungs do a lot more work than human lungs. Because birds have a higher amount of hemoglobin, they have more copies of oxygen inside their lungs, which are tiny blood vessels that carry oxygen. And this is exactly the reason why they do not feel homesick even at high altitudes. They easily adjust the pressure of their body and the gases in the air.

You must have noticed that when we feel cold, we start shivering. Do you know why this happens? Actually, we shiver because our body tries to keep us warm. As we know that the normal temperature of our body is 37 degrees Celsius, and this temperature is controlled by a part of our brain called the hypothalamus. It is quite less if we don’t wear warm clothes. So we feel cold. And the temperature of our body also decreases. Hypothalamus immediately detects this decrease in temperature. And then the hypothalamus sends signals to our muscles to rapidly contract and relax. And that is why we tremble. Heat is generated by rapidly contracting and relaxing the muscles. And this heat warms our bodies. In this way, the temperature of our body is maintained.
