What does the structure of lungs enable them to do?
The structures in the lungs enable the lungs to exchange oxygen for carbon dioxide in the blood. The structure are also designed to help the lung protect themselves from irritants.
What three adaptations do birds have for flight?
Their forelimbs have become modified into wings for flying. All modern birds evolved from ancestors that could fly. Some modern birds, like penguins and ostriches, don't fly today. But they still have feathers and wings. Feathers probably evolved from reptiles' scales. Both feathers and scales are made of the same tough material as your fingernails. Birds' feet and legs have scales on them. 2 The bodies of birds are adapted for flying. Many of a bird's bones are hollow which makes birds' bodies lightweight. Flying birds have large chest muscles that move the wings. Birds have feathers that help them fly. The long flight feathers on the wings and tail help birds balance and steer. In addition, birds have a system of air sacs in their body that connect to the lungs. The air sacs enable birds to extract much more oxygen from each breath of air than other animals can. Birds need extra oxygen to release large amounts of energy to power their flight. Their four-chambered heart also helps a bird get more oxygen. The advantage of a four-chambered heart is that there is no mixing of oxygen-rich and oxygen-poor blood. Blood that arrives in the bird's body tissues has plenty of oxygen. 3 Birds also have well-developed brains and keen eyesight. In order to fly, birds must have very quick reactions. When approaching a tree or cliff, a bird has only a few seconds to spot a place to land safely and avoid crashing. Most birds have keener eyesight than humans do. Birds' eyes are much larger in relation to their body size than humans' eyes.

What are birds bones like?

How does oxygen help in your breathing?
It doesn't help, its almost the entire purpose of breathing which is to get enough oxygen fast enough to maintain our aerobic metabolism. When breathing fails to get enough oxygen fast enough the body must switch back to more primitive fermentation anaerobic metabolism, which produces lactic acid and the resulting buildup of lactic acid in tissues causes pain.
Give the uses of common bird structures?
Birds have wings which help them fly. They have claws that enable them grasp branches firmly. Their beaks enable them to pick up food with ease.
What happens when your oxygen saturation drop when you are on and off the ventilator?
When your oxygen saturation levels drop, your blood is not carrying enough oxygen to provide your body the levels it needs. If they drop low enough, your body will shut down and you can die. If you are hooked to a ventilator, this will help the body increase the oxygen saturation levels in your blood, potentially saving your life.
