Answer 2

Here are some fun facts about the respiratory system:

1)The average person breathes in 13 pints of air per minute.

2)People yawn because the brain senses low levels of oxygen in the lungs.

3)In humans, the right lung is larger than the left lung to accommodate the heart.

4)The fastest recorded sneeze is 120 miles per hour in speed.

5)300 million alveoli can be found in a pair of human lungs.

Answer 3

The respiratory system is amazing because two organs (lungs) that are essentially empty spaces keep humans and animals alive.

Within the otherwise empty space, numerous structures help to bring air into the lungs. This begins with the muscles that control the diaphragm and rib cage, along with basic life functions in the brain stem. As we inhale, the nose warms the air as it passes to the bronchus, looking like an upside down tree trunk. Going further, the main bronchus splits (like tree branches) into brochioles. At the ends of these smaller air passages inside the lungs are aveoli, looking like clusters of tiny grapes.

The aveoli are fascinating structures with a membrane that allows oxygen and carbon dioxide to pass through to and from the bloodstream. When a person has emphysema, some of the aveoli collapse and because there is less surface area, less O2 & CO2 can pass through. This problem along with damage to the lung tissue makes it hard to get air OUT in emphysema or IN when a person has Asthma.

The respiratory system also helps us to cool off when overheated; helps keep the Ph normal in the body especially in certain diseases; etc.

Answer 4

The respiratory system is essential for life and without it we would perish.
