First the body breathes in the air which is sucked through the nose or mouth and down through the trachea (windpipe). The trachea is a pipe shaped by rings of cartilage. It divides into two tubes called bronchi. These carry air into each lung.

Ten interesting facts 1.The right lung is just a bit bigger than the left lung.2.Women and children have a faster breathing rate than a man3.Our air gets warmed up and cleaned by the hairs in the nose4.When someone is asleep they breath about 12 to 15 times a minute.5.The highest recorded speed of a sneeze travelling is 165 kilometres an hour. WOW THAT’S PRETTY FAST!!!

6,We lose about a half a litre of water a day from breathing.7,The surface area of people’s lungs is as big as a tennis court.

8.The capillaries in the lungs would extend 1,600 kilometres if placed end to end 9.Inside the lung, the tubes divide into smaller and smaller tubes called bronchioles.

10.At the end of each of these tubes are small air balloons called alveoli.

Last few questions ……

The trachea……

The TracheaThe Trachea also known as the wind pipe is used to pass air that is breathed in through the nose or mouth into the lungs. The diagram below shows the

Trachea.
