5i Curricular: Science
Body talk
We cantaskt help it, but we all sneeze, yawn, blush, hiccup, cough or even snore from time to time. But what exactly is going on in our bodies when we do all these things?
Yawn
No one knows for sure why we yawn, but one theory is that when youtaskre tired or bored, you don’t breathe as deeply as usual, so yawning helps you to take more oxygen into the blood. Other scientists say that yawning stretches the muscles and lungs and increases the heart rate, helping us to stay more alert. Most people seem to agree about one thing, though... yawning is contagious!
Even animals and unborn babies yawn!
Sneeze
When something such as dust, pollen or a virus irritates the inside of our nose, a message goes to the brain. The brain then tells six different muscles including your eyelids to push air out through your nose at up to 160 kmph.
Cough
A cough В an important way of clearing your airways, throat and lungs of irritations. When you cough, you breathe in and dose your vocal cords. As you release the air, you make a barking noise - a cough.
Blush
Ittasks no secret that we blush when wetaskre embarrassed, but why? Well, when you feel self-conscious, your body releases adrenalin which increases the blood flow to your face.
Babies dontaskt blush. You only blush when you become aware of other peopletasks thoughts and feelings.
Hiccup
We get hiccups when something irritates the diaphragm musde below the lungs that helps pull air into them. When we eat or drink too much, or when we feel nervous or excited, the diaphragm pulls down air in a jerky way. When this air meets your voice box, you make a hiccup sound.
Snore
When you are asleep and air cantaskt move freely through your mouth or nose, parts of your mouth and throat vibrate and cause snoring. Reasons why the air can’t get through might include an allergy, a cold or being overweight. Studies say that about 45% of men and 30% of women snore regularly.
