We cant do this because the food can do to the trachea [wind-pipe] instead of oesaphogus [food-pipe]

Around 30,000 years ago Neanderthal man disappeared to be replaced by the Cro-Magnon people. These were responsible for the cave paintings, and were the earliest signs of civilization.They looked similar to us, the same physique, the same brain and the same looks. Unlike all previous hominoids who roamed the earth, they could choke on food. This may seem a small point, but the evolutionary change that pushed the larynx deeper into the throat, thus making choking a possibility, brought the possibility of a well articulated speech. Other mammals have no contact between their air passages and oesophagi. They can breathe and swallow at the same time and food can not possibily go down the 'wrong way'. With Homo Sapiens,food and drink must pass over the larynx on the way to the gullet and therefore there is a very real chance that some will be inhaled. In modern humans, the lowered larynx is not in position from birth. It descends sometime between the ages of three and five months - curiously, the precise period when babies are likely to suffer from Sudden Infant Death Syndrome. However, the descended larynx explains why you can speak and your dog can not

The windpipe is in front of the foodpipe. The upper part of the windpipe is the larynx. When we swallow, a soft flap called the epiglottis covers the opening of the windpipe so that food goes into the foodpipe and not the windpipe. Therefore, we cannot breathe and swallow at the same time.

Because your respiratory tract and your digestive tract have a common area called the esophagus and when you swallow food or liquid a little flap called the epiglottis shuts and blocks the larynx so no food or fluid accidently goes into the lungs, and if nothing can go in then air can also not come out at that time.

WHEN WE GULP OUR FOOD A THIN FLAP CALLED EPIGLOTTIS GETS CLOSED TO ENSURE THAE FOOD DOES NOT ENTER INTO THE TRACHEA,THUS WE CANNOT BREATH WHILE EATING

SOMETIMES WHEN WE TALK WHILE EATING THE EPIGLOTTIS GETS OPENED(TO GIVE OUT AIR,WHILE TALKING)AND FOOD ENTERS INTO TRACHEA AND FOR MUCH TIME WE STRUGGLEWITH IT.THATS IT WE ARE ADVISED NOT TO TALK WHILE EATING
