Why do the walls of trachea not collapse when there is less air in it
How are oxygen and carbon dioxide exchange in our body during respiration
Answers
1. The trachea is not a very collapsible organ like the oesophagus or the food pipe.
So there needs to be a force.
This force helps in the movement of trachea.
This leads to the closing of trachea which is not possible when the air is less.
This is because there is no force and force is required for .
2. when the blood with O2 goes to the cells in our body the oxygen is taken by the cells and the CO2 is given out of the cells and is carried by the blood to the heart and then to the lungs , but when we take in O2 with the help of respiration the lungs release the carbon dioxide out and take the oxygen and supply it to the blood and again blood containing O2 goes to our body cells . This is how exchange of oxygen with carbon dioxide takes place.
HOPE IT'S HELPFUL MARK AS BRAINLIST IF.
walls of trachea will not collapse when there is less air in it..bcoz there some specialized bones which prevent it from collapsing....
o and carbon dioxide exchange in alveoli of lungs in respiration
