whats prevents food from going down your lungs
Yes, both the mouth and nose help to moisten and warm air before it enters your lungs.
no because the lungs help you breath but the heart helps to get blood in your system
after the oxygen from the air enters the lungs,the oxygen gets sent to the heart and then travels through the arteries with the blood.
With their lungs rather than through their lungs, but yes - both dolphins and kangaroos breathe with lungs.
No. Humans have lungs but worms do not.
The lungfish has both gills and lungs.
If both lungs were removed, the person would die.
That is a good question! You have a pleura, that surround the lungs. You have inner and outer layers (visceral and parietal layers). Both are connected to each other. In fact you have a balloon, in which your lungs grow. You take out the air from the balloon and you get the pleura. So both the come together at the blood vessels and bronchi. The lungs are totally elastic organs and collapse to small ball, if air enters the pleura. This elasticity of lungs create the negative pressure in the pleura. The negative pressure in pleura keeps the lungs in expanded condition. You have little fluid in the pleura. This reduces the friction between the outer and inner layers of pleura.
No. Just lungs.
Both are functioning properly.
Lungs are totally elastic organs. They are kept in position by negative pressure in visceral and parietal pleura. There is no gas in cavity between both pleura. In fact both pleura are part of one one collapsed balloon. Very small amount of fluid in cavity between pleura keeps it lubricating. If air accidentally enters there, then there is a condition called as Pneumothorax. There is also a condition called as Tension Pneumothorax. Which is an emergency.
Pupils "constrict" when light enters, and "dilate "when the lighting dims
