There really isn't much similarity between a balloon and a lung. The surface of a balloon is smooth...
lungs have alveolar sacks that increase the surface area of the lung tissue. This also increases the cross membrane exchange from and to the lung and into the capillaries supplying oxygen and expelling carbon dioxide.
the reason why a ballon left inside a car on a hot summer day become larger is because the air particles inside the ballon collise with the ballon walls more frequently. I guess......
Alveoli in the lungs.
diffusion of gases (oxygen and carbon dioxide) to & from air in lungs and capillaries in alveoli
No, the trachea is a passageway for air to travel to and from the lungs. Oxygen and carbon dioxide are exchanged in the alveoli of the lungs, where they diffuse across the walls of the alveoli and capillaries.
a sponge
you need it to survive
It is one to two cell thick
No. They expand because there's a diaphragm that sits below the lungs and make them expand
Chimps Breathe with lungs. Very, very similar to human anatomy.
Ballon d'Or was created in 1956.
Ballon d'Or ended in 2009.
Inhaled oxygen will diffuse through the walls of the lungs. It will also diffuse through the walls of red blood cells so it can be carried all over the body.
