Why is diffusion in the respiratory system important for your body?

Answer 1

This is the process where the oxygen enters the blood stream and the CO2 is removed. Random motion can transport the oxygen through the lung's membrane and the CO2 thus you don't have to work as hard to breathe and force the oxygen in and the CO2 out of the cell walls, you only need to force it in and out of the lungs themselves. This system of exchange is a passive one so less energy is needed.

Diffusion is a natural process created because of the tendency of things to become more chaotic unless energy is spent to impose order. This is often known as entropy.

According to Wikipedia: http://en.wikipedia.org/wiki/Diffusion
"Diffusion is the phenomenon of random motion causing a system to decay towards uniform conditions. For example, diffusing molecules will move randomly between areas of high and low concentration but because there are more molecules in the high concentration region, more molecules will leave the high concentration region than the low concentration one. Therefore, there will be a net movement of molecules from high to low concentration. Initially, a concentration gradient—a smooth decrease in concentration from high to low—will form between the two regions. As time progresses, the gradient will grow increasingly shallow until the concentrations are equalized.

Diffusion is a spontaneous process (more familiarly known as a "passive" form of transport, rather than "active"); it is simply the statistical outcome of random motion. Diffusion increases entropy, decreasing Gibbs free energy, and therefore is thermodynamically favorable. Diffusion operates within the boundaries of the Second Law of Thermodynamics because it demonstrates nature's tendency to wind down, as evidenced by increasing entropy."

Answer 4

Respiration is the process in which gets oxidized and energy is released.it also involves the taking of o2 co2.
Through diffusion oxygen gets dissolved into the blood and transportated throughout the body.
