The structures that provide a huge surface area for the diffusion of gases are the alveoli in the lungs and the thin-walled capillaries surrounding them. Alveoli are tiny air sacs that dramatically increase the surface area available for gas exchange, allowing for efficient oxygen uptake and carbon dioxide release. Additionally, the branching structure of the bronchioles and the extensive network of capillaries contribute to this large surface area, facilitating rapid diffusion.

Why is diffusion greater in gasses than in solids?
Diffusion is greater in gases than in solids primarily due to the differences in particle arrangement and movement. In gases, particles are widely spaced and move freely at higher speeds, allowing them to spread out rapidly and mix with other gases. In contrast, solids have closely packed particles that vibrate in fixed positions, limiting their ability to move and disperse. This restricted movement in solids results in significantly slower diffusion rates compared to gases.
Percentage of how many gases are there?
In the air around us there is 78% nitrogen 21% oxygen 1% other gasses
What are two the most common gasses found in air and what are their percentages?
Gases in air are nitrogen about 79%, oxygen about 20% and other gases 1%
Who is Dr Fred Whipple and explain his hypothesis?
Whipple came up with the "dirty snowball" concept of comets; that the head of the comet is primarily ice and frozen gasses bound together by dust, gravel and rocks. This explains the nature of the "tail" of the comet; as the frozen gasses sublimate away (change from solid to gas, without an intervening liquid state) the gas is carried away by the solar wind and by pressure of the sunlight itself.
What are the chemical families on the periodic table?
Well, several are, and from left to right. Alkali metals Alkaline earth metals. Transition metals. Metaloids. Nonmetals. Halogens. Nobel gasses.
Why do our lungs have a huge amount of capillaries?
It is because your body requires a lot of surface area for diffusion of gasses into the blood.
Does diffusion happen best in liquids?
The rate of diffusion is fastest is gasses, but as we can't see the gases ,it can be seen it liquids, but in liquids the rate of diffusion is comparatively slower than gasses and it can be easily observed....
What gasses are located on Uranus' surface?
methane carbon dioxide gases that do not provide life
What is the function of caplillaries?
Diffusion of gasses & dissolved substances into and out of the blood.
What are the movement of particles within solids liquids and gasses?
diffusion.
What are 2 gasses that move in and out of body by diffusion?
oxygen and carbon dioxide
How thin walls help the alveoli?
It allows for rapid diffusion of gasses.
Does neptune have a solid surface or is it made from liquids and gasses?
gasses
Why are the membraines in the alveoli thin?
membranes must be thin for efficient diffusion of gasses.
What does the close arrangement of alveoli and capillaries allows for?
This exchange allows easy diffusion of gasses back and forth.
Why diffusion rates of liquids are much less than diffusion rates of gasses?
Liquids diffuse at a slower rate than do gases because they have much less kinetic energy.
What rare the factor effectining the duffsuion of respiratory gasses?
The diffusion of respiratory gases is influenced by several factors, including the partial pressure gradients of the gases, the surface area of the respiratory membrane, the thickness of the membrane, and the solubility of the gases in the alveolar fluid. A higher partial pressure gradient enhances diffusion, while increased surface area facilitates greater gas exchange. Conversely, thicker membranes can impede diffusion, and the solubility of gases affects their ability to diffuse effectively across the membrane.
