The diffusion of oxygen and carbon dioxide?
The respiratory system uses the diffusion of oxygen and carbon dioxide. You inhale the oxygen which goes through the alveoli and thew capillaries in the lungs and you exhale it through the same section you inhale from. Therefore they diffuse together.
How do the rates of diffusion of oxygen and sulfur dioxide compare Molar masses Oxygen is 32 gmol and sulfur dioxide is 64 gmol?
Oxygen diffuses 1.4 times as fast as sulfur dioxide.
Many small aquatic organisms move oxygen and carbon dioxide through their skin by the process of?
Diffusion
What state is carbon dioxide on earth?
Carbon dioxide can be a solid, liquid or gas. At standard temperature and pressure it is a gas.
What are the factors affecting the rate of diffusion?
Factors Affecting the Rate of DiffusionSizeSmall molecules can slip by the polar heads of the phospholipids and through the membrane to the other side. Oxygen gas, carbon dioxide and water can move in this manner. Very large molecules like proteins cannot diffuse across the membrane at all.ShapeGlucose is able to get into cells much faster than other sugars. This is accomplished by facilitated diffusion. A carrier protein specific for glucose (not other sugars) combines with it on the outer surface, closes around it, and then opens to the inside of the cell where the glucose is released. The carrier then returns to its original shape and is ready to transport another glucose molecule. These carriers can move up to 100 glucose molecules per second across the cell membrane.ConcentrationThe greater the concentration gradient between the outside and inside of the membrane the greater the rate of diffusion. If the concentration of oxygen outside the cell increases then it will diffuse more quickly into the cell. The opposite is also true. If a muscle cell for example is working hard and using up large quantities of oxygen in cellular respiration producing ATP, then the low levels inside the cell will increase the concentration gradient compared to outside and the rate of diffusion of oxygen into the cell will increase. The same conditions in a muscle cell would create high concentrations of carbon dioxide inside the cell and increase the rate of diffusion from inside to outside.Charge (+/-)Ions or molecules with a charge cannot pass through the lipid bilayer by diffusion. Other mechanisms involving protein carriers and ATP energy are required. The sodium/potassium ion pump is an example of this type of transport.Lipid SolubilityLipid soluble molecules can move through the lipid bilayer. Generally these molecules are other lipids. Steroid hormones like testosterone and estrogen are examples of such molecules. This easy access to cells explains the powerful and wide ranging effects of such hormones.TemperatureIn general, increases in temperature cause all molecules to move faster. Diffusion is a passive movement of molecules so quicker molecule movement translates into quicker diffusion.Rate of diffusion increases as: * Diffusion distance decreases * Concentration gradient increases * Surface area increases
How is the movement of oxygen similar to the movement of carbon dioxide in the body?
They both follow a simple diffusion gradient : from high pressure to low.

How do the small molecules of oxygen and carbon dioxide move through the cell membrane?
They move via diffusion across a gradient.
How is diffusion used when cells remove carbon dioxide?
Carbon dioxide moves out of the cells from a higher to lower concentration across the cell membrane. Then the CO2 moves through the capillary wall across the diffusion gradient. The diffusion process is repeated at the capillary/alveolar junction.
What is the term that pertains to the exchange of gasses between the blood and alveolar air?
The air of the alveoli has a greater partial pressure of oxygen than blood and a lower partial pressure of carbon dioxide. This creates a gradient across the membrane. The gases diffuse from an area of high concentration to an area of low concentration, thus the carbon dioxide moves out of the blood into the air and the oxygen moves from the air into the blood. According to Fick's law this diffusion is porportional to (diffusion gradient x membrane permeability)/thickness of the membrane also called cellular respiration
How would the movement of CO2 be affected if the concentration of CO2 in the lungs was equal or higher than the concentration in the blood?
If the concentration of CO2 in the lungs was higher or equal the concentration in the blood, there will be no diffusion of CO2 in the air of the lungs. The person will suffocate in this situation.
What system help the fish do?
well... they use vibrations to hear, and their gills are used as a respiratory organ; Oxygen passes from the water into the blood at the gills. Removal of carbon dioxide also occurs, as the blood containing high concentrations of the waste gas goes to the gills, and the carbon dioxide diffuses out into the water down a diffusion gradient (external water has lower concentrations of carbon dioxide than levels in the blood, so this sets up a diffusion gradient.) this enables the fish to extract 80% of the available O2 from the water water so... it depends on what you mean by do.
Why is diffusion?
Diffusion takes away carbon dioxide and unwanted waste from the cells.
What is the Diffusion of gases between alveoli and blood?
The Diffusion is the exchange of oxygen (O2) and carbon dioxide (CO2) between the alveoli and the blood. So blood that is pumping through the capillaries in the lungs has a low concentration of O2 and a high concentration of CO2, in the alveoli it is high concentration O2 low concentration CO2. Therefore the 2 gases exchange across the alveoli membrane by diffusion trying to establish a concentration gradient.
Why is diffusion important?
Diffusion takes away carbon dioxide and unwanted waste from the cells.
Does carbon dioxide move into cells?
Yes, during diffusion
Carbon dioxide passes out of a cell by?
