What conditions affect diffusion?
Factors that may affect Diffusion rates are: Temperature, Concentration, Different tissue types, Molecular size, Surface area to volume ratio.
How does surface area to volume ratio of a cell affect rate of diffusion?
The surface area to volume ratio of a cell affects the rate of diffusion in that the higher the ratio, the faster the rate of diffusion. This is a directly proportional relationship.
What influences the rate of diffusion?
The rate of diffusion increases with temperature. The rate of diffusion also increases with the concentration gradient and the surface area.
How does the reduced number of alveoli affect the xchange of oxygen and carbon dioxide?
the coughing causes the walls of some of the alveoli in the lungs to burst. when this happens the surface area of the lungs in contact with the air is reduced.
What diseases affect the alvioli?
Alveoli are the minute sacs inside the lungs that expand and contain a membrane that allows the exchange of oxygen and carbon dioxide, called respiration. One of the major diseases that affect the alveoli is emphysema. That is when the walls between the alveoli breaks down and they lose surface area and become less efficient at respiration.
How does doubling the radius of a cylinder affect the volume?
Doubling the radius quadruples the volume.
How does surface area affect diffusion rate?
Diffusion is the movement of particles across a selectively permeable membrane, from a high concentration to a low concentration. So the larger the surface area, the quicker the rate of diffusion because there is more space to diffuse in.
What factor affects the rate of diffusion?
Diffusion refers to the process where substances from a highly concentrated area move to a place with a lower concentration. The three factors that affect the rate of diffusion are temperature, concentration gradient and the molecular weight of the substances.
What factors affecting the diffusion?
There several physical factors that affect the rate at which particles diffuse. These include: the size of the particle, the temperature, the concentration difference, the diffusion distance, the surface area, and permeability.
How does surfactant affect the total air flow into lungs?
Surfactant is similar to a detergent, it keeps the fluid coating the lining of the alveoli from creating surface tension. This allows the alveoli to expand without hindrance, and allows greater air flow.
How does doubling the height of the cylinder affect the volume?
It doubles it.
How does doubling the height affect the volume?
If all other dimensions are left unchanged, doubling the height doubles the volume.
