What is diffusion?
From high to low is the flow
Passive diffusion
On its own.
Faster and shorter distances
Bulk transport
Heart and lungs push what you need
What affects diffusion
Hot temperature increases diffusion
Colder temperature slows down diffusion
Diameter
Viscosity
Viscosity
Thicker solution
Oil and honey, diffusion will be slower
Molecular radius
A molecule with bigger diameter, making diffusion slower
