Homeostasis and Cell Transport
Homeostasis is the process by which cells maintain the internal conditions that they need to support life. This can be generalized to the heat that our bodies generate to keep us warm and support chemical reactions or the microscopic movements of molecules across cell membranes. This is what powers that larger changes that keep our bodies in equilibrium. As a matter of fact, most of the processes to maintain homeostasis in cells occours in the form of diffusion of materials across membranes. However, there are several different ways that this can take place. Depending on the type and size of molecules diffusing across, different processes can take place. Below are listed links to pages explaining each one.
