Explain the importance of cells being able to work together and communicate with each other for the human body to function correctly.
Cells must work together and communicate to carry out processes at the correct time and respond to changes in the environment, ultimately leading to specific physiological responses.
How do individual cells know to carry out specific processes at a given time?
