Cell Communication

Mr. Andersen explains cell communication by drawing parallels with human communication methods. He uses analogies like Post-it-Notes, emails, and Facebook posts to describe cell-to-cell contact, local regulators, and hormonal communication. The video covers how cells communicate directly, over short distances, and over long distances using examples like immune responses, neurotransmitters, and growth hormones.
