Quizplus · Accepted Answer

Most of the chemical signals that a cell receives in a multicellular organism come from other nearby cells. These signals, which can be in the form of hormones, neurotransmitters, or growth factors, help to coordinate the activities of different cells and tissues within the organism. While the external environment and the nervous system can also play a role in cellular signaling, they are not typically the primary sources of signals for cells within the body. The lymphatic system is primarily involved in immunity and the maintenance of fluid balance, and is therefore not a major source of signaling molecules for most cells.
