In the model below, discover what happens to the individuals in the sea star population when exposed to harmful bacteria. These phagocytes are part of the innate immune system. These cells provide non-specific responses, which means they respond to anything they view as foreign or an invader.
The Innate Immune System:
The innate immune system is characterized by general, non-specific responses. The non-specific response is part of the innate immune system. Responses include sneezing, coughing and diarrhea.
Physical barriers, such as the skin, also contribute to innate immune protection.
The innate immune system also protects us with chemicals such as acids in the stomach and enzymes in tears.
