Study Notes
Defense Mechanisms of the Body
- Individuals face constant threats from harmful invaders throughout life, starting from prenatal development.
- Types of invaders include:
- Bacteria
- Viruses
- Cancer cells
- Parasites
- Foreign (non-self) cells, such as those in tissue transplants.
Categories of Protective Measures
- Protective measures are classified into two key categories:
-
Non-specific defense mechanisms:
- Offer broad protection against a wide variety of potential dangers.
-
Specific defense mechanisms (Immunity):
- Targeted resistance against particular invaders.
- Develop immunological memory, which provides long-term immunity against specific infections.
-
Non-specific defense mechanisms:
Role of Antigens
- An antigen is defined as any substance that triggers an immune response, prompting the body to produce specific defenses.
