Study Notes
Innate Defense: Physical Barriers
- Skin is a protective barrier against microbes, with tightly packed epithelial cells.
- Mucous membranes, such as those in the eyes, digestive system, respiratory system, and reproductive system, act as barriers and contain antibacterial or antiviral substances, including saliva, tears, and mucous secretions.
- Normal flora compete with pathogens for resources, including attachment sites on epithelial cells and essential nutrients.
Natural & Artificial Immunity
- Immunity refers to the body's resistance to infectious diseases.
- The immune system recognizes foreign organisms through specific immune cells.
- It activates immune cells to produce responses, such as antibodies.
- The immune response targets the organism for destruction.
