What Are Innate and Acquired Immunity?

TL;DR

Innate immunity is the body's first line of defense, present at birth and non-specific, using barriers like skin and immune cells to fight infections. Acquired immunity develops over time through encounters with specific pathogens, creating tailored immune responses, such as antibodies against illnesses like chicken pox.

Transcript

We always hear about our qualities from people around us who compare us with our parents. We find people usually saying things like, she has got her excellent drawing skills from her dad or her beautiful singing is inherited from her mom! These are the qualities we inherit from our parents, and which are present since birth. But there are several q... Read More

Key Insights

• 🎁 Innate immunity is present since birth and helps fight off various infections non-specifically.
• ❓ Components of Innate immunity include physical, physiological, and cellular barriers.
• ⌛ Acquired immunity develops over time and is highly specific to encountered pathogens.

Questions & Answers

Q: What is the difference between Innate and Acquired immunity?

Innate immunity is present since birth and non-specific, while Acquired immunity develops over time and is specific to encountered pathogens.

Q: How do physical barriers contribute to Innate immunity?

Physical barriers like the skin and mucous coatings act as the body's first defense against infections.

Q: How does Acquired immunity work against specific pathogens?

Acquired immunity involves the body developing strategies to fight specific pathogens, such as synthesizing antibodies against the Chicken pox virus.

Q: What is the role of immunological memory in Acquired immunity?

Immunological memory allows the body to recognize previously encountered pathogens and mount a faster immune response.

Summary & Key Takeaways

• Humans have two types of immunity: Innate immunity, present since birth, helps fight off various infections non-specifically.

• Components of Innate immunity include physical barriers like skin, physiological barriers, immune cells like lymphocytes, and antibodies.

• Acquired immunity is developed over time and is highly specific to certain pathogens encountered, like the immune response to Chicken pox virus.
