Questions and Answers

What defines the non-specific immune system?

It requires previous exposure to pathogens to activate.

It specifically targets pathogens with antibodies.

It primarily involves memory cells for future infections.

It includes barriers like skin and mucous membranes. (correct)

Which of the following statements is true about the specific immune system?

It operates mainly through physical barriers.

It acts slowly, taking days to respond.

Non-specific immune system

A part of the immune system that provides general defense against pathogens through barriers and cells.

Specific immune system

A part of the immune system that targets specific pathogens by creating antibodies and memory cells.

Antibodies

Proteins produced by the immune system to identify and neutralize pathogens.

Memory cells

Cells that remember past infections to improve future immune responses.

Study Notes

Immune System Summary

The immune system has two main parts: nonspecific and specific.
The nonspecific immune system acts as a rapid defense against pathogens. It includes physical barriers like skin and mucous membranes, and cells like neutrophils.
The specific immune system is more targeted, creating antibodies and memory cells (lymphocytes) to respond more quickly to repeated infections.

Description

Explore the two main parts of the immune system: nonspecific and specific. The nonspecific immune system serves as a rapid defense using physical barriers and various cells, while the specific immune system focuses on targeted responses with antibodies and memory cells.
