Indicate which statements are true. Correct all false statements by changing the underlined words.
__________ Phagocytes exhibit chemotaxis toward a pathogen.

Verified step by step guidance

1. Understand the key terms in the statement: 'Phagocytes exhibit chemotaxis toward a pathogen.' Chemotaxis refers to the movement of cells toward or away from a chemical stimulus.
2. Recall that phagocytes are immune cells that move toward pathogens by detecting chemical signals released by the pathogens or damaged tissues.
3. Evaluate the statement: Phagocytes do indeed exhibit chemotaxis toward pathogens, meaning they move in response to chemical signals to reach the site of infection.
4. Since the statement is true, no correction is needed for the underlined words.
5. Summarize that phagocytes use chemotaxis as a mechanism to locate and migrate toward pathogens for immune defense.

Key Concepts

Phagocytes

Phagocytes are immune cells that engulf and digest pathogens and debris. They play a crucial role in the innate immune response by identifying, ingesting, and destroying harmful microorganisms.

Chemotaxis

Chemotaxis is the movement of cells toward or away from chemical signals. In immunology, phagocytes move toward higher concentrations of chemical signals released by pathogens or damaged tissues to locate infection sites.

Pathogen Recognition

Pathogen recognition involves detecting molecules unique to pathogens, triggering immune responses. Phagocytes recognize these signals, which guide their chemotactic movement and activation to eliminate the threat.
