What are phagocytic cells?
Cells that release histamine during the inflammatory response
Cells that eat pathogens and destroy them
Cells in the immune system with four-part receptors shaped like a Y
Cells in the immune system with two chains
The Correct Answer is B
A. Cells that release histamine during the inflammatory response. Cells that release histamine during inflammation are mast cells, not phagocytic cells.
B. Cells that eat pathogens and destroy them. Phagocytic cells, such as macrophages and neutrophils, engulf and digest pathogens in a process called phagocytosis.
C. Cells in the immune system with four-part receptors shaped like a Y. Cells with Y-shaped receptors are B cells, which produce antibodies, not phagocytes.
D. Cells in the immune system with two chains. T cells have two-part receptors but are not classified as phagocytes.

Correct Answer is A
Explanation
A. Inflammatory response. The inflammatory response is the body's automatic reaction to tissue injury, involving processes like vasodilation, swelling, and the recruitment of immune cells to the affected area.
B. Innate immunity. While innate immunity includes the inflammatory response, it refers to the broader set of nonspecific defenses the body uses against pathogens.
C. Adaptive or acquired immunity. Adaptive immunity is the body's specific immune response, involving T cells and B cells, not the immediate reaction to tissue injury.
D. Vasodilation. Vasodilation is a part of the inflammatory response, but it is not the full process.
Correct Answer is ["A","C"]
Explanation
A. N. gonorrhoeae: This bacterium is a significant cause of PID as it can ascend from the cervix to the upper reproductive tract, leading to inflammation.
B. T. pallidum: This bacterium causes syphilis, not PID.
C. Chlamydia trachomatis: This is another primary cause of PID, often co-infecting with N. gonorrhoeae.
D. Peptostreptococcus: While this anaerobic bacterium can be involved in PID, it is not one of the major causes.
E. M. genitalium: This bacterium is associated with urethritis and PID but is less commonly referenced compared to N. gonorrhoeae and Chlamydia trachomatis.
F. C. albicans: This is a fungus (yeast) that causes candidiasis, not a bacterial cause of PID.
