What exactly do white blood cells inspect?

Answer 1

White blood cells, or leukocytes, inspect and monitor various components of the body's immune system, primarily looking for pathogens such as bacteria, viruses, fungi, and parasites. They also recognize and respond to abnormal cells, including cancerous cells. By doing so, they help maintain the body's defense against infections and diseases, ensuring a robust immune response when threats are detected. Additionally, white blood cells can interact with other immune cells to coordinate a comprehensive response.
