Step 1

mast cells would release antibodies.

Answer

Mast cells play a pivotal role in the immune response by releasing antibodies, specifically Immunoglobulin E (IgE), which helps in the recognition and neutralization of foreign materials. This process is crucial for initiating an inflammatory process.

Step 2

the skin tissue would become pale and cold.

Answer

The inflammation can lead to vasoconstriction, which reduces blood flow to the affected area, resulting in pale and cool skin tissue. This response is part of the body's way to minimize further injury and manage the inflammatory process.

Step 3

the capillaries would become more permeable.

Answer

Inflammation promotes increased permeability of the capillaries, allowing essential immune cells and proteins to move from the blood into the surrounding tissues. This helps to effectively target and fight the embedded foreign object.

Step 4

red blood cells would leave the blood vessels and engulf foreign material.

Answer

While red blood cells primarily function to transport oxygen, the influx of white blood cells is critical during inflammation. White blood cells, particularly macrophages, migrate out of the vessels to engulf and digest the foreign material, thus protecting the body from infection.
