Foreign particles are primarily removed from the body through the immune system and various physiological mechanisms. The respiratory system uses cilia and mucus to trap and expel inhaled particles. In the gastrointestinal tract, foreign materials can be eliminated through digestion and excretion. Additionally, immune cells like macrophages and neutrophils identify and engulf foreign particles, facilitating their removal from tissues and the bloodstream.

Snot can be helpful to the body. It traps foreign particles and helps the body get them out. It can also be a problem.
This is a neutrophil.
Antibodies are used to fight from foreign particles (pathogen generally) entering in the body of an individual.
They fight infections, and protect our body from foreign particles.
The body produces macrophages to try to break down foreign objects in the body. Splinters can also be safely removed with tweezers.
White blood cells, particularly phagocytes like macrophages and neutrophils, are responsible for engulfing and digesting foreign particles, pathogens, and cellular debris. However, reticulocytes are immature red blood cells, not foreign particles; they are part of the normal process of erythropoiesis. While white blood cells do play a role in clearing damaged or dying cells, their primary function is to combat infections and protect the body from foreign invaders. Thus, while they can interact with reticulocytes, their main role is not to target them as foreign particles.
Antibody
Insoluble particles can be removed from hot solution by filtration.
When foreign particles like pollen enter the body, the immune system recognizes them as potential threats. This triggers an immune response, including the release of histamines and other chemicals that cause inflammation, leading to symptoms such as sneezing, itching, and nasal congestion. In people with allergies, the immune system overreacts to these harmless particles, resulting in exaggerated responses. Additionally, antibodies called IgE are produced, which can sensitize the body to future exposures.
Antibodies are proteins released by a type of white blood cell called lymphocytes. They destroy hostile microbes in the body.
Yes they can. The splinter will be un-sterile, and is a foreign object to the body. The body would start to attack it and eventually, pus would form if it were not removed.
