digestion
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.
Antibody
Insoluble particles can be removed from hot solution by filtration.
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.
Phagocytosis is a process where specialized immune cells called phagocytes engulf and digest foreign particles, such as bacteria or debris, to protect the body from infection and maintain tissue health. Phagocytes recognize the foreign particles through specific receptors on their cell surface, engulf them into a vesicle called a phagosome, and then fuse this vesicle with lysosomes containing enzymes to break down the ingested material. The digested particles are then eliminated from the body.
The air is:- heated (to body temperature)- cleansed (foreign particles attach to the mucosa of the nasal cavity and thusly removed before they reach the lungs).- moistened (the humidity of the air increases)All of these mechanism are designed to help the lungs to a better supply of air.
