That would be the immune system
Antibiotics are used to fight infections. without them we rely entirely on the ability of our immune system to destroy attacks on our system. The immune system is a wonderful thing, however it is not good enough in many instances to contain dangerous infections, fortunately Antibiotics are capable of destroying many pathogens (A bacterium, virus, or other microorganism that can cause disease.) that would otherwise overcome our immune system.
If your immune system stopped working, your body would be unable to defend itself against infections and diseases. This could lead to severe illnesses, recurring infections, and even life-threatening conditions. It is crucial for the immune system to function properly to protect your overall health.
you will die
Infections, cancer, foreign bodies, sometimes itself.
When the immune system is compromised, it is known as an immunodeficiency. This condition can result from various factors, including genetic defects, certain medical treatments, or infections like HIV/AIDS. Individuals with immunodeficiency are more susceptible to infections and may have difficulty fighting off diseases that a healthy immune system would typically manage. Treatment often focuses on managing infections and supporting the immune system.
If the immune system stopped working, the body would be unable to defend itself against infections from bacteria, viruses, and other pathogens. This could result in severe illness, increased susceptibility to common infections, and increased risk of developing serious diseases.
Very little ... but the respiratory system would slowly heal. Never back to normal, but in 6 weeks the chronic infections would begin to clear, and in about 2 years the lungs would be about as healthy as they would ever be.
HIV invades helper T cells, which then begin to produce HIV soon after their infected. As helper T cells die, the immune system gradually weakens and becomes overwhelmed by pathogens that it would normally detect and destroy.
The digestive system needs other body systems to provide oxygen and fight off infections. Alone, the digestive system would simply not function and die.
The skeletal system holds the body together. Without it, we would not be able to stand upright and we would be like jelly.
Yes, opportunistic infections often emerge as a result of deficiencies in the immune system, which can be due to conditions like HIV/AIDS, certain cancers, or the use of immunosuppressive medications. When the immune system is compromised, it becomes less effective at fighting off pathogens that would normally be controlled by a healthy immune response. This allows normally harmless organisms, such as specific bacteria, viruses, fungi, or parasites, to cause infections. Consequently, individuals with weakened immunity are at increased risk for these infections.
