• The human immune system consists of different cells, including T cells and B cells, which work together to fight infections and diseases.
• The immune system also contains a special protein called immunoglobulin, which can recognize and bind pathogens such as viruses and bacteria.
• T killer cells (killer) can recognize infected cells and kill them to prevent the spread of disease.
• Cells B produces antibodies to fight pathogens and help prevent re-infections in the future.
• Fagocytic cells, such as macrophages, can swallow and digest pathogens to kill them.
• The immune system can also produce inflammatory responses to fight infections and accelerate healing.
• Some organs, such as spleen and bone marrow, also play an important role in the human immune system.
• The human immune system can adjust to different pathogens and build immunity to infections that often occur.
• Vaccination is a way to increase the human immunity to certain diseases by giving a small dose of pathogens or harmless parts of pathogens.
• Some factors, such as stress, lack of sleep, and poor eating patterns, can weaken the human immune system and increase the risk of infection and disease.
