Immune Cells
These white blood cells are the first to arrive at infection cells
What are neutrophils?
This gland is where T cells mature
What is the thymus?
A baby receives antibodies through breast milk
What passive natural immunity?
This type of pathogen can be treated with antibiotics
What is bacteria?
This system delivers white blood cells to sites of infection
What is circulatory systems?
These immune cells help activate B cells and cytotoxic T cells
What is helper T cells (CD4+)?
These small structures filter lymph and house immune cells
What are lymph nodes ?
Getting a vaccine for measles provides this type of immunity
What is active artificial immunity ?
This pathogen needs a host cell to reproduce
What is a virus?
This system helps the immune system by expelling pathogens via sneezing or coughing
What is respiratory system?
These cells destroy virus-infected and cancerous cells without needing antibodies
What are cytotoxic T cells (CD8+)?
This organ stores white blood cells and removes pathogens from the blood
What is the spleen?
Receiving antivenom after a snake bite provides this
What is passive artificial immunity ?
These eukaryotic organisms can cause infections like athlete's foot
What is fungi?
This system increases body temperature during infection to slow pathogen growth
What is endocrine system?
These innate cells recognize and attack abnormal cells during perforin and granzymes
What are natural killer (NK) cells?
These lymphoid tissues protect the respiratory and digestive tracts (like tonsils)
What is MALT (Mucosa-associated lymphoid tissue) ?
This form of immunity uses T cells to destroy infected host cells
What is cell-mediated immunity ?
Malaria is caused by this kind of pathogen
What is a parasite?
These organs help eliminate pathogens via urine
What are kidneys?
These antigen-presenting cells digest pathogens and display antigens to T cells
What are dendritic cells?
These vessels return excess fluid from tissues to the bloodstream
What are lymphatic vessels
This branch of immunity uses memory cells and improves with repeated exposure
What is adaptive (acquired) immunity ?
This virus attacks helper T cells and weakens the immune system
What is HIV?
This system produces hormones like cortisol, which can suppress or modulate the immune response
What is endocrine system?
