The healthy human immune system responds to pathogens with both specific and nonspecific processes. Which of the following models represents a nonspecific response?
An immune response that occurs in the human body is shown above. This activity helps to do which of the following?
Produce antibiotics to control disease
Provide protection against a specific pathogen
Provide protection against all types of pathogens
Eliminate harmful gene alterations
What is the body's first line (non-specific) of defense against infection by foreign organisms?
antibodies
lymph nodes
white blood cells
the skin
White blood cells are an important part of the human immune response. Two types of white blood cells, neutrophils and macrophages, act as phagocytes. Phagocytes perform which of the following functions in the human body?
They produce antibodies.
They bind to antigens and develop into plasma cells
They form a barrier against pathogens.
They engulf and destroy bacteria
Which of the following describes a way that a person's health can be affected by heredity?
A person with a family history of obesity is more likely to catch a common cold.
A person with a family history of high blood pressure is more likely to have heart disease.
A person with a family history of obesity is less likely to enroll in a weight loss plan.
A person with a family history of cancer is less likely to be screened for cancer.
Many species of bacteria have become resistant to antibiotics because antibiotics have been so widely used. Now, bacteria that used to be killed by antibiotics are more difficult to treat. What is the best way to proceed in dealing with this public health problem?
Antibiotics should no longer be used.
Antibiotics should be made available to anyone without a prescription.
Antibiotics should only be prescribed to people with bacterial infections.
Anti-viral medications should now be used instead of antibiotics.
What are memory T Cells?
The kills infected body cells
They help the immune system respond quicker if the same pathogen enters the body again
They signal B Cells
They cause Inflammation
What is a vaccine?
A weakened pathogen injected in the body to produce immunity
Temporary immunity that develops as natural exposure
An overreaction of the immune system
Medicine that helps after you're infected
What is the role of the immune system?
To pump blood throughout the body
To protect the body from disease-causing agents
To contain disease-causing organisms to a single area of the body
To give Ms. Genosa something to test us over
The process by which harmless antigens are introduced into a person's body to produce active immunity is called:
Vaccination
Immunity
Passive Immunity
Protective Barrier
A chemical that kills bacteria or slows their growth is called:
Antivirals
Vaccine
Antibiotics
Antigen
