Skin
Mucus
Stomach Acid
Antibodies
A 3 month old baby contracts a virus called whooping cough (pertussis) after receiving the first of a sequence of 3 necessary DPT vaccines designed to prevent 3 diseases (diphtheria, pertussis, and tetanus). The vaccines are given at 2, 4, and 6 months of age to allow the body to develop specific immunity against these diseases. After the infant recovered from the disease, the doctor informed the parents that from now on the infant would only need the DT (diphtheria, tetanus) part of the vaccine. Why does the infant only need the DT vaccine?
The infant had the first of a series of vaccines which caused the disease
The infant had the pertussis disease and has already produced antibodies against the disease.
The infant had the first of a series of vaccines which protected him from getting the disease.
The infant had the pertussis disease and will get diphtheria in the future.
Many times people visit the doctor requesting antibiotics to treat colds and viral infections. How is the doctor justified in offering the patient treatment options that do not include antibiotics for these cases?
Colds and viruses should be first treated with viral therapies and then when the body begins to recover, antibiotics can be used. Otherwise, the use of antibiotics is not effective at all.
Side effects from antibiotics are severe when used for colds and viruses. Any use of antibiotics for colds and viruses will only make the patient more ill and ultimately make the patient's recovery time longer.
Antibiotics can weaken the immune system when used for colds and viruses, whereas other medications are not so hard on the immune system during these types of illnesses.
If a doctor provides an antibiotic to treat colds and viruses, any bacteria in the patient's body will be killed, but a few will survive. Those few survivors may become resistant to antibiotics needed for real bacterial illnesses.
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
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
How does your body determine which cell to kill?
looks at the DNA fingerprint by each cell
uses the marker proteins
talks to the helper T cell about what to destroy
the brain tells it which cells belong
Getting antibodies from breast milk is an example of acquired immune response
True
False

What is an antigen?
a protein that triggers an immune response
"hand cuffs" for pathogen
substance made by B cells
chemical that makes the immune cells divide
Which cell will poke holes in cancer cells?
cytotoxic T cell
B cell
helper T cell
macrophage
Which cell does HIV attack?
macrophage
antibody
Helper T cell
