Chapter 6 Quiz

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.

After an initial infection, B-cells recognize the measles virus. How is this helpful in human immune response?

• The B-cells use this recognition to defend the body against other pathogens, such as bacteria.

• The B-cells more quickly recognize and respond to any other virus that invades the body.

• The B-cells produce antibodies more quickly if the measles virus is encountered again.

• The B-cells transfer this recognition to T-cells, which will then devour the viruses.

• Lymph nodes

• White blood cells

• The skin

What does phagocytosis mean?
