Vascular resistance is due to friction between blood and the walls of the blood vessel. Which of the following causes low vascular resistance?

• obesity

• dehydration

• high blood pressure

• cholesterol levels within normal range

Which of the following would be a logical argument for conducting a genetic screening rather than a pathogenic screening to identify a disease or condition?

• A) A genetically carried disease or condition, which can be treated by altering environmental factors, would have no bearing on pathogen transmission.

• B) A genetically carried disease or condition, which is contagious, should be identified early to increase the odds of containment; whereas a pathogenically transmitted condition will confine itself to one population.

• C) A genetically carried disease or condition, which can be treated with a vaccination, should be identified early to increase the odds of an infant's survival; whereas a mother's immunity would protect an infant from pathogens.

• D) A genetically carried disease or condition, which can be treated with gene therapy, should be identified early to increase the odds of an infant's survival; whereas a mother's immunity would protect an infant from pathogens.

Mary feels sick for a week and decides to go to the doctor. The doctor tells her that she has a viral infection and does not prescribe antibiotics to treat her illness. Within a couple of days Mary is feeling better. Which statement best describes Mary's path to recovery?

• Mary was already feeling better and didn't need to go to the doctor's office.

• The nonspecific immune response destroyed the virus through inflammation two weeks after Mary went to the doctor's office.

• The specific immune response produced antibodies that rid her body of the viral infection after it learned the properties of the viral molecule.

• Antibiotics produced by Mary's body stimulated her immune system to produce enough antibodies against the virus and destroy the viral infection.

Which of the following shows the lists in the correct order?

• First Trimester - 2; Second Trimester - 1; Third Trimester - 3

• First Trimester - 1; Second Trimester - 3; Third Trimester - 2

• First Trimester - 3; Second Trimester - 2; Third Trimester - 1

In the human immune system, there are physical and chemical defenses that protect against viruses, bacteria, and other pathogens. Which statement describes an event that occurs in a nonspecific immune response?

• A vaccine is injected to a person to prevent the flu.

• Phagocytes and macrophages engulf foreign materials.

• T-lymphocytes eliminate infected body cells and tumor cells.

• B-cells produce antibodies that will aid in future viral infections.

If a pathogen penetrates the skin barrier, which immune response would occur first?

• Antibodies would develop to make a vaccine.

• The temperature would increase at the infection site.

• Mucus would be produced to prevent further infection.

• Platelets would increase the flow of blood from the wound.
