The respiratory and circulatory systems are close together by working and relying with each other. The respiratory system imports oxygen from the air and that oxygen goes through out the body by the circulatory system pumping the oxygen. That creates carbon dioxide, which the respiratory exports from the body.

First, let's distinguish active from passive immunity:
- Active immunity occurs in a direct exposure of individuals to live pathogens. The result is a development of a disease. After that, individuals acquire immunity to the disease.
- Passive immunity is induced by vaccines with antibodies for a disease, so the disease does not develop.

a. ACTIVE IMMUNITY - Bill had a disease, so it must be active immunity.
b. PASSIVE IMMUNITY - Bill got a vaccine and a disease did not develop, so it must be passive immunity.
c. PASSIVE IMMUNITY - Although, 3-month-old daughter did not get a vaccine, she has mother's antibodies from the milk so she will not develop a disease.
