Which of the following types of immunity is acquired as a result of having the disease?
Natural passive
Artificial passive
Natural active
Artificial active
The Correct Answer is C
A. Natural passive immunity occurs when antibodies are passed from mother to child, either during pregnancy or through breast milk. This is not related to having the disease.
B. Artificial passive immunity is the transfer of antibodies from an external source, such as through antibody-containing blood products, to provide immediate protection against a disease.
C. Natural active immunity is acquired when an individual is exposed to a pathogen and the immune system responds by producing antibodies and memory cells. This type of immunity occurs after contracting the disease.
D. Artificial active immunity is gained through vaccination, where a person is exposed to a harmless form of the pathogen (such as inactivated or attenuated form), prompting the immune system to create a defense without causing illness.

Explanation
A. As previously noted, the length of the thoracic cavity increases, not decreases, during the contraction of inspiratory muscles.
B. The diaphragm moves downward (not upward) when it contracts, allowing the lungs to expand.
C. The contraction of the diaphragm and external intercostals increases the diameter of the thoracic cavity, providing space for the lungs to expand and fill with air. This is the correct answer.
