What are the key elements of the immune response to viruses?
a) Physical barriers and natural chemicals are the first line of defense against viruses. The innate immune response is activated, involving interferons, natural killer cells, and macrophages. If the infection is not resolved, the adaptive immune response is activated, involving lymphocytes T and B.
b) The skin and cough are the first barriers encountered by the virus. Once inside the host cells, the innate immune response is activated, involving interferons, natural killer cells, and macrophages. If the infection persists, the adaptive immune response is activated, involving lymphocytes T and B.
c) The skin and digestive enzymes are the first barriers encountered by the virus. Once inside the host cells, the adaptive immune response is activated, involving interferons, natural killer cells, and macrophages. If the infection is not resolved, the innate immune response is activated, involving lymphocytes T and B.

A alternativa correta é a letra A) Barreiras físicas e produtos químicos naturais são a primeira linha de defesa contra os vírus. A resposta imune inata é ativada, envolvendo interferons, células natural killer e macrófagos. Se a infecção não for resolvida, a resposta imune adaptativa é ativada, envolvendo linfócitos T e B.
