Classify the responses in the given situations as part of innate immune response or adaptive immune response.

Innate immunity forms the first line of defense (skin and mucous membranes) and second line of defense (defensive cells, inflammation, fever)

The function of innate immunity is to block invading microbes into destroying those which succeed in penetrating the body.  

Example of innate immune system

-swelling occurs in the area where you have scratched (Inflammation)  

Adaptive immunity is known as the third line of defense (T cells, B cells and antigen presenting cells). Another name for adaptive immunity is acquired immunity.

-An example of adaptive immune response is a liver transplant from a donor to the recipient ( T cells or B cells)

-A person vaccinated for typhoid.

when atoms of different types of elements join together, they make molecules called compounds. water consists of compound molecules made up of 2 hydrogen atoms and 1 oxygen atom. this is why it's called h2o. water will always have 2 times the number of hydrogen atoms as oxygen atoms.
