Question

explain the purpose of the “rule of nines”. (p. 201)
describe an autograft vs. a homograft? (p. 200)

Explanation:

The "rule of nines" is used in medicine to estimate the percentage of body - surface area affected by burns. An autograft is a tissue graft from one part of a person's body to another part of the same body, minimizing the risk of rejection. A homograft is a tissue graft between individuals of the same species, and it may trigger an immune response and rejection.

Answer:

The purpose of the "rule of nines" is to estimate the percentage of body - surface area involved in burns. An autograft is a self - tissue graft with low rejection risk, while a homograft is a graft between same - species individuals with potential rejection issues.
