Question

Quizplus · Accepted Answer

The human immune system is primarily responsible for protecting the body against infections caused by bacteria and viruses. It does this by recognizing and attacking foreign invaders, such as viruses and bacteria, while leaving healthy cells alone. The immune system also helps to promote tissue repair after injury or damage, but this is not its primary function. It does not promote tissue transplants or defend against hypertension. It also does not adjust for changes in climatic conditions.
