CLINICAL MEDICINE

Detailed explanation-1: -The main job of the innate immune system is to fight harmful substances and germs that enter the body, for instance through the skin or digestive system. The adaptive (specific) immune system makes antibodies and uses them to specifically fight certain germs that the body has previously come into contact with.

Detailed explanation-2: -The immune system is a complex network of organs, cells and proteins that defends the body against infection, whilst protecting the body’s own cells. The immune system keeps a record of every germ (microbe) it has ever defeated so it can recognise and destroy the microbe quickly if it enters the body again.

Detailed explanation-3: -If an antigen enters the body and B-cells recognize it (either from having had the disease before or from being vaccinated against it), B-cells will produce antibodies. When antibodies attach to an antigen (think a lock–key configuration), it signals other parts of the immune system to attack and destroy the invaders.

Detailed explanation-4: -Vitamin C, found in citrus fruit, including oranges and strawberries, as well as tomatoes, broccoli and spinach. Vitamin E, found in almonds, sunflower and safflower oil, sunflower seeds, peanut butter and spinach. Zinc, found in oysters, red meat, poultry, beans, dairy products.

Detailed explanation-5: -For example, if bacteria get into your body through your mouth, the immune system would send white blood cells to kill the invading germs. Sometimes the white blood cells win and you don’t get sick.
