The human immune system consists of millions of cells and protein that work together to fight disease and infection.
Human immune system is able to remember and recognize viruses and bacteria that once attack the body before, so that they can fight them more effectively in the future.
Human immune cells can move towards the site of infection or disease and fight it there.
Antibodies produced by the human immune system can survive in the body for years, even a lifetime.
Human immune system can also recognize abnormal or infected cells, such as cancer cells, and against them.
There are two types of human immunity, namely the innate immunity and the immunity obtained.
The human immune system can be influenced by factors such as eating, exercise, stress, and lack of sleep.
Some types of food, such as garlic and blueberry, are known to have a positive effect on the human immune system.
The human immune system can also be influenced by the surrounding environment, such as air pollution and radiation exposure.
The human immune system tends to decrease with age, so that older people are more susceptible to disease and infection.
