It is the middle of the winter and like everyone else you have caught a cold, your body relies on your ___________ to help boost your immune system.

A.) plasma
B.) red blood cells
C.) white blood cells
D.) platelets

C.) White blood cells

The correct answer is C) white blood cells.

To understand why white blood cells help boost the immune system, it's important to know what they are and how they function. White blood cells, also known as leukocytes, are a vital component of the immune system. They are responsible for defending the body against infectious diseases and foreign invaders like bacteria and viruses.

When you catch a cold or any other illness, your body responds by producing more white blood cells. These cells help to identify and attack the pathogens responsible for the infection. They do this by either engulfing and destroying the invaders or by producing antibodies that neutralize the pathogens.

To specifically boost the immune system during a cold, it is important to take certain measures. Make sure to get plenty of rest and stay hydrated by drinking fluids. Consuming a balanced diet that includes foods rich in vitamins and minerals, such as fruits and vegetables, can also support immune function. Additionally, practicing good hygiene, such as washing your hands frequently and avoiding close contact with others who are sick, can help prevent further infections.

While all the options given in the question are components of blood, it is the white blood cells that specifically play a vital role in boosting the immune system when you have a cold.
