Back

Pathogens are harmful microorganisms, such as bacteria and viruses, that can cause disease in the body.

Front

Which body systems are most important for fighting pathogens in the blood?

Back

The immune system and the circulatory system work together to identify and eliminate pathogens.

Front

What role does the nervous system play when you touch something sharp?

Back

The nervous system sends signals to the brain, which triggers a reflex action to move away from the sharp object.

Front

How do the muscular and nervous systems interact during a reflex action?

Back

The nervous system sends impulses to the muscles, causing them to contract and move away from danger.

Front

What happens to your breathing rate during exercise?

Back

Breathing rate increases to supply more oxygen to the muscles that are working harder.

Front

What is the function of the respiratory system?

Back

The respiratory system is responsible for taking in oxygen and removing carbon dioxide from the body.

Front

How does the circulatory system support the respiratory system?

Back

The circulatory system transports oxygen from the lungs to the body's cells and carries carbon dioxide back to the lungs.

Front

What is the relationship between the respiratory and muscular systems during physical activity?

Back

The respiratory system provides oxygen needed by the muscular system to produce energy for movement.

Front

What is the role of the circulatory system in removing waste?

Back

The circulatory system helps transport waste products, like carbon dioxide, to the lungs for exhalation.

Front

How do Olympic sprinters' body systems interact during a race?

Back

The respiratory system increases oxygen intake while the circulatory system delivers that oxygen to the muscles for energy.
