How does the immune system interact with other body systems to protect the organism?
It only works alone to fight disease
It works with the cardiovascular system to transport white blood cells throughout the body
It digests food to provide energy for fighting infections
It controls muscle movement
Which of the following is an example of how the muscular and respiratory systems interact?
Muscles in the chest help move air in and out of the lungs during breathing
Muscles produce hormones for the respiratory system
The respiratory system digests food for the muscles
The muscular system filters waste from the air
What is the primary function of the cardiovascular system?
To break down food into nutrients.
To transport oxygen and nutrients to cells.
To remove waste products from the body.

Muscular system
Which of the following is a function of the nervous system?
To digest food and absorb nutrients.
To coordinate and control body activities.
To pump blood throughout the body.
To support and protect the body.
What role do muscles play in the muscular system?
They produce hormones for growth.
They provide structural support.
They facilitate movement by contracting and relaxing.
They transport nutrients to cells.
Which of the following systems is directly involved in the breakdown and absorption of nutrients?

In what ways do the cardiovascular system and the immune & lymphatic system work together to fight infection?
Both systems have white blood cells (WBC) which will fight the infection.
Both systems have red blood cells (RBC) which will fight the infection.
Both systems have platelets which will fight the infection.
Both systems have plasma which will fight the infection.
