pump blood
remove waste
voluntary movement
This is a complex system in our body that transports needed materials. It includes the heart and blood vessels.
skeletal system
respiratory system
digestive system
circulatory system
What is the biggest function of the respiratory system?
to pump blood
to help us digest food
to take in oxygen and release carbon dioxide
to help us fight disease and infection
Which two body systems are primarily responsible for gas exchange between the body and the environment?
skeletal and muscular
circulatory and respiratory
circulatory and digestive
respiratory and excretory
How does the respiratory system depend on the circulatory system in order to function?
The circulatory system brings waste gases to the lungs and exchanges them for oxygen.
The circulatory system provides structural support and protection to the respiratory system.
The circulatory system pushes gases out of the body through the mouth and nose.
The circulatory system sends messages to the lungs so that one can breathe in and out.
How does the immune system depend on the circulatory system in order to function?
The circulatory system produces antibodies used by the immune system.
The circulatory system sends bacteria and viruses to the immune system.
The circulatory system transports immune system cells throughout the body.
The circulatory system protects the immune system from diseases.
What is the most important function of the digestive system?
gas exchange
break down food into usable nutrients
voluntary movement
fight bacteria and disease
Which two systems work together to break down and transport nutrients?
muscular and respiratory
circulatory and skeletal
digestive and circulatory
endocrine and digestive
What is the biggest function of the muscular system?
to help digest food
to help us move
to help us breathe
to help us remove waste
This is a system in the body that includes the brain, spinal cord, and nerves. It coordinates and controls the body's actions.
digestive system
nervous system
circulatory system
