To pump blood throughout the body
What is the main organ of the circulatory system?
The heart
This long tube carries food from your mouth to your stomach
Esophagus
These organs take in oxygen and release carbon dioxide
Lungs
The respiratory system brings in oxygen and the circulatory system moves the oxygen around the body in the blood.
What is the job of the lungs?
To bring in oxygen and release carbon dioxide
What does your heart pump through your body that carries nutrients and oxygen?
Blood
This organ churns food and mixes it with digestive juices
The stomach
Your body releases this waste when you exhale
Carbon dioxide
What two systems are at work: Food is broken down into nutrients and then are moved through the body.
What is the job of the stomach?
To break down food into smaller parts.
Through blood vessels
These useful substances from food help your body grow and get energy
Nutrients
Oxygen
Which systems are at work: Capillaries surround the air sacs in the lungs, where blood picks up oxygen.
respiratory and Circulatory
Where does the digestion process begin?
The mouth
These blood vessels carry blood back to the heart
Veins
Large Intestine
These tiny air sacs move oxygen into the blood and carbon dioxide out.
Alveoli
What systems are at work: The lungs bring oxygen into the body, and the digestive system provides nutrients. Cells use both to release energy
Digestive and Respiratory
How do the heart and lungs work together?
The lungs add oxygen into the blood, which the heart pumps through the body.
What is the job of the circulatory system?
To transport blood, nutrients and oxygen throughout your body.
What is the job of the digestive system?
What is the job of the respiratory system?
To breathe in oxygen and to breathe out carbon dioxide.
The lungs add oxygen to the blood, and the small intestine adds nutrients. Together, these materials are carried by this system to body cells.
