Capillaries . The smallest of the blood vessels: capillaries.
What is the name of the organ that you use to breathe in oxygen?
the air goes into your lungs. In your lungs there are billions of tiny air sacs. Surrounding each air sac is a network of blood capillaries. The air sacs and the blood capillaries are separated by a thin membrane. Across this membrane the air sacs give the blood capillaries oxygen and they blood capillaries give the air sacs carbon dioxide. We breathe out this carbon dioxide!
How are the lungs and the capillaries connected?
The lungs contain air sacs called alveoli which are surrounded by blood capillaries to allow gaseous exchange.
What tiny air sac is surrounded by blood capillaries?
Alveoli which are in your lungs
Which substances are exehanged between the blood in the capillaries and the air in the air sacs?

What are the small tubes called that carry air to the air sacs?
Capillaries.
How do the circulatory and respiratory system work together in the air sacs?
