Inside the lungs are tiny tubes known as the terminal bronchiole. Within these tubes are thing air sacs which transfer oxygen directly into the blood and remove carbon dioxide.
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!
The tiny air sacs in the lungs are alveoli
sacs are Synaptic vesicle.
No. They are called alveoli. Lymphocytes are a type of white blood cell.
