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!
The tiny air sacs in the lungs that take oxygen from the air and put it into the blood?
These tiny air sacs are called alveoli. These alveoli are surrounded by capilaries tiny blood vessells. These capilaries have holes that are to small for blood cells to escape but are big enogh for oxygen molecules to pass in to the blood stream and attach to the haemoglobin in your blood.

What happens to the blood as it flows through the capillaries in the lungs?
The CO2 or carbon dioxide is removed by the alveoli from the blood. The carbon dioxide is replaced with oxygen. The blood is then full of oxygen. Alveoli are tiny sacs in the lungs, surrounded by capillaries.
Why is there tiny veins in air sacs?
The thin walls of the blood vessels are capillaries around the alveolar sacs that permit diffusion of gases in every single red blood cell with oxygen inhaled ... they are thinner to improve the pressure gradient to allow more O2 in the capillaries, because the pulmonary capillaries have the lowest blood pressure in the body (normally)
What are tiny blood vessels in the human called?
