The pulmonary system goes from heart to lungs to heart while the systemic system goes from heart to body to heart
when we breathe in your diaphragm goes down and the lungs expand and the air goes there. and im right. (:
Oxygen goes from the lungs to the tissues via the blood stream and CO2 goes back to the lungs via the blood stream
Trachea goes from the mouth to the lungs. Esophagus goes from the mouth to the stomach.
Just like particles of different charge are attached to each other, particles tend to go from place where's concentration bigger to places where there's lower. No energy is required for this process. Once, lungs are wide open, air goes in because the pressure in lungs is smaller than one around us. Blood that's full of CO2 comes into the lungs. Since there's more CO2 in the blood than there's in the lungs, and more O2 in the lungs than there's in the blood, O2 goes to the blood and CO2 goes to the lungs, thanks to this process. Then, the blood that full of O2 goes to the cells. Cells are always full of CO2 since they're constantly performing oxidation . Then, the same thing happens. CO2 comes out of the cells and goes to the blood since there's less of it in the blood, and O2 goes into the cells. Thanks to this particles trait, there's no energy that is used for O2 going to the blood and cells. I hope I made this more clear for you, and I'm sorry for my bad English.
Blood goes to the lungs oxygen poor and comes out of the lungs oxygen rich.

oxygen.
You breath.
Lungs contain lots of blood. Blood goes to the lungs to pick up oxygen.
cigarettes have tar in them that goes into your lungs which is toxic to your lungs and since it doesn't go anywhere it causes disease in your lungs.
Carbon dioxide, Waste product, goes from the cell to the lungs. So the question is lung to the cell, not positive, but oxygen.
you breath it in and the air goes into your lungs and helps pump the blood around
helps filter the hair before it goes in your lungs
