Because the action of your chest moving, coupled with your diaphragm - is what draws air into the lungs.
it is important so cars can move about
So when molecules are heated, the heat is so intense that they have to move around for them to cool down.
No. There is no voluntary muscle in the breast. They can flex the chest muscles under the breast and so cause them to move.
Energy is important because it helps a person get through every day chores and it helps you sit up straight, lay down, and move. If you didn't have engery then you wouldn't be able to do anything. And so that's why engery is important.
aerodynamics is important in the motor industry because it allows cars to move easier and faster along the road and also stops car lift by using down forces.
The aim of chest compressions is to squash the heart under the chest. Every compression 'squashes' the heart, this causes all of the blood to be pumped out of the heart and off round the body, taking the oxygen with it (assuming you're doing the breaths as well). You then come back up, allowing the heart to refill before you compress again. In this way you are reproducing a heartbeat for someone who doesn't have one.
Neural impulses cause diaphragm and chest cage to move down wards and outwards respectively so that air can move into lungs Cough reflex is mediated by nerve impulses/reflexes
So you can move to your full potential
In the third (far right) column you move the third box down, which is a package, to the second row (swap with the grey chest); still in the third column you then choose the second last box, which is a green suitcase, and move it right, out by itself; once this is done you then move the box (or green suitcase) on the top left, left so then there is a row of green suitcases. Then you're done.
it is important so that we cool down
This is because gravity is pulling you down, so you don't have to pedal as much downhill. Uphill, on the other hand, gravity is STILL pulling you down, so you have to fight to move forward AND to move against gravity.
It's important to have your shoulders up and your back straight so as not to crunch your diaphragm. Be sure you are breathing from your diaphragm and not your chest by placing a hand on your low belly and seeing if it moves up and down. Deep breathing is the most important part.
