The part of the respiratory system that pushes and pulls the lungs to draw air in and out is the diaphragm. Here's a step-by-step explanation:

1. The diaphragm is a dome-shaped muscle located at the base of the lungs and thoracic cavity.

2. When you inhale, the diaphragm contracts and moves downward. This increases the space in your chest cavity, into which your lungs expand.

3. The decrease in pressure inside the chest cavity allows air to flow into the lungs.

4. When you exhale, the diaphragm relaxes and moves upward into the chest cavity. This decreases the space for the lungs and pushes air out.

5. The intercostal muscles, located between the ribs, also assist in this process by moving the rib cage in and out during breathing.

So, the diaphragm and intercostal muscles work together to allow us to inhale and exhale.
