For inhalation, your intercostal muscles contract. While doing so, this moves your rip cage outwards and upwards. The diaphragm contracts moving downwards. So, this increases your volume of the chest so the pressure decreases inside the chest. Therefore the air rushes in to balance with the pressure.

For exhalation, it is the complete opposite... So, first off, your intercostal muscles relax so the rip cage moves downwards and inwards. Then, the diaphragm relaxes, and moves upward into a dome-like-shape. This action decreases the volume of your chest so that the pressure increases and air rushes out to balance the pressure.

Answer from: Hellokittyjam35

When you exhale you breathe outwards and when you inhale you breathe inwards. Breathing is performed by the respiratory system, which consists of the lungs, trachea, bronchi and diaphragm. The first step to breathing is inhalation. Inhalation occurs when oxygen-rich air is sucked into the body. The diaphragm initiates inhalation by contracting the muscles. As the muscles contract, the chest cavity becomes larger. With the larger cavity the lungs do not feel pressure from the outside. As the air is pulled into the body, the pressure is again equalized. Once the oxygen is in the blood and ready to be pumped throughout the body, the final step of exhalation must be completed. To exhale, the muscles of the diaphragm relax which adds pressure to the chest cavity and forces air from the alveoli into the bronchioles. The air continues to move through the tubes reaching the bronchi. The air containing the carbon dioxide then travels through the trachea and back out the mouth or nose.

my hamster died and my second hamster i got after that one died as well. i also lost two birds named rainbow and kiwi, (they didn't die, they flew off and escaped). i lost a cat named omi, and a dog named snoopie. the best way i got over it is, paying my respects, and just thinking that they were in a happy place. as well as just remembering but not thinking about it all the time, just do fun activities and try not to think about it too much. hope you feel better. i'm sorry about your loss. : (
