How breathing works: The respiratory system in human beings consists of the following organs: nose, pharynx, trachea, bronchi and lungs.
Inhalation: During inhalation, muscles and diaphragm contract and the ribs are pushed outward and upward. The diaphragm flattens and the chest cavity increases in volume. This reduces the air pressure inside the lungs. The atmospheric air gushes in through the nostrils to equalize the air pressure. |

Exhalation: During exhalation, the chest muscles relax and ribs are pushed downward and backward. The diaphragm becomes dome-shaped. As a result, the volume of the chest cavity decreases. The pressure of air inside the lungs increases and air is thrown out through the nostrils.
Tesla couple of days back shared an update on the ventilator it’s developing to address the shortage caused by the COVID-19 pandemic.
In a new video Tesla’s engineers show off two versions of the ventilator, a prototype model with its components laid out across a desk, as well as a packaged model that shows how it might look when used by a hospital. |
