The trachea -B:)
Via nose and windpipe
though his nose which has many columns for air to pass through
Mucus in your nose with air trying to move pass it
Nasal sounds are sounds made using the nose, where air is allowed to pass through the nose when talking for example.
To fight off air resistance and go faster. If the airplane had a flat nose, (like your palm) the air resistance would affect the nose and make the plane slower, while a pointy nose allows the air resistance to pass by therefore making the plane go faster.
Air or CO2 must pass through the respiratory system, specifically the lungs. During exhalation, these gases move out of the lungs and are expelled from the body through the nose or mouth.
The nose serves as the primary entrance for air into the respiratory system. It warms, filters, and humidifies air as it passes through to the lungs. Additionally, the nose contains specialized cells that detect smells and help with the sense of taste.
We get the speed by aero dynamics by if the vehicle or vessel is "Streamlined" or its shape lets air pass down it quickly e.g an aero plane has a a curved nose just to let the air pass quickly instead of a block shape to block out the air!!
it is the only suitable shape to travel at more than mach speed.
The windpipe is also known as the trachea. The function of the windpipe is to provide a clear path for air from the nose and mouth to pass to and from the bronchial tubes.
The air that enters the nose is the same that is found in our lower atmosphere: roughly 78% nitrogen, 21% oxygen, and 1% other. Once the air passes through the nostrils, some of the larger particles like dust and sand are filtered out before it gets to our lungs.
