The gravity traps everythings on a planet.
because of the sand particles
nose hairs
Mucus is the secretion produced by the respiratory system that traps dust and other inhaled foreign particles. It helps to protect the lungs by capturing these particles before they can reach deeper into the respiratory tract.
Venus
mucus
Venus is the planet that traps the most heat due to its thick atmosphere composed mainly of carbon dioxide. This greenhouse effect causes extremely high temperatures on the planet's surface, making it the hottest planet in our solar system.
The Greenhouse effect...
Cilia acts like a filter. It traps dirt particles that we inhale and moves these particles out of the body.
Air particles can be trapped by various materials such as filters (like in HVAC systems), nets (used in air filtration systems), and physical barriers (like in a sealed container). These traps prevent the movement of air particles by obstructing their path, allowing cleaner air to pass through.
Saturn
The secretion that traps dust and other inhaled particles is mucus, produced by mucus-producing cells lining the respiratory tract. This mucus helps to capture and remove particles from the air we breathe, preventing them from reaching deeper into the lungs where they could cause damage or inflammation.
A greenhouse effect traps heat that would otherwise escape out to space, so it keeps the planet warm.
