Particulates
Microscopic particles of ash and dust in the air that can cause health problems are called particulate matter (PM). These particles can vary in size, with PM2.5 (particles with a diameter of 2.5 micrometers or smaller) being particularly concerning due to their ability to penetrate deep into the lungs and enter the bloodstream. Exposure to particulate matter is associated with respiratory and cardiovascular issues, as well as other health complications.
it is called the avoile
Because they stop microscopic particles lile pollen and dust getting into your lungs.
The microscopic hairs in the airway that help keep dirt and other particles out of the lungs are called cilia. These tiny, hair-like structures line the respiratory tract and work in tandem with mucus to trap and move foreign particles and pathogens upward toward the throat, where they can be swallowed or expelled. This mechanism is crucial for maintaining respiratory health by preventing the accumulation of harmful substances in the lungs.
Oxygen must enter our blood and Carbon Dioxide must leave the blood through our lungs. They do so by diffusion between the cappillaries.
Cilia are the microscopic hairlike projections found in the cells lining most of the respiratory tract. They help to sweep mucus and trapped particles out of the airways to protect the lungs from infections and irritants.
Aleoli
Because you suck in air through your mouth or nose and it goes into your lungs... it's called breathing =)
Dust particles enter your lungs, and clog it up, leading to breathing/respiratory problems.
Pine tar it has many cancerogenic substances.You must use them carefully and not for a long periods.
Mucus enters the lungs through tiny hair-like structures called cilia that line the respiratory tract. It helps to trap and remove harmful particles, such as bacteria and dust, from the air we breathe. This helps to protect the lungs from infections and maintain respiratory health.
They can get into your lungs.
