What is an Example of filtration in the human body?

Answer 1

air is filtered through the cilia and mucus of the nasal passages and those of the trachea (throat). before air even enters the body, it is filtered by plants which use photosynthesis to turn carbon dioxide into oxygen

Answer 2

Filtration in the human body is a process through which nutrients are filtered. Some of the places where filtration takes place include the small intestines, kidneys and red blood cells among others.

Answer 3

through tiny sacks in the lungs called alveoli, the ribs expand out causing air to be pulled in. the air enters the lungs and waste is carried from the blood to the air in the lungs and oxygen is exchanged from the air into the alveoli to be absorbed into the blood

Answer 4

If you breathe through your mouth then many are absorbed into the moisture in your mouth (saliva).

It is much better to breathe through your nose, however, as it contains both mucus, which is much better at absorbing particles and small hairs which act as a kind of net for them, it also warms the air up much more.

Answer 5

Your respiratory tract has many thousands of glands that produce mucous. This sticky material picks up dust, dirt, smoke, bacteria and other tiny things you inhale. Also lining the tract are thousands of cells which have hair-like cilia which move the mucous up to your throat and you swallow it. The acids in the stomach digest the materials. If these hairs are destroyed by smoking or by another manner, you can not move the mucous and this problem is called COPD.

Answer 6

filtration occurs in the kidneys and helps filter out harmful waste
