It helps us to breathe more comfortable.
fresh clean air
mucus
Mucus in the nose helps trap particles entering the respiratory system. The hairs/cilia of the respiratory system also filter incoming air.
The respiratory system is there so you can breath air in and exhale out. When you breath in your breathing in air, but what your really breathing out when you exhale is carbon dioxide. So what your respiratory system does is it takes in clean air and disposes the carbon dioxide from your lungs.
The physiological function of the respiratory system is helping our body breathe clean air (oxygen) and breathing out carbon dioxide.
the cilia filtrate the air going into the system
This is mostly the respiratory system though it does include parts of the cardiovascular system.The respiratory system; more specifically, it happens in the alveoli of the lungs.
Air sacs are part of the respiratory system

the respiratory system
The respiratory system does not contain any structure that filters air. The trachea and bronchus are lined with a mucous membrane that helps trap debris and carry it out of the body, but this is not a filtration system.
The respiratory system is the organ system that moves air into and out of your body.
