mucus
Mucus in the nose helps trap particles entering the respiratory system. The hairs/cilia of the respiratory system also filter incoming air.
fresh clean air
the trachea
Nose hairs.
It helps us to breathe more comfortable.
The nose is the first cleaned and moistened warm part of the respiratory system. The nose acts as a filter for air to get to the lower respiratory system.
Cilia are the tiny hairs that sweep dust and dirt out of the respiratory system.
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.
The respiratory system supplies the body with O2 (respiration). This system also disposes of CO2 (ventilation). The respiratory system houses the olfactory receptors. Gas exchange between blood and air in the alveoli(external respiration)Gas exchange between the blood and cellular tissue (internal respiration).
