Nasal cavity in the upper respiratory tract.
Most breathing in healthy humans occurs through the nose. As air enters the nasal cavity, it is filtered of large debris by hairs lining the inside of the nose, and then further filtered through the nasal conchae, an area of folded, moist tissues; this also warms the air to near body temperature when it is cold.
The air first enters into the nasal cavity (or mouth) then to the pharynx. Air is warmed by the nasal passages. From there, it passes through the trachea, then to the main bronchi (2, plural is bronchi; 1 is bronchus), and begins its descent into numerous bronchioles in the lungs. Within the lungs, the structures look like an upside down tree, wider at the top (the bronchi, which is like a split trunk of a tree), and getting increasingly narrower in the bronchioles (similar to branches on a tree being wider then getting narrower as the branches reach upward on a tree). At the ends of each bronchiole, there are clumps of aveoli which look like a clump of grapes. The aveloi round balls (just one is an aveolus) have a thin membrane which has many small blood vessels over and around each one. Here, the air we breathe passes into the bloodstream as oxygen. At the same time, carbon dioxide is released from the bloodstream to the aveloi, which expel it into the bronchioles, up though the lungs to the main bronchi, up the trachea, and back up to and out either the nose or the mouth.
Warm and wet air does move through both mouth and nose. You can shut your mouth and air will just come from the nose.
air is filtered, warmed, and moistened.
warmed, moistened and cleaned by the nose and mouth
In the lower respiratory system, air that has been filtered of pathogens and warmed in the upper respiratory tract is transported to the lungs. There, oxygen will be pulled from the inhaled air and deposited into the bloodstream, while carbon dioxide pulled from the bloodstream is released back into the lungs to be expelled from the body upon exhaling. This exchange of gases is the primary function of the respiratory system.
Inhaled air is warmed and moistened in the nasopharynx and oropharynx.
As air enters the respiratory system through the nose, it is warmed, filtered, and moistened. These changes increase the efficiency of gas exchange in the lungs, and protect the lungs from particulates.
As air passes along the upper respiratory tract, it is warmed, moistened and filtered. The mucous membranes and cilia help these processes.
1) Nasal passage- This is your nose. Air enters here and is moistened, warmed, and cleaned. 2) Trachea- Your windpipe. It is held open by rings made of cartilage. Air passes through here. 3) Bronchi- Two tubes that branch from your Trachea. They each lead to a lung. 4) Bronchioles- Smaller branches coming from the Bronchi. 5) Lungs- An organ containing alveoli. 6) Alveoli- The smallest working part of the respiratory system, and the respiratory surface. They are moist and one-cell thick and are surrounded by capillaries for call exchange. That's about it :)
Hydrate input air, filter out large particles. and reabsorb moisture from the exhaled breath.
so that it doesnt harm the delicate tissue inside the lungs. the same as humans
Nasal cavity in the upper respiratory tract.
The nose is the organ of smell, part of the of respiratory system, and it adds nasal sounds to the voice. Air passes through a lining of stiff hairs that catch dust particles and small insects before entering the nasal passages where it is warmed and moisturized before passing into the respiratory system on its way to the lungs. The olfactory nerve (nerve of smell), is located in the soft mucous membrane inside the nose.
The inhaled air 'swirls' around the conchaemoistens via the mucus secreted by the goblet cells and drainage from the nasolacrimal ducts; cleans by the mucus trapping dust particles and the cilia moving the mucus and trapped dust particles toward the pharynx
