Well my EDUCATIONAL guess its Larnx!
trachea
The trachea is the passage way for air to travel from the larynx to the lungs.
Pharynx
The function of the trachea is the same in all terrestrial vertebrates. It provides an airway from the mouth to the bronchi.
The passage between the nose that i fink u r looking the answer is the trachea which leads the air to the lungs
The larynx is situated just above the trachea which are tubes which carry air and oxygen to the lungs. Inflammation causes swelling of the tissues which can block the entrance to the trachea and air entry to the lungs
Bronchus principalis=>bronchi lobares=>bronchus segmentalis=>bronchiolus terminalis=> bronchiolus respiratorius=>ductulus alveolaris=>sacculus alveolaris=> alveolus i hope that you don't mind latina terminology.
The diapragm is most important to the respiratory process. Your diaphragm pulls down when you inhale, opening your lungs up and letting air in. Your trachea is what brings athe air from your nose to your lungs. Nose, pharynx, larynx, trachea, bronchi, lungs, and diapragm are all involved.
You need a larynx because it contains the vocal cords and the epiglottis. You need the vocal cords so you can talk and sing, and you need the epiglottis so you can swallow food or liquid without it going into your lungs, or choking to death.
A crushed or severly bruised larynx is a critical injury, although it is not 100% lethal. The problem is the collapse of the process, and/or the subsequent swelling shutting down the airway causing asphyxia. Note that a victim of this sort of injury who can breathe immediately after the injury, may have more trouble later, as swelling increases. If you suspect a crushed larynx, transport. That way, if things go south, you'll be in a place equipped for surgical intervention.
What is the passage way into the cell?
Well, the next region that air passes is consequently the nasal cavity. But beyond that, it flows through the nasal and paranasal sinuses, and eventually makes it way down to the larynx and pharynx.
the passage way of blood is the vessel
