Trachea

Epiglottis

Cilia are like little hairs. They help to collect things that should not be in the lungs. They may catch some bacteria and send it elsewhere to be fought off with white blood cells. Your nose has cilia to prevent most germs from entering the body. It is just another precation the body takes so it does not have to work as hard to defend itself later.

True

The sphere of the eye has the lowest internal stress energy of geometric structure and even if a vitrectomy has been performed removing all the fluid the eye maintains most of it's original shape

yes

Tracheorrhagia is bleeding from the trachea. Tracheitis is inflammation of the trachea.

It is the epiglottis.

The right and left main bronchus (which supply air to the right and left lung).

The trachea, or windpipe, is a tube that connects the pharynx or larynx to the lungs, allowing the passage of air.

Because there is a flap in your throat that covers the appropriate passage at the appropriate time.

Ex: When you are eating, the flap usually covers the trachea.

However, if you are laughing while eating, the flap can get very confused and may cover the esophagus instead of the trachea, allowing food to go down it.

I hope this helped~

Beating ciliated epithelial cells

The lungs rely totally on positive pressurized steady airflow and high dynamic air pressure values of sucked in inspired air to inflate them, the air must be very humid and warm - or the fine narrow tubes (the bronchioles and the alveoli) might not get inflated properly, or not get inflated at all at the most remote ends of the lungs. If proper lung inflation is denied chronically - this can result after some years into a life threatening lung disease called Emphysema. Humidification is also crucial for sustaining the integrity and survival of the cilia blanket's hairy layer, which covers the entire respiratory tracts, including the nose.

Yes. It also prevents liquids from entering the trachea when one swallows.

trachea has cartilage rings which it open all the time

Yes. Although a person without an esophagus cannot swallow food, prepared meals can be introduced into the stomach to provide nutrition. In most cases, doctors will attempt to fashion a new esophagus to connect the mouth to the stomach. In this procedure, the complex working of the epiglottis is the most difficult to replace.

The pharynx is the space that contains the larynx, which is known as the voice box, which contain the vocal cords.

Pseudostratified columnar epithelium (ciliated form)

The epiglottis protects the trachea from food.

After the trachea, air goes into the primary bronchi, then interpulmonary bronchi, then bronchioles, then terminal bronchioles, then into the alveoli.
