Closets in Human Uranium Must
Be Kept Ventilated.
Nose Serves as Radiatcr-Postion of
the Eustachian Tube-Open Spaces
Receive Warmed and Moistened
Air to Insure Health.

Our heads are full of holes that must
be ventilated If we are to remain in
good health. Most people think the air
they inhale goes only to their lungs.
and that its one use Is to purify their
blood. The air has another and just
as important function-the aeration
of the hidden cupboards and closets
of the head.
The nose is a sort of radiator,
formed of twisted tubes, in which the
inhaled air is warmed and moistened.
When you exhale vigorously the air Is
forced up into the recess back of the
nose. This is called the naso-pharynx.
From this many tubes open upward
and backward, each leading to one or
more of the closets in the head.
The best known of these is the Eus
tachian tube, which runs from the
back of the pharynx to the middle ear.
The middle ear is behind the drum. In
it are situated the little bones that
connect the drum with the nervous ap-
paratus of the inner ear In the rear
walls of the middle ear is large ir-
regular opening leading to the mas
told antrum, a large cavity in the up
per part of the mastoid bone, behind
the ear. This communicates again
with net work of irregular cavities
that make a sponge-like structure of
the interior of the mastoid process.
Air passes through the Eustachian
tubes into the middle ear and on into
the hollows of the mastoid bone. In
lection also takes the same route, and
this is how nasal catarrh may cause
serious attack of mastoiditis that
can be cured only by terrible and
often fatal operation that begins with
chopping open the mastoid bone with
chisel and mallet.
Over the eyebrows, toward the mid
frontal bone are the frontal sinuses,
irregular cavities which are connected
with the middle of the nose by tube
| called the infundibulum.
Behind these again are the cells Of
the ethmoid bone, called the anterior
open also into the nose by two differ
ent tubes. The anterior sinuses open
also into another cavity called the an
trum of Highmore.
The antrum is situated in the cheek,
Immediately over the hicuspid and mo
| lar teeth It's size varies in different
| individuals and it is not always the
same size on each side Of the face,
1t opens directly into the pharynx. Its
floor is the alveolar process of the
upper teeth and it's roof is the floor OF
the eye cavity.
Farther back in the head than any
| of these except the mastoid are the
sphenoidal sinuses. They also open
| into the pharynx by two round holes
and they sometimes communicate
with the posterior ethmoid cells or
sinuses.
Many of these sinuses communicate
with the posterior ethmoid cells or SIN
uses.
Most of these sinuses communicate
with labyrinths or smaller holes IN
the bones about them. Many Of them
do not exist at birth tInd only begin
to develop about the seventh year,
growing larger until the age of about
twenty.
Vigorous exhalation drives the air
that has been warmed and moistened
in the lungs into all of these hidden
cavities in the head. They are there
to contain air, and this air must not
become stagnated. If the head be
stopped up by catarrh some of them
are sure to- become involved. The re-
suit is headache, earache and some
times insanity.
Therefore in breathing it is as i'm
portant to blow air forcibly up into
the upper pharynx as 1t is to draw it
down into the lungs.
