Structure of the Human Organism.

The human body consists of fuids and
solids, changing constantly from one into
the other. Their proportion to eacn other
varies in different individuals and at diff
ferent periods of life. In youth, the fluids
are more abundant than in advanced age.
The liquids contain, as it were, the whole
body in its elementary particles, which
by organic attraction are formed into the
different solid parts of the system. They
exist in different degrees of solidity as
their varied uses require. The simplest
form of organized animal substance is
membrane or tissue, composed of fbres
interviewer like network. All our organs
| are formed by tissues which are different
and adapted to their uses.
The mttc,ts membranes line all the
cavities which communicate with the air,
as the mouth, nostrls, intestinal canal,
lungs, etc, and are covered with minute
cells which secrete yised fluid called
mucus, TO protect the inner surfaces or
| cavities from contact with the air. When
cdtarrh becomes local from any cause what
ever, these membranes suffer according
| to the severity of the disease. The serous
membranes line cavities which do not
| communicate with the air, as the skull,
| chest, abdomen, etc. A seroas membrane
| is a sheath sac with one layer opposed to
the wall of the cavity, and the other
| folded around the contents of the cavity,
which contents are outside the sac. A
serous fluid is secreted between the sides
/ of the sac to keep them moist aud inovea
BILE. Areoidr or cellular tissue is extensively
distributed throughout the system, and is
useful in enveioping organs and parts of
organs, especially where considerable
degree of motion is required, which mo-
tion it never impedes, being abundantly
/ supplied with fluid. The ddipose tissue
| forms distinct bags or cells filled with fat
and is principally located beneath the
| skin and around the heart and kidneys.
| The cRdneous membranes form the outside
| covering of the body, called the skin, and
is similar in strueture-although harder
to the mucous membrane, of which it
forms the external continuation. 1t Sc
cretes constantly y fluid which is called
perspiration if it appears in large quanti-
ties; it exists mostly. however, in an
imperceptibie vapor, which, as it were
constitutes the atmosphere of the body
The fbrous tissue forms thin, dense
/ strong membrane. and is found where
strong protection is needed, as in the
| lining of the internal surface of the skull
around the bones aud at the end of thu
muscles; here it constitutes the so-callee
lgdnaeats and tendons The cariilaginou
} tissue covers the ends of the bones whert
they concur in forming 8 joint and is OF
} that account firm, smooth and elastic. Th'
osseoas tissue, which composes the bones
varies in different periods of life as regards
solidity and density. These also become
! affected in dry anu cdnceroas catarrh.
) The muscular tissue consists of manl
filaments, which united form fibres, eaci
of which is enclosed in q fine layer 0
areolar tissue, called sarcolemma. Muscles
are composed OF bundles of these fibres
The nerrous tissue is composed of tw,
distinct substances, one gray and vascular
the other white and fbrous. The gre,
forms the external part of the brain ant
: the internal part of the spinal cord, Will,
the nerves are composed of the white
inclosed in sheath called ne,rIemma.
The elements of the human body ar,
. organic or elementary products of tn,
system itself; and inorganic or chemical
, The organic elements are: Albumen
: fibrin, gelatin, mucus and osmazome, etc
1 The inorganic elements are Metali
!. | and non-metalic. The metallic substance
are such as potash, soda, lime, Haagnesia
/. alum, selix, manganese, copper and iron
= The non-metalic substances are such a
! oxygen, hydrogen, caTbona, nitrogen
phosphor, sulphur. prussic acid, etc,
: deficiency ~ eyaess of these elements i
: the organs i. ,sodpces disease to th
= extent of lack or over supply. When tn
= unballance reaches certain degree, dealt
!. is the inevitable result. How necessar
! then that We thoroughly understand on
i own organisms.
