What is your Immune System?

The immune system is a system
of many biological structures
and processes within an
organism that protects against
disease. To function properly,
an immune system must detect
a wide variety of agents, known
as pathogens, from viruses to
parasitic worms, and distinguish
them from the organism's own
healthy tissue.
What is it made up of?

The thymus

The spleen

The lymph system

Bone marrow

The white blood cells

Antibodies

The complement system

Hormones

Overall these are all Tissues organs and cells,
White Blood Cells

White blood cells (WBCs), also
called leukocytes or leucocytes,
are the cells of the immune system
that are involved in protecting the
body against both infectious
disease and foreign invaders.
In normal adult bodies there are
4,000 to 10,000 (average 7,000) white
blood cells per microliter of blood. If
the number of white blood cells in
your blood increases, it is a sign of an
infection somewhere in the body.
Red Blood Cells

Red blood cells play an important role
in your health by carrying fresh oxygen
throughout the body.

Red blood cells are round with a
flattish, indented center, like
doughnuts without a hole.
Your healthcare provider can check
on the size, shape, and health of your
red blood cells using tests, such as the
complete blood count screening.

Adult humans have roughly 20–30 ×
1012 (20–30 trillion) red blood cells at
any given time, comprising
approximately one quarter of the total
human body cell number
The Four Main Types of Germs

Germs are found all over the
world, in all kinds of places.
The four major types of
germs are: bacteria, viruses,
fungi, and protozoa. They
can invade plants, animals,
and people, and sometimes
they make us sick.
Scientific Names*
Lymphatic System

The lymphatic system is part
of the circulatory system
and a vital part of the
immune system, comprising
a network of lymphatic
vessels that carry a clear
fluid called lymph
directionally towards the
heart.
What does it do?

The lymphatic system is a
network of tissues and organs
that help rid the body of
toxins, waste and other
unwanted materials. The
primary function of the
lymphatic system is to
transport lymph, a fluid
containing infection-fighting
white blood cells, throughout
the body.
*Cycle of Lymphatic system
Lymph Node Cancer

Lymphoma is a group of blood
cell tumors that develop from
lymphocytes. The name often
refers to just the cancerous
ones rather than all such
tumors. Signs and symptoms
may include enlarged lymph
nodes, fever, drenching
sweats, unintended weight
loss, itching, and feeling tired.
The enlarged lymph nodes are
usually painless.
*Most commonly on right side of neck
Functions of Tonsils

A main function of tonsils is to trap
germs (bacteria and viruses) which
you may breathe in. Proteins called
antibodies produced by the immune
cells in the tonsils help to kill germs
and help to prevent throat and lung
infections. You can normally see your
tonsils by opening your mouth wide
and looking in a mirror.
Tonsillitis Procedure

Tonsillitis is inflammation of the
tonsils most commonly caused
by viral or bacterial infection.
Symptoms may include sore
throat and fever. When caused
by a bacterium belonging to the
group A streptococcus, it is
typically referred to as strep
throat. The overwhelming
majority of people recover
completely, with or without
medication.
*In 40% of cases people get your tonsils
removed.
Antigen – Antibody reaction

Antigen – substance that body sees as foreign.

Examples – viruses , bacteria toxin, transplant tissue

Antigen antibody reaction – a.k.a immune reaction. Binds antigens
to antibodies. Labels potentially dangerous antigen so it can be
destroyed
