immune system
- It is the body's defence
system, it protects us
from bacterias and
diseases and fight for
our bodies to get rid
of them
- Organs
- Lymphoid
organs
- WHICH
INCLUDE
- Thymus: gland
between the lungs and
below the neck.
- Produce Lymphocycles
- Produce Lymphocycles
- Spleen: Theorgan
that filters the blood.
It is in the abdomen
on the left.
- Bone marrow: in the center
of the bones, it also
produces red blood cells
- Lymph nodes: small glands located
throughout the body, linked by lymphatic
vessels.
- also appendix, tonsils, and other
tissues in different organs
- Thymus: gland
between the lungs and
below the neck.
- WHICH
INCLUDE
- Lymphoid
organs
- White blood
cells
- Are stored in the
lymphoid organs
- Are stored in the
lymphoid organs
- Active and passive immunity
- Active
- The body creates
antibodies which
prevent more attacks
- The body creates
antibodies which
prevent more attacks
- Passive
- The antibodies are
temporary, the antibodies
are in vaccines
- The antibodies are
temporary, the antibodies

- Active
- LINES OF DEFENSES
- THERE ARE 3
- 1
- Skin, saliva, mucus, cilia and stomach acid
- Skin: The Epidermia forms a barrier.
We shed about 40-50 dead skin cells
daily.
- Saliva: It has chemicals
that break down bacteria
bu kost bacteria survive
- Mucus and
cilia:protects the
respiratory system
by trapping
bacteria
- Stomach acid:
bacteria is
broken down
with the acid
- Skin: The Epidermia forms a barrier.
We shed about 40-50 dead skin cells
daily.
- Skin, saliva, mucus, cilia and stomach acid
- 2
- Inflamatory response, interferon and white blood cells
- Inflamatory reaponse: the
hurt cells release chemicals
and beggin inflamating the
areas
- Interferon: the chemicals
which interfere with the
infection process
- White blood cells: Attack when there is an
invader in the body. There is the T-Cells
and there is the Phagocitosis
- T-Cells attack the infected cells
- In phagocitosis the neutrophils eat the invader
by engulfing it, then they break it down.
- T-Cells attack the infected cells
- Inflamatory reaponse: the
hurt cells release chemicals
and beggin inflamating the
areas
- Inflamatory response, interferon and white blood cells
- 3
- The antibodies
- Most bacteria dont get here
- Proteins that latch into, damage,
clump or slow the invaders
- Most bacteria dont get here
- The antibodies
