1. The Blood,Lymphatic
and Immune Systems

2. ANATOMY&
PHYISIOLOGYOF
BLOOD
THREE TYPES OF BLOOD CELLS:
• Erythrocytes (red blood cells)
• Leukocytes (white blood cells)
• Platelets
As a group, these cells are referred to as
"formed elements." Every human has an
average of five liters of blood flowing
through them!!

3. BLOODTYPING
▪ Everyone has a different blood type due to
antigens on red blood cells (Type A,B, AB,O-
or O+)
▪ The ABO blood system determines what blood
type an individual has.Each red blood cell has
a "marker"
▪ When receiving blood transfusions,
individuals can only receive blood types
matching their own.
▪ RH Factor is also a blood marker.An individual
with RH+ markers can only receive RH+ blood
and vice versa.

4. COMMON BLOOD REALTEDTERMS
▪ Hematology: Study of diseases/conditions of the blood
▪ Erythrocytic: Pertaining to red blood cell
▪ Hematic: Pertaining to blood
▪ Hematoma:Collection of broken blood vessels under the skin; a
bruise
▪ Leukocytic: Pertaining to white blood cell
▪ Thrombocytic: Pertaining to a clotting cell: a platelet
▪ Thrombotic: Pertaining to a clot

5. LYMPHATIC &
IMMUNE SYSTEMS
These systems work together to fight
against foreign bodies/ substances &
disease in the body.
The organs that make up these
systems are:
• Lymph nodes
•LymphaticVessels
•Spleen
•Thymus Gland
•Tonsils

6. LYMPHATIC
VESSELS
• These vessels run an
extensive network
throughout the body.
However, they do not run in
a loop like the circulatory
system
• These vessels run one way
and dumb excess fluids
(lymph) back into the
thoracic duct.

7. LYMPH
NODES
▪ Also known as lymph glands,these
store lymphocytes and antibodies
which remove pathogens and cell
debris out of the lymphatic vessels to
allow lymph safe passage back to the
thoracic cavity.
▪ Lymph nodes also aid in trapping
and destroying cancerous tumors.

10. THYMUS GLAND
• The thymus gland is vital in proper
development of the immune system.
• It aides in development of antibodies
and immune system function.
• This organ makes thymosin,
which changes lymphocytes to T
lymphocytes (T cells)

11. IMMUNITY
• Immunity is the bodies ability to fight against pathogens (bacteria, viruses, etc.)
• Immunity comes in two forms: natural & acquired
• Natural immunity is self explanatory; it's ones innate disease fighting ability. This
means ones ability to fight disease without medicine or intervention.
• Acquired immunity is ones ability to fight disease with outside factors. (EX taking
medicine, being exposed to chicken pox once)
