The document summarizes the key components and functions of blood and the lymphatic system. It discusses how blood transports nutrients, gases, and waste, and is composed of plasma, red blood cells, white blood cells, and platelets. It then explains the production of blood cells, the roles of each blood component, blood types, and the lymphatic system's role in immunity and defense.

1. Blood and
Lymphatics

2. Blood
• A critical agent of
transportation of nutrition,
gases, and waste to all parts
of the body.
• Parts attach to red blood
cells or dissolve in plasma.
• White blood cells fight
infection and disease.
• Platelets initiate blood
clotting.

3. Blood Components
• Blood is a mixture of
• Plasma
• Formed Elements
• Erythrocytes= Red
Blood Cells
• Leukocytes= White
Blood Cells
• Platelets

4. Production
• Hematopoiesis= blood cell
production by red bone marrow
• Red bone marrow most abundant
in children
• Adults have more yellow marrow
than red

5. Plasma
• 55% of adult whole blood supply
• 90-92% is water
• 8-10% is dissolved substances:
• Plasma proteins
• albumin-transport fatty
substances
• Globulin- type of antibody
• Fibrinogen- blood clotting
protein
• Ca, K, Na, glucose, amino acids,
and fats are also transported via
plasma

6. Erythrocytes
• Red Blood Cell
• Not a true cell- no nucleus
• Hemoglobin creates red color
• this is what picks up oxygen from
lungs to deliver to tissue.
• Lifespan of 120 days
• Spleen removes worn-out/damaged
RBC

7. Leukocytes
• White Blood Cells
• True Cell
• Provides protection against
pathogens like bacteria and
viruses

8. 5 Types of Leukocytes
• Granulocytes- granules in
cytoplasm
• Basophiles- histamine
and heparin release
• Eosinophils- destroys
parasites- high in allergic
reactions
• Neutrophil- phagocytize
foreign and damaged
cells
• Agranulocytes- no granules
• Monocyte- phagocytize
foreign and damaged
cells
• Lymphocytes- several
roles in immune response

9. Platelets
• Modern term thrombocyte= smallest of
all blood elements
• Not whole cells but formed when
cytoplasm of larger cell shatters into
fragments.
• Critical for blood clotting- hemostasis
• Agglutinate- clump together when
blood vessel is cut

10. Blood Types
• Blood differs because of
presence of antigens or
markers on RBC
• Type:
• A
• B
• AB= universal recipient
• O= universal donor

11. Rh- Factor
• If present, then Rh+
(Type A+, B+, AB+, O+)
• Not present then Rh-
(A-, B-, AB-, O-)
• Rh + can have blood
transfusion for positive
and negative Rh
• Rh- can only have
transfusion for negative
Rh-

12. Lymphatics
• System composed of:
• Lymphatic Vessels
• Lymph Nodes
• Spleen
• Thymus
• Tonsils
• Fluid in system is called lymph
• Serves at body primary defense system

13. Network
• Lymphatic Vessels- network of ducts, one
way system
• Lymph Nodes- small organs/ glands that acts
like a filter to remove pathogens and debris
• Tonsils- each side if throat. Lots of leukocytes.
Filters to protect body digestive and
respiratory.
• Spleen- filters blood
• Thymus Gland- development of immune
system

14. Immunity
• Body ability to defend itself from
pathogens
• Natural immunity/ innate immunity
• What the body already is equipped
with- ie macrophage
• No exposure to disease or pathogen
• Acquired immunity
• Body response to specific pathogen
