Hematologic and Lymphatic Systems

Anatomy and Physiology Review

• Heart pumps 5 to 6 liters of blood per minute through adult circulatory system

• Lymphatic system– Separate vessel system with two main

functions:• Transport excess fluid from interstitial spaces to

circulatory system• Protect body from infections

Function of Blood

• Transport O2, CO2, water electrolytes, hormones and enzymes

• Heat to regulate body temperature

• Immune bodies and antibodies to help prevent disease and infection

• To provide clotting of blood in case of injury

• Prevent clot formation in blood vessels

Formed Elements

• Erythrocyte

• Leukocyte

• Thromobocyte

What is the action of STEM CELLS?

Red Blood Cells…

• Formed in red bone marrow

• Needs Vitamin B12, Intrinsic Factor, Iron, Folic Acid for manufacture

• Erythropoesis

• Carries O2 on the Hgb (12 – 16)

• Carries CO2 to lung for elimination

• Life span 120 days

Erythrocyte

Erythropoetin

Hemoglobin

• Millions of Hgb molecules per RBC

• Synthesis dependent on iron

• Carries O2 to cells of body

Hematocrit (Hct)

White Blood Cells…

• MULTIPLE TYPES– GRANULOCYTES

• MADE IN BONE MARROW• FIGHT INFECTION

– AGRANULOCYTES• MADE IN LYMPH• KEEP US HEALTHY

– ETC.

Leukocytes

Thrombocytes

Plasma

• Liquid part of blood; 90% water with 10% dissolved substances (proteins)

• Regulates blood volume

• Provides nutrition of body cells

• Function in clotting of blood

• Circulates antibodies
