3. Introduction
• Welcome and introduce the topic: Blood Composition: A
Comprehensive Overview.
• Briefly explain the importance of understanding the composition
of blood.
• Highlight the role of blood in maintaining overall health and
bodily functions.
4. Functions Of Blood
• The primary functions of blood:
• Transportation: Carries oxygen, nutrients, hormones, and waste
products throughout the body.
• Regulation: Maintains body temperature, pH balance, and
electrolyte levels.
• Protection: Helps in clotting, immune response, and preventing
infections.
5. Components Of Blood
• Blood consists of two main components: plasma and formed elements.
• Plasma: The liquid portion of blood that makes up about 55% of total blood
volume.
• Composed of water, proteins, hormones, electrolytes, and waste products.
• Formed Elements: The cellular components of blood that make up about 45%
of total blood volume.
• Red blood cells (erythrocytes), white blood cells (leukocytes), and platelets
(thrombocytes).
6. Plasma
• Plasma composition:
• Water: Makes up the majority of plasma volume.
• Proteins: Albumin, globulins, and fibrinogen play various roles in blood
function.
• Hormones: Transported by plasma to target tissues.
• Electrolytes: Help maintain osmotic pressure and pH balance.
• Waste products: Urea, creatinine, and bilirubin are carried by plasma for
elimination.
7. Red Blood Cells
• Red Blood Cells (Erythrocytes)
• Characteristics and functions of red blood cells:
• Structure: Biconcave disc-shaped cells without a nucleus.
• Hemoglobin: Protein that carries oxygen and carbon dioxide.
• Function: Transport oxygen from the lungs to body tissues and
remove carbon dioxide.

9. White Blood Cells
• White Blood Cells (Leukocytes)- Explain the types and functions
of white blood cells:
• Granulocytes: Neutrophils, eosinophils, and basophils. Involved in
immune response and defense against infections.
• Agranulocytes: Lymphocytes and monocytes. Play a role in
immune response and phagocytosis.
10. Platelets
• Platelets (Thrombocytes)
• Characteristics and functions
of platelets:
Structure: Small cell fragments
without a nucleus.
Function: Essential for blood clotting (hemostasis) to prevent excessive
bleeding.
11. Hematopoiesis
• Hematopoiesis
• Process of hematopoiesis:
• Occurs in the bone marrow.
• Stem cells differentiate into various blood cell types.
• Controlled by growth factors and hormones.
12. Blood Groups &Rh Factor
• Blood Groups and Rh Factor
• Introduce the concept of blood groups and the Rh factor:
• ABO blood group system:
• A, B, AB, and O blood types.
• Rh factor: Refers to the presence or absence of the Rh antigen
on red blood cells.
13. Blood Disorders
• Blood Disorders
• Provide an overview of common blood disorders:
• Anemia: Decreased red blood cell count or hemoglobin levels.
• Leukemia: Cancer of the blood-forming cells in the bone marrow.
• Thrombocytopenia: Low platelet count, leading to increased bleeding
risk.
14. Conclusion
• Summarize the key points discussed in the presentation.
• Emphasize the vital role blood composition plays in maintaining
overall health.
• Encourage further exploration of the topic and address.
