Study Notes
Blood Composition and Function
- Blood is crucial for transporting oxygen and nutrients to body tissues, and removing metabolic waste like carbon dioxide.
- Blood's composition includes plasma (water, proteins, and dissolved compounds) and blood cells.
- Plasma differs from serum as it contains clotting factors (fibrinogen).
Haematopoietic System Overview
- The haematopoietic system encompasses all blood cells and their precursors.
- Blood cells include erythrocytes (red blood cells), leukocytes (white blood cells), and thrombocytes (platelets).
- These cells originate from a common progenitor: the hematopoietic stem cell.
- They have distinct developmental stages and locations (blood circulation or specialized development sites).
- Each cell type plays a unique role maintaining bodily equilibrium (homeostasis).
Erythrocytes (Red Blood Cells)
- Erythrocytes transport oxygen and nutrients.
Leukocytes (White Blood Cells)
- Leukocytes are involved in immune defenses.
Thrombocytes (Platelets)
- Platelets play vital roles in blood clotting (hemostasis) and thrombosis.
Haematopoiesis (Blood Cell Production)
- Blood cell production (hematopoiesis) involves several key processes:
- Cell proliferation
- Differentiation from stem cells to mature forms
- Morphological change specific to each cell type
- Functional maturation
- Cell death.
