Study Notes
Blood Cells and Their Functions
- Red blood cells (RBCs) are responsible for carrying oxygen to the body's tissues.
- Platelets are responsible for blood clotting.
- White blood cells (WBCs) are primarily involved in the body's immune response.
Blood Composition
- Plasma consists of water, electrolytes, and proteins, and serves as a medium for blood cells to circulate in.
- Plasma makes up the remaining 55% of the volume of blood tissue, apart from the three major types of blood cells.
Platelet Function
- The primary function of platelets is to release thread-like fibers to form blood clots, a process called hemostasis.
Red Blood Cells
- RBCs carry oxygen to the body's tissues through a process called oxygenation.
- Hemoglobin, an iron-containing protein, gives RBCs their color and facilitates transportation of oxygen from the lungs to tissues.
- RBCs are formed in a process known as erythropoiesis from hematopoietic stem cells.
- The approximate lifespan of RBCs is 120 days.
- The normal count of RBCs per cubic millimeter (cu.mm) in adults is approximately 5 million.
White Blood Cells
- WBCs, or leukocytes, are involved in phagocytosis to defend the body against pathogens.
- WBCs derive from hematopoietic stem cells.
- The term for the number of WBCs in circulation being commonly increased in the incidence of infection is leukocytosis.
- The condition called when there are too few WBCs in the body is leukopenia.
Blood Clotting
- Platelets release thread-like fibers to form blood clots, a process called hemostasis.
Blood Tests
- The term for the rate at which RBCs sink to the bottom when placed in a vertical column after adding an anticoagulant is erythrocyte sedimentation rate (ESR).
- The condition called when there are too few RBCs in the body is anemia.
Other
- The normal lifespan of a platelet is approximately 10 days.
- Granulocytes (neutrophils, eosinophils, and basophils) are a type of WBC.
- Lymphocytes and monocytes are also types of WBCs.
