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.
Test your knowledge of blood cells and their functions. Identify the blood cell responsible for carrying oxygen, immune response, and blood clotting, as well as the components serving as a medium for blood cell circulation.
