Study Notes
Blood is a type of C.T content is 55% Plasma And 45% Cells Cell:1-RBCs 2- RBCs 3-platelets and Stained with leishman stain Shape:round and non nucleated Biconcave shape from side view Darkperiphery and pale center acidophilic the have Rouleaux Formation
Function of Red Blood Cells
- Deliver oxygen from lungs to body's tissues and organs
- Carry carbon dioxide from tissues and organs back to lungs for exhalation
Structure of Red Blood Cells
- Flexible, disk-shaped cells with no nucleus or mitochondria
- Contain membrane protein spectrin, which gives them unique shape and allows change of shape to fit through narrow blood vessels
- Contain protein hemoglobin, which binds to oxygen and gives blood its red color
Production of Red Blood Cells
- Produced in bone marrow through erythropoiesis
- Regulated by hormone erythropoietin (EPO) produced by kidneys
- EPO stimulates production of RBCs in response to low oxygen levels in body
Lifespan of Red Blood Cells
- Average lifespan of RBC is approximately 120 days
- Removed from circulation by spleen and destroyed at end of lifespan
- Components of RBCs recycled, and iron reused to produce new RBCs
