Morphological Features of RBCs Functions of the RBCs Hematological Indices Learning Objectives
Slide 3-

RBC are also known as erythrocytes or red blood corpuscles as it contains haemoglobin which turns red on binding with oxygen. It also carries carbon dioxide away from tissues to lungs. It contains certain antigens on its surface membrane that determine blood groups and makes basis of whole blood transfusion physiology. Red Blood Cells
Slide 4-

Clinical Application : Since RBC uses glucose constantly from plasma, whenever blood glucose level is to be tested, the sample is taken in the fluoride vial Red Blood Cells
Slide 5-

Red Blood Cells- Morphology-Size RBCs are anucleated discs RBC count : 4-6 million/mm3, Life span - 120 days. Central pallor is seen due to presence of less haemoglobin molecule in the centre. Size – Diameter: 7-7.8 µm, Thickness at the periphery-2.2 µm and Centre - 1 µm
Slide 6-

Shape - Normal biconcave disc Biconcave shape has many advantages: 1. Flexibility RBCs 2. Greater surface area/volume ratio Red Blood Cells- Shape
Slide 7-

RBCs Count-4-6 million/mm 3 Hb content-14-16 gm/dl O2 carrying Capacity of blood-1 gm Hb binds to 1.34 ml of O2 PCV=45±2 ml/100 ml of blood Red Blood Cells- Normal values
Slide 8-

Hematological Indices Red blood cell indices are blood tests that provide information about the average volume or size (MCV) and hemoglobin content (MCH, MCHC) of red blood cell.
Slide 9-

Mean corpuscular volume (MCV) is the average volume of a single rbc. We need values of: ▪ RBC count ▪ PCV = PCV X 10 µ³ RBCs = 80-100 µ³ Mean Corpuscular Volume (MCV)
Slide 10-

Mean Corpuscular Hemoglobin (MCH) Mean corpuscular hemoglobin (MCH) is the average amount of hemoglobin of a single rbc. We need values of: ▪ RBC count ▪ Hb = Hb X 10 pg RBCs = 27-32 pg
Slide 11-

Mean Corpuscular Hemoglobin Conc. (MCHC) Mean corpuscular hemoglobin Concentration (MCHC) is the average concentration of hemoglobin per unit volume of red blood cells. We need values of: ▪ PCV ▪ Hb = Hb X 100 g PCV 32-36 %
Slide 12-

What is normal RBC Count- a. 4000-6000/mm3 b. 4lac-6 lac/mm3 c. 4 million to 6 million/mm3 d. 4 billion to 6 billion/mm3 What is the life span of RBCs- a. 1 month b. 2 months c. 3 months d. 4 months What is the term used to describe a cell of normal color? A.-Normochromic B. Hypochromic C. Polychromic D Euchromic Self Asessment
