TASK #1TASK #1
OBSERVING RED BLOOD CELLS, WHITE OBSERVING RED BLOOD CELLS, WHITE BLOOD CELLS AND PLATELETSBLOOD CELLS AND PLATELETS
Human Blood PartsHuman Blood Parts
Red Blood CellsRed Blood Cells (Erythrocytes = (Erythrocytes = scientific name)scientific name)–Carry oxygen (gas)Carry oxygen (gas)–Protein = Hemoglobin Protein = Hemoglobin – helps – helps
them hold on to the oxygenthem hold on to the oxygen–Most numerous Most numerous in a blood smearin a blood smear
Red Blood CellsRed Blood Cells
1.1. Draw one or two RBC’s Draw one or two RBC’s on your chart on page 2 on your chart on page 2 where it says drawings where it says drawings and labelsand labels
2.2. LabelLabel • Cell membraneCell membrane• CytoplasmCytoplasm
3.3. Number of cells in field Number of cells in field (count) = 100(count) = 100
Cell membrane
Cytoplasm
Human Blood PartsHuman Blood Parts
White Blood CellsWhite Blood Cells (Leukocytes = scientific name)(Leukocytes = scientific name)– Function in the immune systemFunction in the immune system– Much larger than RBC’sMuch larger than RBC’s– Least NumerousLeast Numerous– Surround and engulf bacteria = Surround and engulf bacteria = phagocytosisphagocytosis– Since they help fight infections a high number Since they help fight infections a high number
of them may indicate that you are sick and/or of them may indicate that you are sick and/or have a disease!have a disease!
White Blood CellsWhite Blood Cells
This is it!!
Cell membrane
Cytoplasm
Nuclear material
1.1. Draw one or two Draw one or two WBC’s on your WBC’s on your chart on page 2 chart on page 2 where it says where it says drawings and labelsdrawings and labels
2.2. LabelLabel::• Cell membraneCell membrane• CytoplasmCytoplasm• NucleusNucleus
• Number of cells in Number of cells in field (count) = 15field (count) = 15
Human Blood PartsHuman Blood PartsPlateletsPlatelets (Thrombocyte = (Thrombocyte = scientific name)scientific name)–Function in clottingFunction in clotting–““Dot-like” fragments scattered Dot-like” fragments scattered
throughout smearthroughout smear–Cell fragments, not cells!Cell fragments, not cells!–Next most numerousNext most numerous
PlateletsPlatelets
1.1. Draw some platelets on Draw some platelets on your chart on page 2 your chart on page 2 where it says drawings where it says drawings and labels.and labels.1.1. You DO NOT have to You DO NOT have to
label anything for these.label anything for these.
2.2. They are the little purple They are the little purple dots!!!dots!!!
3.3. ““t” stands for thrombocytet” stands for thrombocyte
2.2. Number of cells in field Number of cells in field (count) = 50(count) = 50
