1
Write down what you know about the blood. Write down what you know is NOT true about the blood.
3
Blood minus its cells Composition › Water containing many dissolved substances (foods, salts, hormones) Amount of blood = 4-6 L (7%-9% of body weight) Slightly alkaline
4
Blood sample spun down using centrifuge
5
RBCs (erythrocytes) WBCs (leukocytes) Platelets (Thrombocytes) Formed in bone marrow from myeloid tissue
6
Artery showing size relation of formed elements in the blood (red blood cells, white blood cells and platelets
7
Cell maturation chart
8
Electron scanning microscope images of formed elements in blood in relation to each other
9
Red blood cells (RBCs) 4.5-5 million per mm 3 of blood Disc shaped Structure: › Without nuclei Function: › Transport oxygen and carbon dioxide
10
Image showing red blood cells in relation to other cells
11
White blood cells (WBCs) 5,000-10,000 per mm 3 of blood Structure: › Granular: neutrophils, eosinophils, basophils › Non-granular: lymphocytes and monocytes Function: › defense
12
Microscope, stained image of red blood cells and white blood cells. This is a normal blood sample.
13
This is a after colored image from an electron scanning microscope showing the white blood cell in relation to the red blood cell
14
Also called platelets 300,000 per mm 3 of blood Play an essential role in blood clotting
15
Stained, microscopic image of a blood sample showing platelets and red blood cells
16
Electron scanning microscope showing a red blood cells surrounded by platelets
17
ABO system › Type A – type A antigens in RBCs; anti-B type antibodies in blood › Type B – type B antigens in RBCs; anti-A type antibodies in blood › Type AB – type A and type B antigens in RBCs; no anti-A and no anti-B antibodies in blood › Type O – no type A and no type B antigens in RBCs; anti-A and anti-B antibodies in blood
19
Chart showing characteristics in blood, plasma and what the coordinating blood type would be
20
Chart showing the percentages of blood type availability
21
Rh-positive blood – Rh factor antigen present in RBCs Rh-negative blood – no Rh factor antigen present in RBCs; no anti-Rh antibodies present unless exposed
22
Rh factor showing blood surface antigens and antibodies
23
Myel/o – bone marrow Plasm/o – plasma Splen/o – spleen Thromb/o - clot
24
Anemia – reduction in the amount of hemaglobin in the red blood cells Embolus – blood clot or foreign material Hemophilia – inherited blood disease most commonly caused by a deficiency of coagulation factor VIII Leukemia – malignant disease characterized by excessive increase in abnormal white blood cells formed in bone marrow
25
Bone marrow aspiration – a syringe used to aspirate bone marrow from ilium Bone marrow biopsy – a needle puncture to obtain bone marrow sample Bone marrow transplant – infusion of normal bone marrow cells from a donor for patient with leukemia
26
Coagulation time – blood test to determine time it takes for blood to form a clot Complete blood count – basic blood screening Differential count – explains the number of different kinds of cells Hematocrit – blood test to measure volume and number of red blood cells
27
Hemoglobin – blood test to determine the concentration of oxygen carrying components (hemoglobin) in red blood cells Prothrombin time – used to determine certain coagulation activity defects and to monitor anticoagulation therapy
28
Hyperlipidemia – excessive amounts of fats in the blood Anticoagulant – agent that shows the clotting process Hemorrhage – rapid loss of blood
29
Disease/disorders › Hematoma › Multiple myeloma › Pancytopenia › Thrombosis › Thrombus › splenomegaly Complementary terms › Hematologist › Hematology › Hematopoiesis › Hemolysis › Hemostasis › Myelopoiesis › Plasmapherisis › Thrombolysis
