Q

Blood - Physical Characteristics:

A

• Sticky, opaque fluid with a metallic taste
• Color varies from scarlet to dark red.
• Blood is denser than water and about five times more viscous, largely because of the formed elements.
• Slightly alkaline (pH – 7.35-7.45)

25
A microliter of blood contains 5 million of red blood cells.
Red Blood Cells (Erythrocytes)
26
Function: Transports oxygen and carbon dioxide
Red Blood Cells (Erythrocytes)
27
Red Blood Cells (Erythrocytes)
a. Hemoglobin consists of globin (two alpha and two beta polypeptide chains) and four heme groups. b. Iron-containing heme pigment.
28
Spherical cells with a nucleus
White Blood Cells (Leukocytes)
29
A microliter of blood contains 5000-10,000 white blood cells.
White Blood Cells (Leukocytes)
30
Body’s defense against pathogens
White Blood Cells (Leukocytes)
31
Five types of White Blood Cells (Leukocytes):
• Neutrophil • Basophil • Eosinophil • Lymphocyte
32
Minute fragments of cells, each consisting of small amount of cytoplasm surrounded by cell membrane.
Platelets (Thrombocytes)
33
A microliter of blood contains
150,000- 400,000 platelets.
34
A microliter of blood contains 150,000- 400,000 platelets.
Platelets (Thrombocytes)
35
Function: Preventing Blood loss
Platelets (Thrombocytes)
36
A laboratory examination of blood yields information that can be used to evaluate a person’s health. This involves CBC, Differential white blood cell count, platelet count, prothrombin time, etc.
Diagnostic Blood tests
37
Analysis of blood that provides much useful information
Complete Blood Count (CBC)
38
Blood test (Red Blood Count)
Normal Values: Male: 4.6-6.2 million per microliter of blood Female: 4.2-5.4 million per microliter of blood
39
Blood test (Hemoglobin Measurement)
Normal Values: Male: 14-18 grams per 100mL of blood Female: 12-16 grams per 100mL of blood
40
Blood test (Hematocrit Measurement)
Normal Values: Male: 40-52% of the blood Female: 38-48% of the blood Male: 40-52% of the blood Female: 38-48% of the blood
41
Blood test (White Blood Count)
5000-9000 per microliter of Blood
42
Determines the percentage of each of the five kinds of white blood cells.
Differential White Blood Cell
43
Differential White Blood Cell normally, each kind account for:
• 60-70% - neutrophils • 20-25%. – lymphocytes • 3-8% - monocytes • 2-4% - eosinophils • 0.5-1% - basophils of the entire white blood cell
44
The blood’s ability to clot can be assess through platelet counts and prothrombin time measurement.
Clotting
45
The blood’s ability to clot can be assess through:
Platelet count and Prothrombin Time measurement
46
Normal value: 150, 000 – 400, 000 platelets per microliter of blood.
Platelet Count
47
Platelet Count
48
Normal value: 150, 000 – 400, 000 platelets per microliter of blood.
Platelet Count
49
calculates how long it takes for the blood to start clotting. Normally – 9-12 seconds.
Prothrombin Time Measurement
50
The composition of materials dissolved or suspended in the plasma can be used to assess the functioning of many of the body’s systems
Blood chemistry
51
Glucose, electrolytes, sodium, potassium, chlorides, lipid, etc.
Blood chemistry
52
Process of blood loss prevention
Hemostatis
53
It involves many clotting factors normally present in plasma as well as several substances that are released by platelets and injured tissue cells.
Hemostatis
54
smooth muscle contracts causing vasoconstriction
Vascular Spasm
55
injury lining of vessel exposes to collagen fibers. Platelets also adhere and release chemicals that cause formation of a plug.
Platelet plug formation
56
fibrin forms a mesh that traps RBC and platelets forming a clot.
Coagulation
57
transfer of blood or blood components from one individual to another
Transfusion
58
introduction of a fluid other than blood, such as saline or glucose solution, into the blood.
Infusion
59
protein that a surface of each red blood cell carries.
Antigen
60
the blood plasma carries antibodies against the antigens of the other blood types.
Antibodies
61
clumping or rupture of blood cells and clotting within blood vessels.
Transfusion reaction
62
Caused by interactions by antigens and antibodies that can result into:
• Agglutination – clumping of blood cells • Hemolysis – rupture of the blood cells
63
System used to categorize human blood.
ABO Blood Group
64
the person who gives blood
Donor
65
the person who receives blood
Recipient
66
Responsible for hemolytic disease of the newborn, which can occur when the fetus is Rh-positive and the mother is Rh-negative
Rh blood group
67
Rh-positive blood has
Rh antigen
68
Rh-negative blood
does not (lacks specific antigen)
