25
hemoglobin is broken down into how many globin and heme.
4. Globin chain 4 heme group
26
• red blood cells contain the?
Protein hemoglobin
27
General function of RBC
• is to transport oxygen or pick up oxygen from the lungs to be distributed to the various tissues of the body. In exchange, it transports carbon dioxide that was used by your tissues to the lungs.
28
is the actual red pigmented molecule.
Heme
29
 each contains or each heme group contains how many iron atom which can bind to an oxygen molecule.
1 iron atom
30
How many heme group in 1 RBC
4 heme group
31
How many oxygen molecule can hemoglobin carry?
4
32
If it is bound to oxygen, it has a what color?
Bright red
33
If not bound to any oxygen, what’s the color?
Darker red
34
The production of your RBCs is stimulated by
Low blood oxygen levels
35
• is stimulated by low blood oxygen, levels. This will release what hormone?
Erythropoietin
36
Releasing erythropoietin in where?
Kidneys
37
What happens when the RBCs have become old or has reached its lifespan or is abnormal or damaged?
• it will go to the spleen and in the spleen, it is degraded through the process of phagocytosis by the macrophages.
38
What happens to the globin in spleen?
it is degraded or broken down into its simplest form which is the amino acid. So this amino acid is being reused by the body.
39
What happens to heme
Heme is converted into bilirubin which is a yellow pigment.
40
• is essential in breaking down or emulsifying fat from the food that we eat.
Bile
41
the brownish or yellowish pigment of your stool.
Stercobilin
42
the yellow pigment that is found in your urine.
Urobilin
43
what happens to hemoglobin When the RBCs are broken down?
• the hemoglobin is also broken down. The globin part of the hemoglobin is protein, so therefore, it is broken down into its simplest form, which is amino acids. And then this amino acid is being recycled or reutilized by the body.
44
• these are spherical shaped cells larger than RBCs.
WBCs
45
Are WBC nucleated or annucleated
Nucleated
46
• the movement of the WBCs is called
Amoeboid
47
• Still under deformed elements, these are fragments of cells as they are derived from megakaryocytes. So, please remember that they are just fragments of cells
Platelets
48
Platelets are nucleate or annucleate?
Annucleate
49
Major function of platelets
Hemostasis
50
• is the process to prevent and stop bleeding. So these are the mechanisms of the body that would stop the bleeding.
Hemostasis
51
Stasis means? Hemo means?
Stop Blood
52
the 3 processes involved in hemostasis are the following.
1. Vascular spasm 2. Platelete plug formation 3. Blood clotting itself
53
• So the goal of the vascular spasm
Contract or constrict
54
This will release ______ in the kidneys to stimulate the bone marrows to produce red blood cells.
Erythropoietin
55
• the movement of the WBCs is called ?
Ameboid movement
56
It is to protect the body against pathogen and remove dead cells and debris from the tissues by phagocytosis.
WBCS
57
Both of these will induce vasospasm. Or vascular spasm.
Thromboxane from platelet Endothelin from endothelial cells
58
• is the accumulation of platelets that can seal up a small break in the blood vessel.
Platelet plug
59
endothelial cells will also release this very important factor,
Von willebrand factor
60
endothelial cells will also release this very important factor,
Von willebrand factor
61
importance of your von Willebrand factor. So, with the collagen exposed, plus the presence of your von Willebrand factor, your platelets will be able to adhere. This is the process called
Platelet adhesion
62
they form a bridge between the exposed collagen and the platelets.
Von willebrand factor
63
they form a bridge between the exposed collagen and the platelets.
Von willebrand factor
64
The platelets on that site will release chemicals such as your
ADP THROMBOXANE
65
Once there's already receptors for fibrinogen on the platelets, the platelets will bind to fibrinogen. This is the process
Platelet aggregation
66
Stages of blood clotting
Activation of blood clotting factor Conversion of prothrombin to thrombin Conversion of fibrinogen to fibrin
67
Stages of blood clotting
Activation of blood clotting factor Conversion of prothrombin to thrombin Conversion of fibrinogen to fibrin
68
• Prothrombin(inactive) converts to thrombin (active form) through the
Prothrombinase enzyme
69
blood clotting is the conversion of fibrinogen into fibrin through the help of your
Thrombin
70
o This is the organ that creates or synthesizes your clotting factors.
Liver
71
cutting factors require what vitamin for synthesis.
Vitamin k
72
Vitamin K can be synthesized not only taken from the food that we eat but also from the?
Bacteria
73
chemicals that are found in the blood are your?
Heparin Antithrombin
74
Anticoagulants in the blood
o antithrombin o heparin
75
Abnormal clots
Thrombus Embolus
76
o are clots that are attached at the damaged or diseased areas of the blood vessel.
Thrombus
77
o this is when the thrombus breaks loose and begins to flow through the circulation
Embolus
78
two processes to complete the process of hemostasis.
Clot retractions Fibrinolysis
79
these 2 are present, it signifies that the platelet is able to contract.
Actin and myosin filaments
80
So the main actor in the process of fibrinolysis is your
Plasminogen
81
So the main actor in the process of fibrinolysis is your
Plasminogen
82
inactive plasma protein, so it has to be converted to its active form
Plasminogen
83
This is released from the surrounding tissues, and then this can stimulate the conversion of plasminogen to plasmin
Tissue plasminogen activator TPA
84
is a medication that is actually, injected, IV, to the patients who are sus suspected with, blood clots. So they will help dissolve the clots by converting plasminogen to plasmin, and then the plasmin itself will break down the fibrin
Streptokinase
85
