25
Hb+CO2
only 20% of all CO2 is carried on hemoglobin
26
Hb+CO
carbon monoxide
27
anemia
decreased amount of hemoglobin
28
erythropoiesis
erythrocyte production
29
regulation of erythropeisis
EPO increase rbc count by stimulation hemopoiesis
30
EPO
erythropoietin
31
EPO cycle
decrease o2 detected in kidneys, EPO release, increase rbc production in marrow which increase o2 carrying capacity, signals kidney to decrease EPO
32
functions of blood
transport maintenance protection
33
what does blood transport
gases, nutrients, waste molecules, processed molecules | regulatory molecules
34
maintenance of
circulatory fluid volume pH body temperature
35
components of blood
plasma | formed elements
36
how much is plasma in the blood
>90% H2O
37

intracellular interstitial space plasma
38

albumin globulins fibrinogen
39

bone marrow | lymphoid tissue
46

biconcave disk with no nucleus
53

heme pigment with Fe + globulin protein
54
oxyhemoglobin
Hb+O2 | bright red blood color
55
deoxyhemoglobin
hb - O2 | darker blood
56
Hb+CO2
only 20% of all CO2 is carried on hemoglobin
57
Hb+CO
carbon monoxide
58
anemia
decreased amount of hemoglobin
59
erythropoiesis
erythrocyte production
60
regulation of erythropeisis
EPO increase rbc count by stimulation hemopoiesis
61
EPO
erythropoietin
62
EPO cycle
decrease o2 detected in kidneys, EPO release, increase rbc production in marrow which increase o2 carrying capacity, signals kidney to decrease EPO
63
the recycling of RBCs
``` macrophages use lysozymes on hb globin broken into amino acids Fe++ transported by transferrin non-iron remainder of heme converted to bilirubin removed in urine and feces ```
64
life span of rbc
90-120 days
65
function of bilirubin
darkens stool | gives urine color
66
jaundice
yellowed appearance to skin and sclera
67
causes of jaundice
liver is not processing free bilirubin from blood | sudden hemolysis of rbcs can overload the removal system with bilirubin
68
hemorrhagic anemia
result from blood loss either from trauma or medical conditions
69
hemolytic anermia
rupture prematurely. hemoglobin abnormalities, mismatched transfuion or infections
70
aplastic anemia
destruction or inhibition of red marrow by drugs or chemicals
