Q

How are erythrocytes produced?

A
  1. When there is decrease in blood O2, kidney receptors detect this change
  2. Kidney releases ERYTHROPOIETIN
  3. It stimulates RBC/Erythrocytes production in Red B.M.
  4. There will be increase in blood O2 (many RBC=High oxygen

Q

Explain fate of old erthrocytes

A
  1. Old red blood cells are removed from blood by macrophages in spleen and liver
  2. Hemoglobin is broken down and separated into 2 (Globin & Heme)
  3. Globin= broken down into amino acids
  4. Heme= converted to bilirubin

Q

what is the process of blood typing

A
  1. add 3 drops of blood to glass slide
  2. add ANTISERA A, B, and D sequentially
  3. mix antisera properly in blood with toothpicks
  4. allow to stand for 2-3 min. and note down result

Q

Explain interpretation of CBC and blood diseases

Study These Flashcards
A

A CBC consist of
- Red blood cell count
- hemoglobin & hematocrit measurements
- white blood cell count

18
Q

What blood type: reacted to all anti drops

19
Q

What blood type: reacted to no anti

20
Q

This term refers to the inability of blood to clot properly

Study These Flashcards
A

haemophilia/hemophilia

21
Q

Platelets are produced in bone marrow and are pinched off fragments from ___

Study These Flashcards
A

megakaryocytes

22
Q

2 types of Leukocytes ____ &____

Study These Flashcards
A

granulocytes & Agranulocytes

23
Q

Define granulocytes

Study These Flashcards
A

Type of WBC that has small/specific granules

24
Q

Define agranulocytes

Study These Flashcards
A

Type of WBC that has no specific granules in their cytoplasm

25
2 examples of agranulocytes and their function? "M.L
Monocytes- produce macrophages Lymphocytes- produce antibodies
26
3 examples of granulocytes and their function? N.EO.B
Neutrophils- phagocytes Eosinophils- destroy parasites Basophils- release histamine & heparin
27
This refers to the clumping of particles/ blood cells Effect: clog blood vessels
Agglutination
28
____ is a network of threadlike protein fibers, called fibrin, that traps blood cells etc.
Clot
29
Explain the process of blood clotting
1. Prothrombinase production- a.) Inactive clotting factors with exposed connective tissue = C.F activation or b.)Thromboplastin released from injured tissue activates clotting factors -Initial activations happen until prothrombinase/prothrombin activator is formed 2. Thrombin Production- prothrombinase converts to prothrombin (inactive clotting factor) to thrombin (active) 3. Fibrin production- thrombin converts plasma protein fibrinogen to fibrin *Fibrin=clot ________________ Clotting factor activation>prothrombinase>thrombin>fibrinogen>fibrin
30
Disease in blood- septicemia is what?
blood poisoning
31
Malaria is?
caused by a protozoan introduced into blood by mosquito
32
AIDS/ acquired immunodificiency syndrome
caused by HIV
33
This is the process of removing nucleus during development
Enucleation
34
Where is erythropoietin produced?
Kidney. It's stimulates production of RBC to RBM
35
Disorder- high WBC count
Leukocytosis
36
Disorder- low WBC count
Leukopenia
37
What is the shape of hemoglobin and why?
Biconcave. So that it can fit through blood vessels
38
what is the most common WBC
neutrophil
39
Largest WBC
monocyte
40
What EBC are granulocytes and what are agranulocytes
granulocytes- neutrophil, eosinophil, basophil agranulocytes- monocyte,
