1

What are the four Humors?

Blood
Phlegm
Yellow bile
Black bile

2

What is the role of platelets?

Looks for small breaks in blood vessels and acts a primary plug, surface for clotting factors to make clot, repair breaks

3

What is Haematology?

The study and treatment of blood

4

What can Haemopoiesis cells do?

develop into different cell types, stimulate stem cells with different growth factors to achieve different cell types, greatest ability of self renewal, mobilise into peripheral blood, undergo apoptosis, collect from bone

5

What do red blood cells do?

Deliver oxygen

6

Why are red blood cells that shape?

Biconcave shape and lipid bilayer so flexible and no nucleus or organelles to maximise space to carry Oxygen and carbon dioxide

7

What are the 5 white cells?

Neutrophils
Eosinophils
Basophils
Lymphocytes
Monocytes (macrophages)

8

Which 4 cells are the first line killers of the innate immune system?

Neutrophils, Eosinophils, Basophils and monocytes

9

What do the first line killers do?

Smell organisms chemotaxis and engulfs and kills them using deadly contents of their granules

10

What do macrophages also do other than kill cells?

present antigen to lymphocytes

11

What are the two types of lymphocytes?

B cells and T cells

12

What do B cells do?

Produce antibodies

13

What do T cells do?

Recognise foreign proteins and activate other cells, directly kill and inhibit immune response

14

What do Natural Killer cells do?

Stimulate sick cells to self destruct (apoptosis)

15

What do arteriole clots predominantly include?

Platelets

16

What do venous clots predominantly include?

Red blood cells and fibrin

17

What is used in Blood transfusions?

Red blood cells, plasma and platelets

18

What else other than blood can be transfused?

Stem cells

19

What may a high blood count show?

Polycythemia, leukemia, thrombocythemia

20

What may a low blood count show?

Anaemia, Leucopenia, Thrombocytopenia

21

What do abnormal full blood count results usually show?

Mostly reactive to other conditions or treatments of these conditions not bone marrow dysfunction

22

What are the primary haematological disorders?

Haematological malignancies e.g. Leukaemia, primary haemostatic failure disorders (clotting/bleeding) and red cell disorders

23

What is cellular logistics?

Understanding at the genetic an protein level
