1

Thickening of walls or arteries, loss of elasticity

arteriosclerosis

2

Progressive disease characterised by formation of lesions in the walls of medium and large arteries called atherosclerotic plaque

atherosclerosis

3

Accumulation of atherosclerotic plaques in coronary arteries; reduced blood flow to myocardium

Coronary artery disease

4

Which organs can be affected by hypertension if don't treat it?

heart
kidney
blood vessels
brain

5

Which drugs can treat hypertension ?

diuretics
vasodialtors
ace inhibitors (block AngII formation = vasoconstrictor)
beta blockers (beta adrenergic receptor blocker)

6

What is a chest discomfort caused by atherosclerosis called?

angina

7

What makes work of heart easier?

Nitroglycerin
Calcium channel blockers
Aspirin
Surgery

8

Blood =

55% plasma
45% cells

9

Plasma proteins

albumins
globulins
fibrinogen
transferrin

10

Liver disease is associated with

edema

11

Cells of the blood

- platelets
- red blood cells
- white blood cells

12

White blood cells include

Neutrophils
Lymphocytes
Monocytes
Eosinophils
Basophils

13

In red blood cells, structures -> provide :
biconcave disks ->
spectrin ->
hemoglobin ->

biconcave disks -> flexibility
spectrin -> elasticity

14

hemoglobin is made up of

4 globine -> 4 heme groups -> 4 irons

15

What gives the red colour to hemoglobin?

Heme/iron

16

Differentiation of RBCs begins with

PROERYTHROCYTES

17

Differentiation of RBCS

hemocytoblasts
proerythrocytes
basophilic erythrocytes
polychromatic erythrocytes
reticulocytes

18

Which differentiated RBC produce haemoglobin ?

polychromatic erythroblasts

19

Reduction in platelets causes

thrombocytopenia
-> risk for haemorrhage

20

Reduction in WBCs causes

Leukopenia
-> risk of infections

21

Reduction in RBCs causes

aplastic anemia

22

Where are RBCs produced

bone marrow

23

What is erythopoiesis

is when the kidneys release erythropoietin due to low oxygen amounts -> accelerates production of RBCs

24

What is the hemoglobin made of?

- amino acids
- iron
- bilirubin

25

PCV

Packed Cell Volume = %RBC

26

An increase in PCV results in

polycythemia

27

A decrease in PCV results in

anemia

28

Which WBCs are capable of diapedesis

neutrophils
basophils

29

Which WBCs are protective against infections cause by parasitic worms and allergic reactions

Eosinophils
-> release IgE

30

Which WBCs have an important role in immunity

Lymphocytes
