6000- 8000 / mm3 of blood

26
Q

What are the five types of WBC

A

monocyte
lymphocyte
neutrophil
basophils
eosinophils

27
Q

Name of the two phagocytic WBC

A

monocyte
neutrophil

28
Q

The most abundant and active wbc

A

neutrophil

29
Q

Second most abundant WBC, which has round nucleus

A

lymphocyte

30
Q

The largest wbc which has kidney shaped nucleus

A

monocyte

31
Q

Which WBC is least in number

A

basophils

32
Q

Which WBC acts similar to mast cell

A

basophils

33
Q

Which WBC plays role during allergic reactions and infections

A

eosinophils

34
Q

What is the role of platelets

A

Blood clotting

35
Q

ABO system of blood group is on the basis ——— on RBC

A

antigen

36
Q

Blood group A has which antigen and which antibodies

A

antigen - A
antibody - B

37
Q

Blood group B has which antigen and which antibodies

A

antigen - B
antibody - A

38
Q

Blood group AB has which antigen and which antibodies

A

antigen - AB
antibody - nil

39
Q

Blood group O has which antigen and which antibodies

A

antigen - nil
antibody - AB

40
Q

Which blood group is called universal recipient?

A

blood group AB

41
Q

Which blood group is called universal donor?

A

blood group O

42
Q

A RH group of blood group is present

A

Plasma membrane of rbc

43
Q

What is the role of rh factor during blood transfusion?

A

If the donor is rh +ve and the recipient is RH -ve,
Then the formation of memory cells take place. So there is no major ill effect. But if large amount of formation of antibody takes place then clotting can happen

44
Q

What happens when of the donor is RH +ve and the recipient is RH -ve , and a large amount of RH antibodies is found

A

clotting

45
Q

Role of rh factor during 1st pregnancy

A

If the father is RH +ve and the mother is RH -ve the foetus will be RH +ve,

Normal development of the baby
No mixing of The blood of the mother or the baby due to placenta as a barrier
Little mixing of blood during delivery occurs due to which memory cells of rh antibodies is formed in the mother

46
Q

Role of rh factor during 2st pregnancy

A

During the first pregnancy, when the rh antibodies were formed they cross the placenta and destroyed the rbc with the baby

Which is called erythroblastosis foetalis

HDN { haemolytic disease} - may occur in the baby , Which can cause jaundice anaemia and death may occur.

47
Q

what is erythroblastosis foetalis

A
48
Q

HDN { haemolytic disease}

A

due to erythroblastosis foetalis
- may occur in the baby , Which can cause jaundice anaemia and death may occur.

49
Q

How to prevent HDN

A

Anti Rh antibody is injected to the mother immediately after the first pregnancy so that no formation of memory cell takes place. So that’s why no synthesis of rh antibody and the mother.

50
Q

Which enzyme activates prothrombin to thrombin?

A

Thrombokinase enzyme

51
Q

Which enzyme activates fibrinogen to fibrin

A

Thrombin enzyme

52
Q

Blood passes twice through heart to complete one circulation in

A

Crocodiles birds and mammals

53
Q

The human heart is present in which cavity

A

Pedicardial cavity

54
Q

The heart is made up of which four chambers

A

Left and right atria
Left and right ventricles

55
Q

Deoxygenated blood from the body parts comes through the vena cava into the

A

right atrium.

55
Q

The receiving chambers of the heart is called

A

atria or auricals

56
Q

Which Ion plays an important role in clotting?

A

calcium
