Q

Main functions of blood

A

1) transportation - nutrients/waste/hormones/antibodies
2) regulation - temp, pH, chemicals of ECF
3) protection - clotting, white blood cells

Q

What is another name for red blood cells?

A

Erythrocytes

17
Q

What is another name for white blood cells?

A

Leukocytes

18
Q

What is another name for platelets?

A

Thrombocytes

19
Q

What is the key function of red blood cells?

A

To carry oxygen

20
Q

What is the key function of red blood cells?

A

To carry oxygen

21
Q

What is the shape of a red blood cell?

A

Biconcave disc shape

22
Q

Which type of blood cells has no nucleus?

A

Red blood cell

23
Q

When oxygen pressure is high, what does Hb do?

A

Takes up oxygen (eg. The lung)

24
Q

Where oxygen pressure is low, what does Hb do?

A

Hb gives up oxygen (eg. In respiring tissue)

25
Q

At what pH does haemoglobin dissociate at?

A

pH 7.4

26
Q

What is Bohr Shift

A

Changes in the oxygen dissociation curve as a result of carbon dioxide levels

(EG. When the partial pressure of carbon dioxide in the blood is high, Hbs affinity for oxygen is reduced)

27
Q

Types of White Blood Cells?

A
  • Basophil
  • neutrophil
  • monocyte
  • Lymphocyte
  • Eosinophil
28
Q

What type of WBC releases histamines?

A

Eosinophils

29
Q

What type of WBC mediates immune responses?

A

Lymphocytes

(Lymphocytes make antibodies in response to infection/vaccine)

30
Q

If a person has Type B blood, what antibodies do they have

A

Anti-A

31
Q

If a person has type AB what antigens and anti-bodies do they have?

A

Both A and B Antigens
Neither antibodies

32
Q

If a person has Type O blood what antigens/antibodies do they have

A

Neither A/B antigen
Both A/B antibodies

33
Q

What blood type is a universal recipient?

A

Type AB

34
Q

What blood type is a universal Donor

A

Type O

35
Q

What is the main function of platelets?

A

To help stop blood loss from damaged blood vessels

36
Q

What is Haemostasis?

A

Body’s normal response for the prevention/stopping of bleeding

37
Q

What are the PHASES of HAEMOSTASIS

A

1) vasoconstriction - reduces blood loss for several minutes
2) platelets plug formation
3) Blood clotting - production of thrombin

38
Q

What is the function of the spleen

A

Filters blood
Stores RBC/WBC/Platelets
