Answer 1

Contain Haemoglobin

iron rich protein that carries O2

Question 2

Answer 2

Erythropoietin is a hormone produced in the kidneys (remember the renal module) and is key for effective erythropoiesis. Normal erythropoiesis results in the production of red blood cell formation.

Question 3

Answer 3

the increased destruction red blood cells resulting in an overall reduction in red cell numbers.

Question 4

What are Leukocytes -

Answer 7

have a role in allergic and inflammatory responses

Question 8

What is Neutropenia -

Answer 8

The total number of neutrophils in the blood is low

Neutropenia is currently defined as a neutrophil count less than 2.0 x 109/L.

Question 9

What is Thrombocytopenia -

Answer 9

referred to as low levels on platelets in the blood.

Question 10

Provide a brief description of thrombocytopenia

Answer 10

A low platelet count that leads to clotting problems (haemostasis).

Question 11

Normal Haemoglobin concentration

Answer 11

(normal female range 12 - 17.5 g/dL)

Question 12

Normal WBC count

Answer 12

(normal range 4.9 - 11 x 109/L)

Question 13

Normal absolute neutrophil count

Answer 13

(normal = 2 - 7.5 x 109/L)

Question 14

Normal platelet count

Answer 14

(normal range 150 - 400 x 109/L)
