Question 1

Match these blood disorders labelled a. through h. with their characteristics. (Options may be used more than once or not at all.)
-associated with malaria

Accepted Answer

Haemolytic anaemia is associated with malaria because it is caused by the destruction of red blood cells by the malaria parasite.

Question 2

Match these blood disorders labelled a. through h. with their characteristics. (Options may be used more than once or not at all.)
-associated with acute loss of blood

Accepted Answer

Haemorrhagic anaemia is characterized by acute loss of blood.

Answer: B
 Pernicious anaemia is an autoimmune disorder that affects the production of red blood cells.

Answer: C
 Haemolytic anaemia occurs when red blood cells are destroyed faster than they can be produced.

Answer: H
 Sickle cell anaemia is caused by a genetic mutation that affects the shape and function of red blood cells.

Note: The remaining options are not associated with acute loss of blood. Aplastic anaemia is a disorder where the bone marrow does not produce enough blood cells. Polycythaemia is a condition characterized by an excess of red blood cells. Leukaemia is a cancer of the blood cells. Neutrophilia is an increase in the number of white blood cells called neutrophils.

Question 3

Match these blood disorders labelled a. through h. with their characteristics. (Options may be used more than once or not at all.)
-lack of intrinsic factor

Accepted Answer

Pernicious anaemia is caused by a lack of intrinsic factor, which is necessary for the absorption of vitamin B12.

Answer: H
 Sickle cell anaemia is a genetic disorder in which the red blood cells are sickle-shaped, leading to decreased oxygen carrying capacity.

Answer: A
 Aplastic anaemia is a rare disorder in which the bone marrow fails to produce enough blood cells.

Answer: C
 Haemolytic anaemia is caused by the destruction of red blood cells.

Answer: F
 Leukaemia is a cancer of the blood-forming tissues, including the bone marrow and lymphatic system.

Answer: E
 Polycythaemia is a disorder in which there are too many red blood cells in the circulation.

Answer: G
 Neutrophilia is an increase in the number of neutrophils, a type of white blood cell.

Answer: D
 Haemorrhagic anaemia is caused by excessive bleeding, such as in cases of trauma or surgery.

Question 4

Match these blood disorders labelled a. through h. with their characteristics. (Options may be used more than once or not at all.)
-uncontrolled production of white blood cells

Accepted Answer

Leukaemia is characterized by the uncontrolled production of white blood cells, which is a hallmark feature of this type of cancer affecting the blood and bone marrow.

Question 5

Match the leukocytes, labelled a. through e., with their correct characteristic. (Options may be used more than once or not at all.)
-produce antibodies

Accepted Answer

Lymphocytes are responsible for producing antibodies.

Question 6

Match these blood disorders labelled a. through h. with their characteristics. (Options may be used more than once or not at all.)
-associated with prolonged exposure to low oxygen, such as at high altitude or with chronic lung disease

Accepted Answer

Polycythemia is the condition that is associated with prolonged exposure to low oxygen environments, such as high altitudes or chronic lung diseases. This is because the body compensates for low oxygen levels by producing more red blood cells to increase the oxygen-carrying capacity of the blood.

Question 7

Match these blood disorders labelled a. through h. with their characteristics. (Options may be used more than once or not at all.)
-caused by a mutated haemoglobin

Accepted Answer

Sickle cell anemia is caused by a mutation in the hemoglobin gene, leading to the production of abnormal hemoglobin known as hemoglobin S. This causes red blood cells to assume a sickle shape, which can lead to various complications.

Question 8

What are the different kinds of white blood cells, and how are they produced

Accepted Answer

The answer of What are the different kinds of white...

Question 9

Match these blood disorders labelled a. through h. with their characteristics. (Options may be used more than once or not at all.)
-lack of red blood cell production due to poisoning of the bone marrow

Accepted Answer

Aplastic anemia is characterized by the failure of the bone marrow to produce red blood cells, often due to its poisoning or damage.

Question 10

Match these blood disorders labelled a. through h. with their characteristics. (Options may be used more than once or not at all.)
-premature rupture of erythrocytes

Accepted Answer

Haemolytic anaemia is the premature rupture of erythrocytes.

Question 11

Accepted Answer

The answer of What factors influence the rate of erythrocyte...

Question 12

Match the leukocytes, labelled a. through e., with their correct characteristic. (Options may be used more than once or not at all.)
-the most abundant type of granulocyte

Accepted Answer

Neutrophils are the most abundant type of granulocyte.

Answer: B
 Eosinophils are not the most abundant type of granulocyte.

Answer: C
 Basophils are not the most abundant type of granulocyte.

Answer: D
 Monocytes are not granulocytes.

Answer: E
 Lymphocytes are not granulocytes.

Question 13

Match the leukocytes, labelled a. through e., with their correct characteristic. (Options may be used more than once or not at all.)
-destroy parasitic worms

Accepted Answer

Eosinophils are known to destroy parasitic worms through a process called degranulation, where they release enzymes and other substances that cause damage to parasites. None of the other leukocytes listed have a specific role in fighting parasitic infections.

Question 14

Match these blood disorders labelled a. through h. with their characteristics. (Options may be used more than once or not at all.)
-vitamin B₁₂ is not absorbed

Accepted Answer

Pernicious anaemia is caused by the inability to absorb vitamin B₁₂.

Answer: H 
 Sickle cell anaemia is a genetic disorder that results in abnormal haemoglobin, leading to misshapen red blood cells that can cause blockages in blood vessels.

Answer: C 
 Haemolytic anaemia occurs when red blood cells are destroyed faster than they can be produced.

Answer: D 
 Haemorrhagic anaemia is caused by a loss of blood usually as a result of injury or bleeding disorders.

Note: The remaining options (A, E, F, G) were not used as they do not match any of the listed characteristics.

Question 15

Match these blood disorders labelled a. through h. with their characteristics. (Options may be used more than once or not at all.)

Question 17

Match these blood disorders labelled a. through h. with their characteristics. (Options may be used more than once or not at all.)
-frequently associated with bacterial infections

Accepted Answer

Neutrophilia is often associated with bacterial infections as it involves an increase in neutrophils, which are a type of white blood cell that responds to bacterial infections.

Question 18

Match the leukocytes, labelled a. through e., with their correct characteristic. (Options may be used more than once or not at all.)
-the first phagocytes to arrive at site of bacterial invasion

Accepted Answer

Neutrophils are the first responders to bacterial invasion and are highly phagocytic, meaning they can engulf and digest invading bacteria. Eosinophils, basophils, and monocytes are also leukocytes, but they are not typically the first to arrive at the site of bacterial invasion. Lymphocytes play a crucial role in the immune response by producing antibodies, but they are not phagocytic.
