Antibodies will destroy invading cells by causing them to either stick together or burst, making it easier for the .......... to clear them up.

1. erythrocytes
2. lymphocytes
3. phagocytes
4. platelets

Fill in the gap:
Platelets near the wound cause the blood to produce thread-like proteins called ...... .

1. fibrous
2. fibrin
3. fibrinogen
4. mesh

Fill in the gap:

that may have entered the body through the cut.

1. foreigners

For blood groups A, B, AB and 0 one can see both factors (antigens A and B) and antibodies (anti-A and anti-B). Which of those blood factors and antibodies are present in the blood of a person with blood group 0?

1. no factors, no antibodies
2. no factors, anti-A and anti-B
3. antigens A and B, no antibodies
4. antigens A and B, anti-A and anti-B

Van Willebrand disease is a hereditary clotting disorder. Patients with a severe disorder can be treated by administering a specific medicine. Because this medicine is made from blood plasma of healthy donors, it contains small quantities of anti-A and of anti-B. Administering large quantities of this medicine can cause red blood cells of particular blood groups to start clumping together. Patients with one particular blood group can be treated without any risks. What blood group can this be?

1. Blood group A
2. Blood group B
3. Blood group AB
4. Blood group 0

Emma and Brad are travelling in Uganda. Unfortunately, they were involved in a car accident and Emma was severely injured. Emma's blood group is B. The village hospital does not have any blood of group B available. Brad had blood group A and he offers to donate his blood. The doctor says that he is not a suitable donor. Why? Emma's blood contains .....

1. antigen A
2. antigen B
3. anti-A
4. anti-B

Substances that may be present in the tissue fluid include carbon dioxide, glucose and oxygen. Which of these substances are transported to the cells by the tissue fluid?

2. Only glucose and oxygen
3. Only carbon dioxide and oxygen
4. Glucose, carbon dioxide and oxygemn

The figure at the right is a schematic drawing of a number of
blood vessels: a vein, capillaries, a lymph vessel and an artery.

vessel correctly?

1. arrow 1
2. arrow 2
3. arrow 3
4. arrow 4

The figure at the right is a schematic drawing of a number of
blood vessels: a vein, capillaries, a lymph vessel and an artery.
Could there be white blood cells at position P in the drawing?
And could there be oxygen at position P?

1. Neither white blood cells nor oxygen
2. Only white blood cells
3. Only oxygen
4. Both white blood cells and oxygen

In a test tube, which is heavier: the layer of white blood cells of the layer of red platelets? Give a reason for your answer.

John suffers anaemia: a condition which causes him to get tired and weak very quickly. Sometimes he looks very pale and now and then he gets short of breath. His doctor did a blood test. He told him that his blood cannot transport oxygen as well as it should. He has a 'low blood cell count'.

- what substance in your red blood cell is responsible for binding and transporting oxygen in blood cells?
- why does anaemia cause people to get tired and weak?
