Task 4. Read and translate the text:

The prefix haem- means blood The study of blood is haematology, haemophilia is a disease of the blood and a haemorrhage is a bruise. In humans, blood forms in the bone marrow by a process called haemogenesis. Blood circulates around the body through the cardiovascular system of arteries, veins and capillaries. Blood has many functions. It distributes oxygen, keeps the body warm, and removes waste. More than half of the blood in the body is a fluid called plasma – plasma is mostly water. The rest of the blood is made up of red cells which carry oxygen, white cells which protect against disease, and platelets which heal wounds. When someone loses a lot of blood they need a transfusion. There are different types of human blood and medics usually use the ABO system which puts blood into four main groups: A, B, AB, and O. The donor blood must be compatible with the blood of the recipient, because a transfusion of the wrong blood can be fatal. Medical conditions affect blood in many ways, so a blood test is a good way to get information about a patient’s state of health. The shape, size, behaviour and number of blood cells can provide information about kidney and liver function, about levels of hormone, glucose and cholesterol, and about a patient’s immune system.

Task 5. Decide whether the following statements are true (T) or false (F) according to the text.

1. Bone marrow is formed by haemogenesis.

2. Blood cells are mostly water.
