5. Translate into Russian:

1. The blood is a complex fluid in which great numbers of disc-shaped bodies known as red corpuscles float. 2. The red corpuscles have to do with the transportation of oxy­gen from the lungs throughout the body and with the re­verse process of getting back the carbon dioxide for excre­tion via the lungs. 3. There are also white corpuscles, in much lesser numbers, which function in the defence of the body against invading disease organisms. 4. All parts of the body, with the exception of the outer horn and hoof, are intersected by blood vessels or tubes in which blood flows. 5. The arterioles, of which there are millions and millions in the body, break up, in most cases, each into a bunch of tubes called capillaries. 6. The transference of materials including nutrients and oxygen from the blood to the tissues, and of carbon dioxide and other waste materials from the tissue to the blood, takes place in the regions of the capillaries which are distributed all over the body. 7. Large quantities of animal blood are usually needed for different tests. 8. Complement is a substance which is present to a great or lesser extent in the fresh blood serum of all mammals. The most satisfactory complement is derived from a guinea-pig. 9. The fluid of the blood carries nutrients and the regulatory chemicals secreted by the ductless glands of the body as well as health-preserving materials round to the various tissues of the body, and it returns waste materials to the kidneys for excretion. 10. The volume of blood cells is generally less than that of plasma.
