Andrey Zvonkov is an anesthesiologist-resuscitator and emergency physician with many years of experience, the author of the bestseller “While the ambulance is driving.” For more than 15 years he managed the blood transfusion service in a private clinic, and this experience helped him write the book that you opened. Why are blood clots dangerous? What are sclerosis and anemia? Why does a person lose consciousness when wounded? What causes the feeling of shortness of breath after exercise? Why is blood liquid? Is cholesterol really bad? Why don’t transfusiologists like doing extra blood transfusions? Can healthy cells harm the body? What is iron deficiency? How are blood and lymph connected? Dr. Zvonkov uses simple examples to show how blood cells are structured, what types they are and what they are responsible for. You will learn how immunity works, what substances the blood carries and why our body needs them. The book covers a variety of blood topics, from red blood cell function and blood sugar levels to autoimmune diseases and anemia.
