Exercise 5. Read and translate the text:

Blood

Blood is a reddish bodily fluid that is pumped by the heart through the arteries and veins. It delivers necessary substances such as nutrients and oxygen to the body cells and transports metabolic waste products away from the cells. It is composed of blood cells floating in blood plasma. The blood cells are mainly red blood cells, white blood cells and platelets. The average person has about 5 liters of blood; it makes up 7 to 8 percent of a person's body weight.

Red blood cells (RBCs), or erythrocytes, are the most numerous cells in the blood. In men, there are about 5,200,000 RBCs per cubic millimeter (microliter), and in women there are nearly 4,600,000 RBCs per cubic millimeter. The ratio of cells in normal blood is 600 RBCs for each white blood cell and 40 platelets. RBCs have no nuclei. The primary function of red blood cells is to transport oxygen from the lungs to the cells of the body. RBCs have an iron-containing protein called hemoglobin. It is hemoglobin that actually carries the oxygen and gives blood its red color. Besides carrying oxygen to the cells of the body, the RBCs help to remove carbon dioxide (CO₂) from the body.

White blood cells (WBCs), or leukocytes, are a part of the immune system and help human bodies fight infection. It is leucocytes that can be transported to an area where an infection has developed. In a normal adult body there are 4,000 to 10,000 WBCs per microliter of blood. When the number of WBCs in the human blood increases, this is a sign of an infection somewhere in the body.

Thrombocytes, also called platelets, are responsible for blood clotting (coagulation). There are approximately 150,000 to 400,000 platelets in each microliter of blood. Platelets are formed in the bone marrow. They do not have a nucleus and do not reproduce.

Plasma is a fluid that is the blood's liquid medium. It is straw-yellow in color. It is plasma that makes 55% of blood. The blood plasma volume totals of 2.7–3.0 liters (2.8–3.2 quarts) in an average human. It is essentially an aqueous solution containing 92% water, 8% blood plasma proteins, and trace amounts of other materials. Plasma circulates dissolved nutrients, such as glucose, amino acids, and fatty acids (dissolved in the blood or bound to plasma proteins), and removes waste products, such as carbon dioxide, urea, and lactic acid.

Medical terms related to blood often begin with hemo- or hemato- (also spelled haemo- and haemato-) from the Greek word “haima” for "blood".
