There was a bruise (肿) on the left side of his forehead and some slight bleeding from his left ear. He was taken to hospital for examination but X-rays did not reveal any other in juries.

36、Blood When you cut yourself, some very small blood vessels break, and a little b lood escapes. Soon the blood clots. It forms a thick jelly that plugs the cut. F rom such experiences we all learn that blood is red, thicker than water, sticky, and salty in taste. If a drop of blood is examined under a microscope, many round cells can be seen. These are the red cells. Seen singly, they appear faint pink or yellow ra ther than red. Only the thickness of many cells bunched together makes blood loo k red. Red cells are only one kind of solid matter that is found in blood. Some o f the solids are dissolved in the watery part. Other solids are in suspension. T hat is, they are distributed through the blood like grains of sand in a glass of water that has been stirred. In laboratories blood can be separated into two ma jor parts: a jelly like mass of cells and a thin, straw colored liquid. The liquid part of the blood is called plasma. It is thin and clear because e it is 90 percent water, but many chemicals are dissolved in it. These chemicals include those which build bones, and those which are needed by the heart and mus cles. Plasma contains salt, which is why blood tastes salty. Plasma also carries sugar and tiny drops of fat — fuels for the body’s cells. Most of the solids d issolved in plasma are proteins. Proteins perform some of the most important job s in the human body. While circulating throughout the body, the blood plasma also carries solid s that are not dissolved. There are three kinds of solid bodies in the blood: red cells, white cells, and platelets. Each performs one major task. The red cells c arry oxygen throughout the body. The platelets help to clot the blood. The white cells attack infection causing bacteria. When harmful organisms infect the body , the total number of white cells may double or triple. One of the ways a doctor can tell whether someone is suffering from some unknown infection is to count t he white cells in a tiny sample of blood.The blood looks red because of the g____of red cells.
37、(同36题)Besides the solid matters dissolved in the watery part, other kinds of solid matters s____in the blood.

38、(同36题)The function of blood lies in the fact that it c____ various nutrition to every part of the whole body.
