An explosion of knowledge was recently noted in the molecular biology and mode of replication of the influenza virus. From 1934 when the influenza virus was first isolated, it is the object of intensive research. The treatment of the influenza virus diseases is followed by the constant development of new drugs. Detailed reviews and explanations of clinical techniques were provided by the authorities in the special field. How does the human body stop the viruses in their massive multiplication? Two ways are mentioned. An infected cell releases an unknown substance. It affects other cells. They produce a protein, interferon. Interferon is not specifically produced to fight flu. Any virus infection is influenced by it. The second way is through the body's immune defence system. Large quantities of vaccine are prepared to inoculate high risk groups in the population. New preventive methods and drugs are devised and improved. Exercise 2. Answer the following questions.
Exercise 3. Translate the following sentences. Note that in English scientific articles sentences begin with it + verb in passive voice and are translated: it is said - говорять, що; it is thought - думають, що; it is known - відомо, що. 1. It is observed that effective measures are needed by doctors to treat viral diseases. 2. It is seen that unknown substances are released by an infected cell. 3. It is stated that immunoglobulin proteins are produced by the body. 4. It is noted that the body produces special immunoglobulins. 5. It is established that the use of preventive vaccines reduced the incidence of infectious disease. 6. It is known that doctors need effective preventive measures to eliminate virus diseases. 7. It is reported that virologists study the mode of replication of the influenza virus. 8. It is believed that a review of the literature helped the author's analysis of the data. UNIT SEVENTEEN

Exercise 5. Choose the correct answer to the question. What are the two main functions of the digestive system? a) The organs of the digestive system break the taken food into the smallest particles and supply body cells with nutrients to provide energy.
Exercise 6. Read the texts, translate them. Alimentary Tract The alimentary tract is a musculomembraneous canal about 8.5 m in length. It extends from the oral cavity to the anus. It consists of the mouth, pharynx, esophagus, stomach, small intestine, and large intestine. The liver with gall bladder and pancreas are the large glands of the alimentary tract. The first division of the alimentary tract is formed by the mouth. Important structures of the mouth are the teeth and the tongue, which is the organ of taste. The soft and hard palates and the salivary glands are also in the oral cavity. From the mouth food passes through the pharynx to the esophagus and then to the stomach. The stomach is a dilated portion of the alimentary canal. It is in the upper part of the abdomen under the diaphragm. It measures about 21-25 cm in length, 8-9 cm in its greatest diameter. It has a capacity from 2.14 to 4.28 1. The small intestine is a thin-walled muscular tube about 6.5 meters long. It is located in the lower and central portions of the abdominal and pelvic cavities. The small intestine is composed of the duodenum, jejunum, and ileum. The large intestine is about 1.5 m long. It is divided into cecum, colon and rectum. Accessor}' Organs The liver is the largest gland in the human body. It is in the right upper part of the abdominal cavity under the diaphragm. So, the liver is on the right side of the abdomen. The weight of the liver is 1500 g. The gall bladder is a hollow sac lying on the lower surface of the liver. The pancreas is a long thin gland lying under and behind the stomach on the left side. Exercise 7. Look at Fig. 17-1. Name all the organs of the digestive system from the oral cavity to the anus. Exercise 8. Say what organ is spoken about.
oral cavity (mouth) sublingual gland submandibular gland pharynx trachea (windpipe) esophagus *f stomach t diaphragm liver- gall bladder spleen common bile duct pancreas and ■ pancreatic duct ■ transverse colon duodenum * -small intenstine ascending colon - cecum - vermiform appendix -descending colon -sigmoid colon Fig. 17-1. The digestive system Exercise 9. Read the information about enzymes. Explain the role of enzymes. Enzymes are proteins that speed the rate of chemical reactions, but at the same time they are not themselves changed or used up in these reactions. An enzyme is a highly specific substance, it acts only in a certain type of reaction, involving a certain type of food molecule. For example, the carbohydrate-digesting enzyme amylase only splits starch into maltose. Another enzyme is required to split maltose inlo two molecules of glucose (monosaccharide). Other enzymes split fats into their building blocks, glycerol and fatty acids, and still others split proteins into amino acids. Exercise 10. Look at Table 17-1. Name all products secreted by the organs of the digestive tract and accessory organs. What are their actions? Table 17-1. Digestive Juices Produced by the Digestive and Accessory Organs

Exercise 6. Translate into Ukrainian.
III. Independent Work: Liver Exercise 1. Read the text, retell it. Liver The liver is the largest glandular organ of the body. It is located in the upper right part of the abdominal cavity under the dome of diaphragm. The human liver is the same reddish brown Fig. 17-2. The liver color as the animal liver seen in the supermarket. The liver has a large right lobe and a smaller left lobe. It has also a double blood supply: the portal vein and the hepatic artery. The hepatic artery carries oxygenated blood to the liver, and the portal vein carries blood that is rich in the end products of digestion (Fig. 17-2). The main functions of the liver can be listed:

They suffer from myocarditis, pericarditis, cardiosclerosis, etc. They have heart troubles, breathlessness, weakness and other symptoms. In the pulmonological department there are patients with lung diseases. They suffer from pneumonia, bronchitis, asthma, etc. They complain of their bad cough, high temperature, headache. In the gastroenterological department you can find patients with abdominal diseases. They have gastritis, colitis, ulcer, etc. They feel pain in their stomachs, weakness and sometimes they have vomiting or nausea. Many patients are recovering. Some of them are all right.

Скоро їх випишуть із лікарні. Exercise 7. Read, translate the text and make up a plan on it. Ulcers An ulcer (peptic ulcer) is a sore or a crater in the lining of the gastrointestinal tract. Ulcers may develop in the stomach (gastric ulcers) or in the upper part of the small intestine (duodenal ulcers). Ulcers develop when something damages the protective lining and allows stomach acid to eat away at it. Factors that increase the risk of ulcers include: - regular use of aspirin, ibuprofen, and other nonsteroidal anti-inflammatory drugs (NSAIDs), such as indomethacin, naproxen, clinoril, etc.;
Symptoms of an ulcer may include a burning or sharp pain in the abdomen between the navel and the end of the breastbone. The pain often occurs between meals and may wake the person during the night. The pain can usually be relieved by eating something or taking an antacid. Ulcers may also cause heartburn, nausea or vomiting, and a bloated or full feeling during or after meals. Ulcers can cause bleeding in the stomach, which may produce black or tarry bowel movements. Without treatment, ulcers may occasionally cause obstruction or break through (perforate) the stomach lining. Bleeding and perforation are serious situations that require immediate treatment. Home Treatment - Avoid foods that seem to bring on symptoms. It isn't necessary to eliminate any particular food from your diet (although milk and milk products slow healing and should be avoided).
- Stop smoking. People who smoke are twice as likely to develop ulcers as nonsmokers. Smoking also slows healing of ulcers.
