    Text 6. Blood


    1. Humans can't live without blood. Without blood, the body's organs couldn't get the oxygen and nutrients they need to survive, we couldn't keep warm or cool off, fight infections, or get rid of our own waste products. Without enough blood, we'd weaken and die.

    2. Two types of blood vessels carry blood throughout our bodies: The arteries carry oxygenated blood (blood that has received oxygen from the lungs) from the heart to the rest of the body. The blood then travels through the veins back to the heart and lungs, where it receives more oxygen.

    3. The blood that flows through this network of veins and arteries is called whole blood, and it contains three types of blood cells:

    1. red blood cells (RBCs)

    2. white blood cells (WBCs)

    3. platelets

    These blood cells are mostly manufactured in the bone marrow (the soft tissue inside our bones), especially in the bone marrow of the vertebrae (the bones that make up the spine), ribs, pelvis, skull, and sternum (breastbone).

    1. The cells travel through the circulatory system suspended in a yellowish fluid called plasma. Plasma is 90% water and contains nutrients, proteins, hormones, and waste products. Whole blood is a mixture of blood cells and plasma.

    2. Red blood cells (also called erythrocytes) are shaped like slightly indented, flattened disks. RBCs contain the iron-rich protein hemoglobin. Blood gets its bright red color when hemoglobin picks up oxygen in the lungs. As the blood travels through the body, the hemoglobin releases oxygen to the tissues.

    3. White blood cells (also called leukocytes) are a key part of the body's system for defending itself against infection. They can move in and out of the bloodstream to reach affected tissues. The blood contains far fewer WBCs than red cells, although the body can increase production of WBCs to fight infection.

    4. Several different parts of blood are involved in fighting infection. White blood cells called granulocytes and lymphocytes travel along the walls of blood vessels. They fight germs such as bacteria and viruses and may also attempt to destroy cells that have become infected or have changed into cancer cells.Certain types of WBCs produce antibodies, special proteins that recognize foreign materials and help the body destroy or neutralize them.

    5. Platelets (also called thrombocytes) are tiny oval-shaped cells made in the bone marrow. They help in the clotting process. When a blood vessel breaks, platelets gather in the area and help seal off the leak.

    6. Blood is essential for good health because the body depends on a steady supply of fuel and oxygen to reach its billions of cells. Even the heart couldn't survive without blood flowing through the vessels that bring nourishment to its muscular walls.Blood also carries carbon dioxide and other waste materials to the lungs, kidneys, and digestive system to be removed from the body.

    7. Blood cells and some of the special proteins blood contains can be replaced or supplemented by giving a person blood from someone else via a transfusion. In addition to receiving whole-blood transfusions, people can also receive transfusions of a particular component of blood, such as platelets, RBCs, or a clotting factor. When someone donates blood, the whole blood can be separated into its different parts to be used in this way.


    Write down the letter of the paragraph which

    describes the production of blood cells

    1 _____

    describes white blood cells’ fight against infection

    2 _____

    introduces the topic of the text

    G. Read Text 7 and complete the tasks below

    Text 7. Mouth and Teeth

      1. Your smile is often the first thing people notice when they look at you. Your facial expression attracts other people’s attention. With the help of the teeth your mouth shows a lot of emotions on your face from happiness to anger.

      2. The mouth also plays a key role in the digestive system, but it does much more than get digestion started. The mouth — especially the teeth, lips, and tongue — is essential for speech. The tongue, which allows us to taste, also helps us to form words when we speak. The lips both help to hold food in the mouth while we chew and pronounce words when we talk.

      3. With the lips and tongue, teeth help to form words by controlling air flow out of the mouth. The tongue strikes the teeth as certain sounds are made.

      4. The hardest substances in the body, the teeth are also necessary for chewing (or mastication) — the process by which we tear, cut, and grind food in preparation for swallowing. Each type of tooth serves a different function in the chewing process. Incisors cut foods when you bite into them. The sharper and longer canines tear food. The premolars, which are flatter than the canines, grind and mash food. Molars, with their points and grooves, are responsible for the most vigorous chewing. All the while, the tongue helps to push the food up against our teeth.

      5. During chewing salivary glands in the walls and floor of the mouth secrete saliva, which moistens the food and helps break it down even more. Saliva makes it easier to chew and swallow foods (especially dry foods), and it contains enzymes and lubricants that aid in the digestion of carbohydrates.

      6. Once food has been converted into a soft, moist mass, it's pushed into the throat (or pharynx) at the back of the mouth and is swallowed. When we swallow, the soft palate closes off the nasal passages from the throat to prevent food from entering the nose.

    Write down the letter of the paragraph which

    tells about the chemicals which help to digest food

    1 _____

    describes different expressions which your face shows

    2 _____

    describes particular sounds produced by the tongue and the teeth

    3 _____

    tells about both speech and digestion in which the mouth and its inner parts play a role

    4 _____

    tells about further food’s way from the mouth

    5 _____

    describes each tooth’s function in chewing

    6_____


    Decide whether the statements are true or false and put (T) or (F) next to the statement

    Teeth on their own are able to form words by controlling air flow out of the mouth.

    7 _____

    Molars do the most energetic work in chewing

    8 _____

    Saliva assists digestion of carbohydrates

    9 _____

    The tongue prevents food from entering the nose

    10 _____

    Text 8. HOW FLUORIDE WORKS

      1. Fluoride is a natural element that can be found in many things, like the water we drink and the food we eat. Decades ago, scientists began to notice that children who lived in places where fluoride occurred naturally in the water, had fewer dental cavities.

      2. Fluoride which is absorbed by your body is used by the cells that build your teeth to make stronger enamel. Topical fluoride - fluoride that is applied to the outside of the enamel - makes the crystals that form enamel more durable. Tooth enamel crystals that have fluoride are much more resistant to acid. They are less likely to breakdown and cause the tooth surface to become porous.

      3. If your dentist recommends a fluoride treatment during your next dental visit, you'll be receiving topical protection. The fluoride your dentist puts in your mouth will help make the crystals in your tooth enamel stronger. Always use a toothpaste with fluoride.

      4. Brushing your teeth is one of the most effective ways of keeping your teeth healthy Contrary to what you might think, a gentle brushing with a soft-bristle toothbrush is just as effective (and less damaging!) than a vigorous scrubbing with a stiff-bristle toothbrush

    Write down the letter of the paragraph which

    mentions scientists’ discovery of the connection between fluoride and dental cavities

    1 _____

    describes the effect fluoride produces on enamel

    2 _____

    advises what toothbrush to use

    3 _____

    tells about location of fluoride

    4 _____

    describes fluoride treatment your dentist uses

    5 _____

    Decide whether the statements are true or false and put (T) or (F) next to the statement

    Children who don’t get enough fluoride might have more dental cavities.

    6 _____

    Fluoride influences the crystals of the enamel making it stronger.

    7 _____

    It is very easy for acid to break tooth enamel crystal with a lot of fluoride.

    8 _____

    Gentle brushing with a soft-bristle toothbrush is no less effective than brushing with a stiff-bristle toothbrush.

    9 _____

    Dentists often recommend a fluoride treatment to their patients.

    10 _____
