Welcome to your OCR AS Biology 6 Destruction of alveoli occur in the following disease. Bronchitis Pneumonia Asthma EmphysemaThe amount of air which passes in or out of the lungs during each cycle of quiet breathing. Tidal volume Expiratory reserve volume Inspiratory reserve volume Vital capacityWhat is the component in cigarette smoke which causes addictivity? Nicotine Ammonia Tar Carbon MonoxideWhich of the following is not a function of surfactant? Acts as a moisturizer. Restricts the constriction of alveoli. Reduces the surface tension on the alveolar surface. Facilitates the movement of blood.Which is not a main component of cigarette smoke? Tar Arsenic Carbon Monoxide NicotineWhich of the following occurs during the process of inspiration? Volume of the lungs is decreased. Pressure within the pleural cavity is increased. Pressure within the pleural cavity is reduced. External intercostal muscles relax.Which is not a cause for lung diseases? Smoking Air pollution Heart transplant Allergic reactionsSelect the correct statement regarding tar in cigarette smoke. Tar encourages the sweeping action of many cilia. Tar in cigarette smoke stimulates the secretion of mucus. Tar does not play a role in the mucus accumulation within the bronchioles. Tar increases the cleaning action of the ciliated epithelium that lines the airways.Which of the following digests small polypeptides? Carboxypeptidases Amylase Chymotrypsinogen RibonucleasesWhen breathing, air is filtered, warmed and moistened in this organ. Nose Lungs Larynx AlveoliBreathing in someone else's cigarette smoke is called ________ smoking. Active Passive Artificial FacilitatedWhich component of pancreatice juice digests undigested starch? Chymotrypsinogen Amylase Lypase TripsinogenWhich of the following disease could be linked to atmospheric pollution from vehicle, industrial emissions and tobacco smell? Syphilis Tuberculosis Obstructive pulmonary diseases JaundiceWhat is chyme? A thick semifluid mass of partially digested food and digestive secretions. A mixture of digestive juices and hormones. An acid produced in the stomach. A hormone________ catalyzes the conversion of trypsinogen to trypsin. Enterokynase Carboxypeptidase Chymotrypsin LypaseWhat happens when the blood enters the artery with high pressure? Artery becomes wider, reducing the pressure a little. Wall of the artery recoils inwards. The blood flows back outwards. Artery increases the pressure even more.Select the correct sentence regarding smoking. The World Health Organization (WHO) considers smoking to be a disease. Manufacture of tobacco began after the cigarettes. Women started smoking at the end of 18th century. Tobacco was smoked until the end of 20th century.Which of the following is not an adaptation of alveoli for efficient gas exchange? Rich blood supply High number of alveoli Extremely thin walls Dry wallsSelect the correct sequence of steps regarding inspiration. a) Air pressure in the lungs decreases. b) Air flows into the lungs. c) Volume of the lungs increases.d) Diaphragm muscles contract. d, c, a, b d, a, c, b c, a, d, b a, c, b, dTime is Up!
