Chapter 22: Self-Quiz Which of the following is not an important function of the vertebrate circulatory system? transport of nutrients and respiratory gases regulation of body temperature protection of the body by circulating antibodies removal of waste products for excretion from the body defense against blood loss, through clotting What event initiates blood clotting? contact with an irregular surface by platelets and other factors in plasma production of the enzyme thrombin conversion of fibrinogen into fibrin conversion of fibrin into fibrinogen excess flow of blood through a capillary The sites of waste, nutrient, gas, and hormone exchange between the blood and body cells are the arteries arterioles capillaries veins all blood vessels What produces systolic blood pressure? contraction of the right atrium contraction of the right ventricle contraction of the atria contraction of the ventricles the pause between heartbeats Which of the following is not a component of plasma? water globulins fibrinogen albumins platelets Lymph most closely resembles which of the following? blood urine plasma interstitial fluid Water Blood going from the heart to the pulmonary artery passes through ________ valve. an atrioventricular a semilunar the bicuspid the tricuspid there is no valve there. Which sentence best describes the rhythmic beating of the heart? All four chambers contract together, then relax. Atria contract, heart is at complete rest, then ventricles contract. Ventricles contract, atria contract, heart is at complete rest. Atria contract, ventricles contract, heart is at complete rest. Right atrium and right ventricle contract together, left atrium and left ventricle contract, heart is at complete rest. Approximately 99% of blood cells are involved in immunity transporting oxygen eating invaders amoeba-like activities entering and leaving the bloodstream Athletes, such as long-distance runners, like to train at high altitudes because the lack of oxygen stimulates the_________________________. body to produce more lung tissue bone marrow to make more erythrocytes muscles to contract aerobically muscles to contract more strongly capillaries to diffuse oxygen more readily All of the following are true of lymph nodes except: destroy bacteria and viruses aid in clotting produce certain white blood cells are located along lymphatic vessels are filled with channels through which the lymph is forced With which other system do specialized respiratory systems most closely interact in exchanging gases between the cells and the environment? skin excretory system circulatory system muscular system nervous system The gas-exchange portion of the human respiratory system is the larynx trachea bronchi pharynx alveoli How is most of the oxygen transported in the blood? dissolved in plasma bound to hemoglobin in the form of CO2 as bicarbonate dissolved in water Which of the following statements regarding cigarette smoking is true? Cigarette smoke damages the alveoli. Cigarette smoke decreases the amount of oxygen in the blood. Cigarette smoke causes many types of cancer. Cigarette smoke can lead to heart damage. all of the above Why do respiratory systems and circulatory systems use bulk flow rather than diffusion for moving gases over long distances? Diffusion cannot move enough gas. Diffusion is too slow. Bulk flow requires energy. Diffusion requires energy. Diffusion never occurs over long distances, because it requires too much energy. After passing through the nasal cavities, incoming air moves next to the larynx trachea pharynx bronchi bronchioles A thin slice of a lung would look like a thin slice through a blown-up balloon of a piece of wood of the heart at the level of the ventricles of sponge cake of carrot The cells lining the conducting portion of the human respiratory system secrete mucus blood tissue fluid hormones enzymes When blood is drawn from a blood vessel in your arm, it is dark maroon-red in color. This indicates that it was taken from an artery was going away from the heart was taken from a vein was on its way to the tissues of the arm has just come from the lungs What is the approximate surface area for gas exchange in human lungs? 10 square feet 100 square feet 200 square feet 500 square feet 800 square feet Designed in cooperation with Andrew Stull and Steven Brunasso.
