Biology 234 PT3 Flashcards

The formation of carbonic acid inside the RBC is enhanced by the enzyme: * carbonic hemoglobin * lymph anhydrase * axillary anhydrase * carbonic anhydrase

Which of the following would be a form of CO₂ in the blood, plasma and cells? * HCO₃ * CO₂ dissolved in plasma * Carbamino hemoglobin

The blood hydrostatic pressure at the arterial end of the capillary bed, under normal conditions cuses the net movement of fluid: * out of the capillary bed at the arterial end * into the capillary bed at the arterial end * out of the capillary bed at the venous end

The pressure that has the primary responsibility for the movement of fluid into the capillary bed at both the arterial and the venous end is: * blood hydrostatic pressure * interstitial fluid osmotic pressure * blood osmotic pressure * interstitial fluid hydrostatic pressure

Mechanisms of antibody antigen interaction include inactivation by: * neutralization * agglutination * precipitation * complement protein activation

Respiratory system diseases include: * lung cancer * tuberculosis * emphysema

Increasing P CO₂ levels and or decreasing pH will: *shift the O₂ / Hgb curve to the lef to inhibit the unloading of oxygen * shif the O₂ / Hgb curve to the right to aid in the unloading of oxygen * have not effect on the curve * shift the curve firt to the right then to the lef as the temperature increases

Carbon dioxide transport is slightly more complex than oxygentransport. Which of the following correctly deccribes mechanisms of CO₂ transport? * 20% of CO₂ is carried dissolved directly into the plasma * 7-8% of CO₂ is carried in the form of carbamino hemoglobin * carbonic anhydrase is responsible for bonding CO₂ to hemoglobin

The movement of bicarbonate ion into the RBC is known as the_____ shift and is balanced by the movement of _____. * buffer , sodium * chloride , sodium * chloride , chloride * buffer , chloride

Pulmonary function tests (PFT) include measurements of: * vital capacity * expiratory reserve volume *hour respiratory volume

1) _____ used to produce the hemoglobin molecule in the RBC 2) _____ wave like propelling movements, with bacterial infection can become spasmodic 3) _____ secreate anti microbial substances that prevent excess growth of bacteria and molds 4) _____ needed for absorption of vitamin B12 in small intestine * intrinsic factor * salivatry gland * peristalsis * Iron (Fe)

A) if the item on the lft is greate than the itme on thr right B) if the item on the right is greater than the item on the left C) if the two are equal or nearly equal 1) _____ partial pressure of O₂ in an systemic artery<=>P O₂ in alveolar air 2) _____ alveolar air P CO₂ <=> venous blood P CO₂ 3) _____ size of thoracic cavity / diaphragm contracted <=> sixe of thoracic cavity / diaphragm relaxed 4) _____ O₂ concentration in pulomary artery <=> O₂ concentration in the pulmonary veins 5) _____oxygen concentration in systemic tissues <=> oxygen concentration in arterial blood

1) _____ immune system, specific response to disease 2) _____ phagocytes, neutrophils and macrophages 3) _____ body membranes, mechanical barriers 4) _____ disease causing microorganisms 5) _____ foreign substances, non self material * first line of defense * second line of defense * third line of defense * pathogens * antigens

Antibodies are caracterized by all of the following: * protein structure, composed of polypeptide chain * antigen-specificity, binding region for antigens * composed of constant and variable regions * different types exist: lgA, lgD, lgE, lgG, and lgM

Passive immunity involves: *short-term immune protection via antibodies * infusion of immune serum, (gama globulins) from exogenous source * passage of lgG antibodies from a pregnant mother to her fetus
