The photomicrograph shows polymorphonuclear leukocytes responding to a bacterial pneumonia. A Hemorrhage B Hemostasis C Neutrophil margination D Vasoconstriction E Vasodilation The answer is E: Thromboxane A2. Kallikrein and kinins choice D are formed following tissue trauma and mediate pain transmission. Phagocytic cells in this patient's affected lung tissue generate bacteriocidal hypochlorous acid using which of the following enzymes? The most potent chemotactic factors for leukocytes at the site of injury are 1 complement proteins e. This patient with viral myocarditis will show an accumulation of lymphocytes in the affected heart muscle. Leukotrienes stimulate contraction of smooth muscle and enhance vascular permeability.
The antimitochondrial antibody test is positive. This powerful oxidant is a major bactericidal agent produced by phagocytic cells. Diagnosis: Systemic lupus erythematosus A 25-year-old woman presents with a 2-week history of febrile illness and chest pain. Naïve lymphocytes encounter antigen-presenting cells macrophages and dendritic cells in the secondary lymphoid organs. None of the other choices mediate hemolysis. It is the equivalent of pus.
A Cadherin B Entactin C Integrin D Laminin E Selectin The answer is B: Constriction of precapillary arterioles. Diagnosis: Septic shock An 80-year-old woman presents with a 4-hour history of fever, shaking chills, and disorientation. In addition, the arachidonic acid metabolite thromboxane A2 plays a key role in the second wave of platelet aggregation and mediates smooth muscle constriction. A Complement proteins B Defensins C Kallikrein D Kinins E Prostaglandins The answer is D: N-formylated peptides. A Chemotaxis B Diapedesis C Haptotaxis D Margination E Phagocytosis The answer is E: Lysosomal enzymes. If someone with copyrights wants us to remove this content, please contact us immediately.
Sputum cultures are positive for Gram-positive diplococci. The other choices are extracellular matrix molecules that maintain tissue architecture and facilitate wound healing. Platelet degranulation is associated with the release of serotonin, which directly increases vascular permeability. Among these mediators are leukotrienes, also known as slow-reacting substances of anaphylaxis. She uses an intrauterine device for contraception. A Eosinophilia B Leukopenia C Lymphocytosis D Neutrophilia E Thrombocythemia The answer is C: T lymphocytes.
Twenty-four hours later, endothelial cells at the site of injury release a chemical mediator that inhibits further platelet aggregation. The patient subsequently develops acute bronchopneumonia and dies. Byrd Health Sciences Center in Morgantown, West Virginia. Â This textbook will enable students to identify and clarify specific, high-yield information frequently tested in anatomy and embryology courses and board examinations. Diagnosis: Acute mastitis A 22-year-old woman nursing her newborn develops a tender erythematous area around the nipple of her left breast.
Diagnosis: Acute mastitis A 22-year-old woman nursing her newborn develops a tender erythematous area around the nipple of her left breast. Microscopic examination of the lungs at autopsy is shown in the image. Intravascular thrombolysis that occurred in this patient was mediated by plasminogen activators that were released by which of the following cells? She has no history of trauma and no familial history of joint disease. A Complement proteins B Fibrin split products C Immunoglobulins D Interleukin-1 E Lysosomal enzymes The answer is D: a2-Macroglobulin. They are responsible for the development of many of the clinical symptoms associated with asthma and other allergic reactions. The other cells do not form multinucleated giant cells in granulomas.
We hope that you people benefit from our blog! The most common defect is iatrogenic neutropenia secondary to cancer chemotherapy. Within each of the four sections, chapters are organized around common health problems. Online access to the questions and answers on a companion website provides flexible study options. After leukocytes have come to a rest, integrins choice C mediate transendothelial cell migration and chemotaxis. End Chapter Exercises may differ. A Interferon-γ B Interleukin-1 C Platelet-derived growth factor D Transforming growth factor-β E Tumor necrosis factor-α The answer is E: Suppurative inflammation. This powerful oxidant is a major bactericidal agent produced by phagocytic cells.
She has a history of allergies and upper respiratory tract infections. A Decreased intravascular hydrostatic pressure B Decreased intravascular oncotic pressure C Increased capillary permeability D Increased intravascular oncotic pressure E Vasoconstriction of arterioles The answer is B: Hageman factor. Cadherins choice A mediate cell-cell adhesion, but they are not involved in neutrophil adhesion to vascular endothelium. The characteristic pulmonary lesions of simple coal worker's pneumoconiosis include nonpalpable coal-dust macules and palpable coaldust nodules, both of which are typically multiple and scattered throughout the lung as 1- to 4-mm black foci. Activation of the complement cascade by the classical or alternative pathway leads to the cleavage of complement fragments and the formation of biologically active complexes.
The other choices are not features of acute viral infections. We highly encourage our visitors to purchase original books from the respected publishers. Eosinophils contain leukotrienes and platelet-activating factor, as well as acid phosphatase and eosinophil major basic protein. Diagnosis: Asthma An 8-year-old girl with asthma presents with respiratory distress. The other choices do not regulate active hyperemia. .
