Textbook Question
Chapter 9, Problem 1CT
New research suggests a link between some microbes that normally live in the body and seemingly unrelated major illnesses. The gum disease called periodontitis itself is not life-threatening, for instance, but it is a fairly good predictor for heart attacks. Bacteria that cause gum disease can trigger inflammation. Thinking back to your reading in Chapter 7, how do you suppose that this response also may be harmful to the heart?

Are the 3 questions correct?
Tuberculosis is a disease that has been with us for a long time. Scientists believed that the disease was responding to treatment. However, in the past few years there has been an increase in the number of cases of tuberculosis. Explain the reason for this increase.
4) A patient has their spleen removed due to an accident. How will this affect the immune response?
5) You come in contact with staphylococci through a cut. What cellular features will the immune cells recognize?
6) Name two opsonins and how do these molecules help the immune response?
7) Fever is part of the inflammatory process. What is the role of fever during an immune response?
8) This chemical is used to induce anti-viral responses in cells to protect the cells from viral infections.

- Hay fever, also called allergic rhinitis, is a common ailment in the spring. People who experience hay fever have sensitive immune systems that respond to pollen in the air. When pollen, the allergen, enters the airways, the inflammatory response is triggered, even though pollen is not a dangerous molecule. Symptoms include inflammation of the airways, nasal congestion, and watery eyes. While there is currently no cure for hay fever, people suffering from it often take antihistamines, medications that inhibit the action of histamine. How would this help the condition?arrow_forwardPatients who have recently had a bone marrow transplant are extremely susceptible to infection. Why would this be so?arrow_forwardIn HIV, helper T cells are affected. Describe how this impacts both the humoral and cell- mediated immune system. Why would an ordinary cold virus be dangerous to an AIDS patient?arrow_forward
- Human rhinoviruses are a large family of related viruses responsible for many cases of the "common cold." They are naked, ss(+)RNA viruses. When a person gets a cold, most of the symptoms result from inflammation of the upper respiratory system, caused by the innate immune response to the virus. Describe how the innate immune system would recognize the presence of a rhinovirus infection, and then how its response could lead to cold symptoms.arrow_forwardA friend was recently diagnosed with strep throat. One week after his treatment, he redeveloped the infection. In conversation, your friend tells you, “I must have become immune to the drug the doctor gave me!” a. Discuss the validity of your friend’s statement, providing evidence in support of or refuting his claim. b. After further conversation, your friend tells you that he stopped taking his initial antibiotics after 2 days because he “felt 100% better.” Explain how this action might have played a role in the redevelopment of his infection. c. When he returned to his physician, she ordered a test to determine which antibiotic should be prescribed to treat his reinfection. Summarize a test that could be used to obtain this information.arrow_forwardPeople infected with SARS-Cov-2(the cornavirus that causes covid-19) can show an array of different symptoms and comlications. One complication occurs in the same patients is the development of blood clots throughout the body. Thevirus can infect endothelial cells. How are endothelia involved with blood clotting? If you were to design a pharmaceutical (medication) taht reduced blood clotting, how might it work? There are many ways to approach this question. Please mention at least one SPECIFIC REACTION in your explanation.arrow_forward
- The Mystery of Legionnaire's Disease -The bicentennial convention of the American Legion was held in Philadelphia in 1976 at the elegant but aging Bellevue Stratford Hotel. Toward the end of the conference, a number of the attendees were suffering from flulike symptoms, and 4 days after leaving Philadelphia, an Air Force veteran died from pneumonia. During the next week, 30 additional Legionnaires who had been at the conference died from what became known as Legionnaire's Disease. Theories ranged from viral pneumonia to terrorism (before this became a popular alternative) to a communist plot (after all, these were mostly veterans who died). Conduct a research and answer the following: a) find the cause of the Legionnaire's Disease; b) explain how this disease spread in the hotel and come into contact with the Legionnaires (attendees) c) explain how this event can be prevented in the future.arrow_forwardBryan is a physician at a major metropolitan hospital. Since the attacks of September 11, 2001, his hospital has been preparing for a terrorist attack.

Which major organ is affected and what are the consequences? Why does the blood pressure decrease in a person infected with Ebola virus? What leads to the death of the person? How many people died in the West African Ebola outbreak? How many healthcare workers died? What is being done to prevent Ebola virus?arrow_forwardIn Ingested poisoning and carbon monoxide poisoning, how does a person get this disease? Is it genetic? Is it contagious?arrow_forwardStatement 1: Phagocytosis is one of the mechanisms performed by multicellular organisms as a defense against invading microorganisms and also to remove old and/or damaged cells from the body. Statement 2: Some types of white blood cells in humans are professional phagocytes. A Both statements are true. Statement 1 is true. Statement 2 is false. Both statements are false.
