HUMAN BIOLOGY UNIT 4 MILESTONE How do blood vessels maintain homeostasis when blood pressure increases? • Vasoconstriction • Hypotension • Hypertension • Vasodilation CONCEPT Blood Pressure Which set of facts is true for vaccines? • They produce active immunity. They are mostly targeted against viruses. • They produce passive immunity. They are mostly targeted against viruses. • They produce active immunity. They are mostly targeted against bacteria. • They produce passive immunity. They are mostly targeted against bacteria. CONCEPT Vaccines Which statement is true about monoclonal antibodies? • They are used in the treatment of certain cancers. • They are used in the treatment of viral infections. • They are used in the treatment of bacterial infections. • They are used in the treatment of fungal infections. CONCEPT Organ Transplant and Immunotherapy Which of the following statements about immunodeficiency is true? • It only occurs when the immune system has been intentionally compromised as part of treatment for diseases like cancer. • It means the immune system attacks a person's own cells and organs. • It means the immune system is overactive and targets harmless things like pollen or dander. • It means the immune system is weak or nonexistent. CONCEPT Immune System Disorders and HIV/AIDS The diagram shows the structure of the human heart. What is the importance of the part labeled X? • It provides lubrication to the heart by secreting fluids. • It separates oxygenated blood from deoxygenated blood. • It prevents the backflow of blood from the pulmonary artery. • It prevents the backflow of blood from the systemic circuit. CONCEPT Heart and Blood Flow Which type of white blood cell attacks other unhealthy cells? • Eosinophils • Monocytes • Lymphocytes • Basophils CONCEPT White Blood Cells Which set of facts is true for the lymphatic system? • It works together with the circulatory and immune systems. It returns tissue fluid back to the cardiovascular system. • It works together with the circulatory and immune systems. It carries blood to the excretory system. • It works together with the respiratory and immune systems. It returns tissue fluid back to the cardiovascular system. • It works together with the circulatory and respiratory systems. It transports blood to the central nervous system. CONCEPT Lymphatic System What is "vital capacity?" • The maximum amount of air that moves out of the lungs after taking the deepest breath • The maximum amount of air that moves into the lungs after taking the deepest breath • The minimum amount of air that moves into the lungs after taking the deepest breath • The minimum amount of air that moves out of the lungs after taking the deepest breath CONCEPT Respiration and the Respiratory Cycle What muscular tubes, not supported by cartilage, help regulate airflow into and out of the lungs? • Diaphragm • Trachea • Alveoli • Bronchioles CONCEPT Lower Respiratory Tract A person with blood type A can donate blood to individuals with which blood types? • A, B • A, O, AB • A, AB • A, O CONCEPT Blood Types Which of the following is the contraction phase of the cardiac cycle? • Diastole • Cardiac output • Cardiac input • Systole CONCEPT Cardiac Cycle and Cardiac Conduction System Which accurately represents bloodflow through the cardiovascular system? • Heart → Arteries → Arterioles → Capillaries → Venules → Veins → Heart • Heart → Arterioles or Venules → Capillaries → Arteries or Veins → Heart • Heart → Arteries or Veins → Capillaries → Arterioles or Venules → Heart • Heart → Veins → Venules → Capillaries → Arterioles → Arteries → Heart CONCEPT Cardiovascular System Which statement correctly identifies the role of IgE, the membrane-bound antibody that anchors to a variety of different white blood cells? This antibody is a B-cell receptor that clusters into a structure with many binding sites in response to a pathogen. Found in tears and saliva, this antibody inhibits invading pathogens from binding to the body's cells. When this antibody binds to an antigen, it induces the attached cell to release histamines. Located in the blood, this antibody is the most prevalent in the human body. CONCEPT Humoral Immunity 14 Which part of the upper respiratory system is commonly known as the throat? Trachea Larynx Esophagus Pharynx CONCEPT Upper Respiratory Tract 15 What are the two types of effector T-cells? Helper T-cells and mediator T-cells Cytotoxic T-cells and phagocytic T-cells Helper T-cells and phagocytic T-cells Cytotoxic T-cells and helper T-cells CONCEPT Cell-Mediated Response 16 Which of these is a characteristic of adaptive immunity? It produces memory cells. • It is the first line of defense. • It does not recognize MHC. • It is non-specific. CONCEPT Adaptive Immunity What is "leukocyte" the technical term for? • Plasma • White blood cells • Red blood cells • Platelets CONCEPT Blood Which cells are triggered by our immune system to destroy certain types of cancer cells? • Plasma cells • Myeloma cells • Natural killer cells • Spleen cells CONCEPT Cancer and Homeostasis Which kind of immunity does mucus play a role in? • Innate • Physical barriers • General • Adaptive CONCEPT Pathogens In which of the following does the blood clot appropriately to prevent major blood loss? • Hemophilia • Hemostasis • Embolism • Thrombosis CONCEPT Platelets
