1. Rheumatoid arthritis is an inflammatory disease affecting joint tissues. This disease is known to have an autoimmune compo- nent. Autoimmunity is an immune response inappropriately directed toward normal self-antigens. Many persons with rheu- matoid arthritis have rheumatoid factor (RF) present in their blood. RF is an abnormal antibody. Not all persons with the disease have RF in their plasma, and RF is known to be present in conditions other than rheumatoid arthritis. Based on this information and your previous study, outline a simple test to detect the presence of RF in plasma. If your test is used to screen for rheumatoid arthritis, does a positive result (i.e., RF is pres- ent) mean that the person definitely has the disease? Why or why not?
8.A friend tells you the following story. "My aunt just received a heart transplant. Her doctors warned us that her body might reject the tissue. I just can't understand how that could happen as human hearts are made of the same tissues, aren't they?" What could be your best possible response to this? Note: This is a multiple question, choose the correct answer below: "Yes, all human hearts are made of cardiac muscles. As far as the rejection issue, everyone has different MHC proteins on their tissues. Your aunt's immune system recognizes the ‘self' tissues but can cause tissue rejection because of the ‘nonself' tissue in her body having different MHC proteins." "Yes, all human hearts are made of cardiac muscles. As far as the rejection of tissues goes, your aunt might have different antibodies than did the donor, which could lead to a rejection." "Yes, all human hearts are made of cardiac muscles. However, your aunt might have been given some type of drug during the…

Which of the following is a FALSE statement? (Check all that apply) All granulocytes are from the myeloid lineage. B Fibrinogen plays a crucial role in blood clotting. The cardiovascular system includes the heart, blood vessels and lymphatic organs. When hypothalamic osmoreceptors are D) activated, more ADH is released from the anterior pituitary. The transport of hormones is one of the E regulatory functions of the blood. The secretion of hormones is one of the regulatory functions of the blood. Hemoglobin is the main protein found in the blood plasma. Thrombocytes are form from the fragmentation H of large cells called megakaryocytes. The blood leaving the heart enters an artery, the blood returns to the heart from a vein. Leucocytes cross the capillary wall by a process call dialysis.
