Albumin - correct answer a plasma protein that helps regulate osmotic concentration of blood by drawing water into the capillaries Globulin - correct answer Plasma protein used to manufacture antibodies Fibrinogen - correct answer Plasma protein that functions in blood clotting Hemoglobin - correct answer Binds oxygen to aid in its transport to the body's cells Erythrocytes (Red Blood Cells) - correct answer Has no nucleus Erythrocytes (Red Blood Cells) - correct answer Described as enucleated biconcave disks Erythropoiesis - correct answer Process of making erythrocytes that occurs in the bone marrow Anemia - correct answer Condition caused by low levels of hemoglobin in the erythrocytes or a lack of erythrocyte production Anemia - correct answer Caused by a diet low in iron or blood loss Leukocytes - correct answer white blood cells Leukocytes (White Blood Cells) - correct answer Provide a defence against foreign invaders in the blood or tissues Thrombocytes - correct answer Platelets Fibrinogen - correct answer Converted by thrombin into fibrin threads Thromboplastin - correct answer Hormone released by platelets when they hit a torn blood vessel Prothrombin - correct answer Activated by thromboplastin to be converted into thrombin Liver - correct answer Structure where prothrombin and fibrinogen are manufactured Thrombus - correct answer A blood clot that seals a blood vessel so blood cannot get through Embolism - correct answer A dislodged blood clot that is carried by the circulatory system to a vital organ Glycoproteins - correct answer Markers found on the cell membrane of red blood cells O - correct answer Blood type that has neither the A nor B glycoproteins Antigen - correct answer A substance that stimulates the formation of an antibody Antibodies - correct answer Y-shaped proteins that are formed within the blood plasma in response to a foreign invader Agglutination - correct answer Blood clumping caused by antibody response O- - correct answer Universal donor AB+ - correct answer Universal recipient Rh (Rhesus) Factor - correct answer Antigen found in the blood of most people Erythroblastosis fetalis - correct answer A condition which can occur when an Rh- mother had developed Rh* antibodies and can enter the blood stream of her Rh+ fetus Erythroblastosis fetalis - correct answer Condition that can cause anemia, jaundice, and an enlarged liver Physical and chemical barriers - correct answer First line of defense Non-specific biological response - correct answer Second line of defense First line of defense - correct answer Skin, mucous lining, gastric acid, human tears Macrophages - correct answer Phagocytic leukocytes Phagocytic leukocytes - correct answer Attack and engulf invaders, destroying itself and the invader to create pus Pus - correct answer Protein fragments resulting from phagocytosis involving macrophages Third line of defence - correct answer Specific biological response Complement proteins - correct answer Plasma proteins that trigger the formation of a protective coating around the invader, immobilizing it Lymphocytes - correct answer Leukocytes that produce antibodies to destroy invaders T and B cells - correct answer Types of lymphocytes T-cells - correct answer Produced in the bone marrow and mature in the lymph nodes. Stored in the thymus gland Helper T-cells - correct answer ID antigen and make template Killer T-cells - correct answer Rupture infected cells Suppressor T-cells - correct answer Stops immune response when complete Memory T-cells - correct answer Store template for quick mobilization of immune response to re-infection Helper T-cells, killer T-cells, suppressor T-cells, memory T-cells - correct answer Order of T cells in immune response B-cells - correct answer Produce antibodies that complement the template from T-cells Vaccines - correct answer Substances that stimulate the body to produce antibodies for a particular foreign invader Allergies - correct answer Occur when the immune system mistakes harmless antigens for harmful invaders Anaphylactic reactions - correct answer Severe allergic reactions Histamine - correct answer Substance that is produced by basophils and mast cells T-cells - correct answer Produced in the bone marrow and mature in the lymph nodes. Stored in the thymus gland Renegade T and B cells - correct answer Created by failure of suppressor T-cells to control immune response Autoimmune diseases - correct answer Include type I diabetes, multiple sclerosis, and rheumatoid arthritis Stem ce
