Question

Helper T cells are able to stimulate which of the following cells to attack a specific viral antigen? A) phagocytic cells B) natural killer cell C) B cell D) Cytotoxic T cells E) all of these Mature B cells that have been activated to reproduce into large clones and now produce large amounts of a specific antibody are known as A) macrophages B) stem cells C) antigen receptors D) plasma cells E) antigen presenting cells The group of small Lymphatic organs throughout the body where many types of leukocytes may be found that clean out lymph carried by lymphatic vessels are known as ____ A) lymph nodes B) spleen C) tonsils D) thymus Helper T cells are able to recognize and before activated by the self-nonself antigen complex on the surface of antigen presenting cells (APC's). A) true B) false The second, much larger cloning of B Cells which occurs during a secondary immune response from same foreign antigen exposure later in a person's life is from ____ A) native B cell B) native T cell C) memory B cell D) memory T cell E) helper T cell Nitrogenous waster are eliminated as a results of protein and nucleic acid breakdown. What nitrogenous waste product is used for this process by mammals? A) urea B) ammonia C) uric acid D) nitrogenous bases E) all of these In the kidney, most water is initially removed from the blood in this part of the nephron? A) glomerulus B) proximal tubule C) loop of Henle D) distal tubule E) collecting duct After most water, salt, nutrients and HCO is initially replaced from the first region of the nephron to nearby capillaries, this "long descending thin walled tubule" replaces even more water and salt into its surrounding capillaries. A) glomerulus B) proximal tubule C) loop of Henle D) distal tubule E) collecting duct Where is urine finally stored in the Urinary system prior to elimination from the body? A) kidney pelvis B) medulla C) cortex D) ureters E) urinary bladder Antidiuretic hormone (ADH), which is actually synthesized in the hypothalamus of the brain and passed to and stored in the posterior pituitary, affects which organ that retains water to the circulatory system? A) urinary bladder B)liver heart D) ureter E) kidney Some drugs, poisons, H^+ and K^+ ions are added to the kidney filtrate (the eventual urine) in the proximal or distal kidney tubules. A) true B) false Autoimmune disorders are "under-reactions" of the immune system whereas Immunodeficiency disorders result when the immune system turns against some of the body's own molecules. A) true B) false Multipotent stem cells in the bone marrow are stem cells that give rise to two different stem cells (Lymphoid & Myeloid) that produce all of our blood cells. A)true B) false The Heimlich maneuver is used to remove food obstructions in our airways. A) true B) false The liver secretes digestive enzymes directly into the alimentary canal (digestive tract). A) true B) false When finished, hand your Scantron & Question to me up in front of the room and the room immediately!

Explanation / Answer

16. The correct option is d because cytotoxic cells are T cells that recognize infected cells, particularly from viruses.

17. The correct option is d plasma cells because these cells get activated during the immune secondary response.

18. The correct option is A because the lymph nodes are responsible for the digestion of the cellular debris and produce lymphocytes and filter the lymph flowing through it.

19. The correct option is true

20. The correct option is c because the human nitrogenous waste includes all of these.

21. The correct option is a that is glomerulus.
