WBCs. / Leukocytes are colourless nucleated cell elements.. Larger and lesser in number.. Important in defence mechanism of body.. WBCs. . vs. RBCs:. Larger in size.. Irregular.. Nucleated.. S. 2. , & volume is . S. 3. , where . S. = length of the side of the cube.) Which of the following cube-shaped cells would be most efficient in removing waste by diffusion?. Cells (Test . 1). 5. . Cells in animals and plants have unique forms that allow each to take part in processes that are necessary for the cell and or/living thing to survive.. Cells. What is an organelle?. Organelles are to cells what organs are to the body. . some beneficial. some potentially disease causing. immune system . – not an organ system, but a population of cells that inhabit all of our organs and defend the body from agents of disease. especially concentrated in the true organ system – .

Th2 cells are characterized by the expression of the . transcription . factor GATA3 and produce cytokines: IL-4, IL-5, IL-6, IL-10, and IL-13. Th2 cells are associated with several inflammatory conditions, including allergy and asthma.. Natural . killer (NK) cells are large granular lymphocytes that, like CTLs, use cytoplasmic granules containing . perforins. to kill target cells. NK cells . were defined . initially by their ability to lyse certain tumor cell lines and virally infected cells in vitro. In contrast to T cells, NK cells can lyse these cells without prior immunization, and so mediate a form of innate (or natural) immunity that is termed . Cells are Basic to Life . The human body is composed of trillions of cells.. There are about 200 different types of cells. .
