Concept explainers
To predict: The changes that occur when no NK cells are present in the body.
Concept introduction: A complex network of cells, tissue, and organs that work collectively for the protection of body and fight against the pathogens or foreign substances is called the immune system. Immune cells are the cells that actively participate in the defense mechanism initiated by the immune systems. One such major type of immune cells is lymphocytes.

- What change occurs to the adult lymphatic system as we getolder?a. The body produces and transports less lymph.b. Greater numbers of B-lymphocytes are produced.c. Helper T-lymphocytes do not respond as well to antigens.d. The lymph nodes enlarge.arrow_forwardHow are innate lymphoid cells, including natural killer cells, distinguished from lymphocytes? a- stimulation by pathogen associated molecular patterns b- single lobed nucleus c- production of cytokines d-expression of rearranged antigen receptorsarrow_forwardSome individuals are immune-compromised because their bodies do not make enough T-cells. What is the difference between a T-cell and any other cell type in the body? a. T-cells have different genomes than cells of other types b. T-cells have different genes than cells of other types c. T-cells have different proteins than cells of other typesarrow_forward

A.Macrophage B.T cell C.B cell D.Neutrophilarrow_forwardWhat would happen in the human body if there were no lymphatic system?arrow_forward
- Under what circumstances might NK cells kill our own cells?arrow_forwardCells called histiocytes are specialized phagocytes which remain within certain tissues. O 1) True O 2) Falsearrow_forwardWhich large lymphatic organ purifies blood by removing dead red cells, stores blood, and helps the immune system to recognize and attack foreign materials or proteins? a spleen b intestine c appendix d kidneyarrow_forward
