Explanation:
Central Nervous system:
CNS is the abbreviation of Central Nervous system. CNS controls the whole body functions so it is the most important component of the body. CNS consist of two parts 1) Brain and 2) Spinal cord
Both of these organs are very important and hence need to be protected. Nature provided these organs with certain protective mechanisms these includes
1) Skull and Vertebral column:
Skull is present around brain and vertebral column is present around spinal cord. These structure provides mechanical support to soft parts of CNS.
2) Meninges:
These are the membranes that provide antiseptic environment to the brain and hence protect it from microbes and other harmful substances.

The original phagocyte secretes cytokines that attract other phagocytes
Explanation:
Before phagocytosis occurs and with the presence of an original phagocyte at the scratch site mostly a macrophage (also a phagocyte), chemical signals signals are given off to attract phagocytes to the scratch site.
These chemical signals may be cytokines that are given off by macrophages located in the tissue near the infection site etc. These cytokines produced can then stimulate the recruitment of phagocytes including the neutrophils and monocytes from the blood.
