Arugula is also a good source of vitamin A, which is important for maintaining good vision, cell growth and immune function, with each serving providing 475 international units of vitamin A, or 10 percent of the recommended daily amount.
Neutrophils are white blood cells that serve as important phagocytes, or garbage collectors. There are about 100 billion of these cells produced every day in the bone marrow and they account for about 70% of the white blood cells in circulation in your body.
Special stem cells in the bone marrow give rise to neutrophils, also known as polymorphonuclear leukocytes or PMNs. Neutrophils are normally the most abundant white blood cells (WBCs) in the circulation, accounting for roughly 50 to 70 percent. Phagocytosis is the primary function of neutrophils, and they are highly effective and efficient at performing this role.
