Several types of cells in the immune system engulf microorganisms via phagocytosis. 1  Neutrophils. 2  Neutrophils are abundant in the blood, quickly enter tissues, and phagocytize pathogens in acute inflammation. 3  Macrophages. 4  Macrophages are closely related to monocytes in the blood.
Snowfall in Flagstaff ranged from 5 inches to 9 inches, with 8.6 inches at Flagstaff Pulliam Airport. Official record-keeping on Flagstaff's weather began on September 9, 1898, and a 30-year period ending in 2000 has been used in the last decade to determine what is average weather-wise.
In that case, the 30-year average for the city's snowfall is 109 inches, or 9 feet, due partly to heavy snow years in the 1970s and 1980s. Tallying all the winters since 1899, the area averages 7 feet of snow per winter -- about 84 inches. Flagstaff last beat both averages in the winter of 2004-2005.
