An associate degree is an undergraduate academic degree awarded by colleges and universities upon completion of a course of study intended to usually last two years. It is considered to be a greater level of education than a high school diploma or GED. The first associate degrees were awarded in the U.K. in 1873 before spreading to the U.S. in 1898. They have since been introduced in a small number of other countries.
Monocytes are the largest of the white blood cells. These are the cells that 'clean up' our blood the most. Monocytes also employ phagocytosis to 'eat' foreign particles, bacteria and dead neutrophils.
White blood cells (WBCs) There are five different types of white blood cells: lymphocytes, neutrophils (also called granulocytes), eosinophils, basophils, and monocytes. Each plays a different role in protecting the body from infection. Neutrophils, basophils and eosinophils kill and digest bacteria.
