Ground nesting bees in your backyard! Ground nesting bees in your backyard! Not all bees live in hives like honey bees do. In fact, 70% of all the 20,000 species of bees nest under ground. In North America, most of these ground bees become active in early spring.
Monocytes share the vacuum cleaner (phagocytosis) function of neutrophils, but are much longer lived as they have an additional role: they present pieces of pathogens to T cells so that the pathogens may be recognized again and killed, or so that an antibody response may be mounted.
A monocyte is a type of white blood cell that is produced by the bone marrow and helps to protect the body from foreign invaders, such as harmful bacteria and viruses. When there is a decreased number of monocytes in the blood, the body is more susceptible to illness.ome of the most common causes of a low monocyte count are illnesses that affect the bone marrow, such as HIV, rheumatoid arthritis, or lupus. A low monocyte count may be caused by a vitamin deficiency.
