Remember WBCs with percentage White blood cells (WBCs), also called leukocytes or leucocytes, are the cells of the immune system that are involved in protecting the body against both infectious disease and foreign invaders. All white blood cells are produced and derived from multipotent cells in the bone marrow known as hematopoietic stem cells. Leukocytes are found throughout the body, including the blood and lymphatic system. These broadest categories can be further divided into the five main types: neutrophils, eosinophils (acidophiles), basophils, lymphocytes, and monocytes.These types are distinguished by their physical and functional characteristics. Monocytes and neutrophils are phagocytic. #usmle #usmlestep1 #usmlestep2 #usmleprep #md #doctor #doctorsofinstagram #hospital #medicine #endocrine #surgeon #followforfollow #clinicals #surgery #medico #mbbs#medstudent#pathology #microbiology #anatomy #physiology #biochemistry #ent #gynaecology #obstetrics https://www.instagram.com/p/CAHHik6jH1e/?igshid=mgvz8yqkx5gn
