Red blood cells contain haemoglobin, carry oxygen from lungs to tissues and facilitate transport of CO 2 back to the lungs. Stem cells in the bone marrow are responsible for … This means the cell can be packed with haemoglobin, the oxygen carrying pigment. Their primary function is to destroy bacteria. White blood cells are blood components that protect the body from infectious agents.Also called leukocytes, white blood cells play an important role in the immune system by identifying, destroying, and removing pathogens, damaged cells, cancer cells, and foreign matter from the body.. Leukocytes originate from bone marrow stem cells and circulate in blood and lymph fluid. Neutrophils. Most of the functions of WBCs are performed within tissues located external to blood vessels. Highly differentiated for their specialized functions, they do not undergo cell division (mitosis) in the bloodstream, but some retain the capability of mitosis. Whenever a germ or infection enters the body the white blood cells have a variety of ways by which they can attack. Some WBCs destroy pathogens and cellular debris by phagocytosis. A healthy person’s WBC count is typically 4,500 to 10,000 per ul of blood. Neutrophils, like all other blood cells, are formed from the stem cells in the bone marrow. Author links open overlay panel Barbara J. Bain. All white blood cells are produced and derived from multipotent cells in the bone marrow known as hematopoietic stem cells.

White Blood Cells (WBC) White blood cells are responsible for fighting foreign pathogens (such … ; Monocytes – main action against bacterial infections. Neutrophils are attracted by chemicals released from damaged tissues and are the first WBCs to respond to tissue damage. See table 11.1 and figure 11.5. There are 5 main types: Neutrophils – main action against bacterial and fungal infections. White blood cells are typical animal cells and have all the regular cell organelles. The two cells differentiate entirely in terms of their function and structure. Neutrophils are a type of white blood cell with multi-lobed nuclei and stainable cytoplasmic granules. 3.) They release histamine and heparin when tissues are damaged and in allergic reactions. leukocytosis. They are characterized by a bilobed nucleus and red-staining cytoplasmic granules.
