On the basis of their appearance under a light microscope, white cells are grouped into three major classeslymphocytes, granulocytes, and monocyteseach of which carries out somewhat different functions. The more we learn about neutrophils, the wider their range of functions. T and B cells most often require activation by APCs, although some B cells can self-activate. Around 75% of white blood cells are phagocytes, these are the cells which phagocytose ('cell eating'). There are five different types of white blood cells, including neutrophils, lymphocytes, monocytes, eosinophils and basophils. Monocytes patrol the body looking for damaged cells and pathogens. Corrections? When refering to evidence in academic writing, you should always try to reference the primary (original) source. Oxygen is obtained as a result ofrespiratory systemactivity. As more red blood cells enter blood circulation, oxygen levels in the blood and tissues increase. Neutrophils move via diapedesis and only live for a few days. Blood is made up of four components: red blood cells - these transport oxygen around the body white blood cells - these fight infection platelets - these clot to prevent blood loss. While dendritic cells are not phagocytes, they are known to nibble cells, removing and digesting part of the membrane and so killing the cell. WBCs move by ameboid movement, a motion characterized by flowing extensions of cytoplasm that pull the cell along. When the kidneys sense the increase in oxygen levels in the blood, they slow the release of erythropoietin. The lymphatic system does different things: it acts as a one-way drainage system - this means it moves fluid from body tissues into the blood circulation it contains white blood cells called lymphocytes, which fight infection it gets rid of any waste that cells make.
