Monocytes are one type of white blood cell, and they are seen when a white blood cell differential test is conducted. A high absolute monocyte count may be the result of several different factors and usually requires further testing to determine the cause.Know More
A high absolute monocyte count can be the result of a viral infection such as mononucleosis or measles. Acute stress and autoimmune diseases may raise the level of monocytes in the differential. Parasites can also cause an increased monocyte count. In some cases, a more serious disease may be indicated, such as tuberculosis, chronic inflammatory disease or leukemia. Chronic bowel disease, heart infections and rheumatoid arthritis may be indicated if a high absolute monocyte count is noted on blood work. A bone marrow biopsy is usually performed if blood testing doesn't reveal the source of the increased monocytes.
Monocytes are made in the bone marrow of all bones. They account for approximately 1 to 10 percent of all the white blood cells found within the body. After monocytes enter the bloodstream, they eventually end up in the spleen, where they transform into macrophages. Macrophages rid the body of debris and old cells and help regulate the immune responses of the body.Learn more about Biology
Relative age allows scientists to know whether something is older or younger than something else, while absolute age means that scientists know the exact number in years that have passed since the object was created. Relative age will require the comparison of two or more objects, whereas absolute age does not.Full Answer >
High monocyte levels in the blood are referred to as monocytosis, states MedFriendly. Monocytosis may have a common cause such as inflammation, stress or a fever from a virus. It also may be caused by something more complex and potentially more serious.Full Answer >
Because they are the energy-producing organelles in plant and animal cells, a high number of mitochondria implies that the cell requires a great deal of energy to perform its specific function. Skeletal muscle cells, for example, have a large number of mitochondria because they are required to respond quickly when they are needed to do mechanical work. Fat cells also contain many mitochondria because their function is to store energy for when it is required by the body.Full Answer >
Potatoes lose weight when placed in high concentration sucrose solutions because they lose water through osmosis. Osmosis is the process where solvent molecules pass through semi-permeable membranes to equalize the solute concentration on both sides of the membrane.Full Answer >
