2. One of the forewings of a true bug, having a hard, thick basal portion and a thinner, membranous apex.
3. One of the partially thickened anterior wings of certain insects, as of many Hemiptera, the earwigs, etc.
2. A pathology in which iron accumulates in the tissues; characterized by bronzed skin and enlarged liver and diabetes mellitus and abnormalities of the pancreas and the joints; also known as, iron-storage disease, iron overload, bronzed diabetes.
Hemochromatosis, the most common form of iron overload disease, is an inherited disorder that causes the body to absorb and store too much iron. The extra iron builds up in organs and damages them. Without treatment, the disease can cause these organs to fail.
Iron is an essential nutrient found in many foods. The greatest amount is found in red meat and iron-fortified bread and cereal. In the body, iron becomes part of hemoglobin, a molecule in the blood that transports oxygen from the lungs to all body tissues.
Healthy people usually absorb about ten percent of the iron contained in the food they eat to meet the body needs. People with hemochromatosis absorb more than the body needs. The body has no natural way to rid itself of the excess iron, so it is stored in body tissues, especially the liver, heart, and pancreas.
2. A series of interconnected spaces between tissues and organs through which blood flows freely, unconfined by veins or arteries, occurring in several invertebrate groups; especially, mollusks and arthropods.
2. Blood cell, associated with a haemocoel, particularly those of insects and crustacea.
Despite the name, they are more like a leucocyte, being phagocytic and involved in defence and clotting of haemolymph and not involved in the transport of oxygen.
2. A device used in manual blood counts, consisting of a microscopic slide with a depression whose base is marked in grids, and into which a measured volume of a sample of blood or bacterial culture is placed and covered with a cover glass.
The number of cells and formed blood elements in the squares is counted under a microscope and used as a representative sample for calculating the unit volume; also called, counting cell, counting chamber, and hemocytometer.
2. Disintegration of the blood corpuscles by means of pressure.
