Hematidrosis
Hematidrosis is a medical condition characterized by bleeding or spots of blood on the skin, often caused by severe physical or emotional stress, anxiety, or certain medical conditions, such as porphyria or HELLP syndrome. The term comes from the Greek words "haima" meaning blood and "idrosis" meaning sweating, and is a rare but recognized medical phenomenon.
Hematin
Hematin is a greenish-yellow pigment derived from hemoglobin, the protein in blood that carries oxygen. It is formed when hemoglobin is broken down or oxidized, typically in a process called denaturation. Hematin is often found in the liver, spleen, and kidneys after these organs have filtered the blood and removed old or damaged red blood cells.
Hematinic
Hematinic refers to a medicine that is used to treat or prevent anemia, which is a condition characterized by a lack of red blood cells or hemoglobin in the blood. Hematinics are designed to increase the production of red blood cells and hemoglobin, and may be prescribed to treat a variety of conditions, including iron-deficiency anemia, vitamin deficiency anemia, and anemia caused by chronic diseases such as kidney disease or cancer. Common types of hematinics include iron supplements, vitamin B12 supplements, and folic acid supplements.
Hematinometric
Hematinometric: Relating to the measurement of the color of blood or of hematin, a pigment found in blood.
Hematite
Hematite is a mineral composed of iron oxide (Fe2O3). It is a dark gray to reddish-black substance and is one of the most common iron ore minerals. It is often found in igneous and metamorphic rocks, and is also used as a pigment in paints and cosmetics. Iron ore is used to produce iron, which is a key component in many industries such as steel production and construction.

Hematocelia
Hematocelia is a rare medical condition characterized by the presence of blood in the fallopian tubes or other parts of the reproductive tract. It is usually caused by a blockage in the flow of menstrual fluid, which can accumulate in the fallopian tubes and be mistaken for blood. If left untreated, hematocelia can lead to infertility or ectopic pregnancy.
Hematochezia
Hematochezia is a medical term that refers to the passage of red or blood-tinged stools, which can be a sign of gastrointestinal bleeding or an underlying gastrointestinal disorder. It can be a symptom of various conditions, including inflammatory bowel disease, diverticulitis, gastrointestinal tumors, or gastrointestinal tract injuries. Hematochezia is considered a symptom rather than a diagnosis, as it can have multiple causes, and a thorough medical evaluation is necessary to determine the underlying cause.
Hematochromatosis
Hematochromatosis is a rare genetic disorder that affects the body's ability to process iron, leading to excessive accumulation of iron in the body, particularly in the liver, liver cells (hepatocytes), and Kupffer cells, which can cause organ damage, particularly liver cirrhosis, and other symptoms such as joint pain, skin changes, and eye problems. It is also known as bronze diabetes because of the bronze-like pigmentation of the skin that can occur in severe cases.
Hematochrome
Hematochrome refers to a type of pigment that is responsible for the red or yellow coloration found in certain algae, bacteria, and other organisms. It is a specialized type of chlorophyll pigment that is capable of producing bright red, orange, or yellow colors under certain conditions. Hematochrome particles are often found in freshwater environments and are used by some organisms as a protection mechanism against light damage or as a means of attracting mates.
Hematocrit
Hematocrit is a medical term that refers to the percentage of red blood cells in a person's blood. It is a measure of the proportion of red blood cells in a sample of blood, with normal values ranging from 40 to 54% for adult men and 37 to 48% for adult women. Hematocrit is used to diagnose and monitor conditions such as anemia, polycythemia, and certain types of bleeding disorders.
Hematocrya
Hematocrya is a rare blood disorder characterized by a decrease in the ability of red blood cells to change shape and flow through tiny blood vessels.
Hematocryal
Hematocryal is an adjective that refers to the quality of being related to or characteristic of the blood. It can also be used to describe something that is hematocrit, which is a medical term that refers to the proportion of red blood cells in the blood.
Hematocrystallin
Hematocrystallin is a type of crystallin protein that is found in the lens of the eye. It is a major component of the crystallin protein family, which is responsible for maintaining the transparency and refractive properties of the lens. Hematocrystallin is particularly abundant in the lens cortex and is thought to play a role in the prevention of lens opacity and cataract formation.
Hematocyst
Hematocyst is a rare type of cyst that forms in the bone marrow or other soft tissues of the body. It is a non-cancerous, fluid-filled sac that contains blood cells. Hematocysts are usually benign and can be treated with surgery or other minimally invasive procedures.
Hematocyte
Hematocyte refers to a cell in the blood that contains hemoglobin or produces hemoglobin, especially a red blood cell that distributes oxygen to tissues and organs throughout the body.
Hematocytes
Hematocytes are cells that are responsible for the formation of blood and the production of platelets, white blood cells, and red blood cells.
Hematocytometer
A hematocytometer is a laboratory instrument used to count the number of red blood cells and other blood cells in a sample of blood. It is a specialized microscope chamber that allows the blood sample to be spread out in a uniform layer, allowing the number of cells to be accurately counted.
Hematocytopenia
Hematocytopenia is a medical condition characterized by a decrease in the number of red blood cells, white blood cells, or platelets in the blood. It is often a symptom of various underlying disorders, such as chronic kidney disease, liver disease, or certain types of cancer. Hematocytopenia can also occur as a side effect of certain medications or treatments.
Hematoencephalic
Hematoencephalic refers to a medical condition where there is a communication between the blood vessels of the brain and the cerebrospinal fluid. This occurs due to a tear or a hole in the membranous structure called the dura mater, which surrounds the brain and spinal cord, allowing blood to leak into the cerebrospinal fluid.
Hematogenesis
Hematogenesis is the process by which blood cells are produced in the bone marrow through the differentiation of blood stem cells.
Hematogenous

It involves the examination of the blood and its components, such as red and white blood cells, platelets, and plasma, to identify abnormalities that may indicate various medical conditions, including anemia, bleeding disorders, and blood cancers like leukemia.
Hematolysis
Hematolysis refers to the breakdown or destruction of red blood cells in the body, often resulting in the release of hemoglobin and bilirubin into the bloodstream. This process can be a normal part of the degradation and recycling of old or damaged red blood cells, or it can be caused by certain medical conditions or diseases, such as hemolytic anemia.
Hematoma
A hematoma is a collection of blood that has leaked out of blood vessels and accumulated outside of them. It can occur in response to injury, surgery, or bleeding disorder. Hematomas can appear as a lump or swelling under the skin, and may be painful, swollen, or tender to the touch.
