Haemoperfusion
Haemoperfusion refers to a medical treatment where the blood is pumped through a cartridge or column that contains adsorbents or enzymes to remove toxins or waste products from the blood. It is often used to treat poisoning, overdose, or fulfilment of a toxin, such as in cases of intentional poisoning. The goal of haemoperfusion is to remove the toxin from the blood before it causes serious damage to the body.
Haemoperitoneum
Haemoperitoneum refers to a medical condition where there is bleeding into the peritoneal cavity, usually as a result of an injury, surgery, or trauma. The peritoneal cavity is the space between the abdominal wall and the abdominal organs, and in a normal situation, it is filled with a small amount of fluid. Haemoperitoneum occurs when there is an accumulation of blood within this cavity, which can put pressure on the surrounding organs and potentially cause life-threatening complications if left untreated.
Haemophagic
Haemophagic refers to the process of drinking blood, especially in a non- nutritional context. It can also describe the habit of consuming blood in a medical or scientific sense.
Haemophilia
Haemophilia is a group of genetic disorders that affect the blood's ability to clot, leading to prolonged bleeding after an injury. The most common forms of haemophilia are haemophilia A and haemophilia B. People with haemophilia may experience frequent and spontaneous bleeding into their joints, muscles, or internal organs, which can cause pain, swelling, and limited mobility. Treatment for haemophilia typically involves replacement therapy with clotting factor concentrates, which help the blood to clot normally.
Haemophiliac
A person who has a genetic disorder characterized by a deficiency of blood clotting factors, which can lead to easy bruising, prolonged bleeding after an injury, and bleeding into joints and muscles.
Haemophiliacs
Haemophiliacs refer to individuals suffering from haemophilia, a rare genetic disorder characterized by the inability of the blood to clot properly, leading to prolonged bleeding after an injury or spontaneously in joints, muscles, or other soft tissues.
Haemophilic
Haemophilic refers to a condition involving a bleeding disorder, typically Haemophilia, where the blood does not clot properly due to a deficiency or abnormality of clotting factors VIII or IX. This can cause spontaneous bleeding into joints, muscles, and other soft tissues, leading to pain, swelling, and disability.

Haemorrhage
Haemorrhage is a noun that refers to the escape of blood from a vessel, usually as a result of an injury or a medical condition. It can also refer to a sudden and copious flow of blood or other bodily fluid, such as a nosebleed or a haemorrhoid. In a broader sense, haemorrhage can also refer to a significant or catastrophic loss of something, such as capital, money, or a decline in population.
Haemorrhaged
Verb: The verb "haemorrhaged" is the past tense of the verb "haemorrhage", which means to lose or shed blood excessively, often rapidly and uncontrollably. It can also mean to lose or suffer a significant loss or decline, often in a sudden and severe manner. For example: "The company haemorrhaged money after the new product failed to sell well."
Haemorrhages
Haemorrhages refer to the escape of blood from a blood vessel or organ due to damage, trauma, or disease. This can occur internally, such as in the brain, liver, or kidneys, or externally, like those caused by cuts, wounds, or surgical procedures.
Haemorrhagia
Haemorrhage refers to the escape of blood from a blood vessel or a rupture in a blood vessel, typically as a result of injury or malfunction.
Haemorrhagic
Haemorrhagic refers to or relating to bleeding or hemorrhage, often used to describe a condition or symptom characterized by excessive bleeding or hemorrhaging.

They are a type of apicomplexan parasite, which also includes malaria-causing pathogens like Plasmodium. Haemosporidians are typically transmitted through the bite of an infected vector, such as a mosquito or tick, and cause a range of symptoms including anemia, jaundice, and other blood-related disorders. Examples of haemosporidians include Plasmodium, Theileria, and Babesia.
Haemostasia
Haemostasia refers to the process by which the body stops bleeding after an injury. It involves a series of physiological responses, including vasoconstriction, clot formation, and platelet plug formation, which work together to prevent excessive blood loss and promote healing.
Haemostasis
Haemostasis refers to the process of stopping blood flow after an injury, which involves a complex interplay of blood vessels, platelets, and clotting factors. It is the body's natural response to bleeding, aiming to restore blood clotting and prevent excessive blood loss.
Haemostat
A haemostat (also spelled hematostatic) is a medical device or instrument used to stop bleeding by compressing or clamping small blood vessels, usually used in surgical procedures. It is designed to control bleeding, prevent blood loss, and promote hemostasis (the process of stopping bleeding). Haemostats can be used temporarily to control bleeding while a patient is being prepared for surgery, or permanently to ligate (tie off) a blood vessel. They come in various shapes, sizes, and materials, including forceps, clips, and sutures.
Haemostatic
Haemostatic refers to the process of stopping or controlling bleeding. It describes the physiological process by which the body regulates blood loss after an injury, including the formation of a blood clot, platelet aggregation, and the activation of clotting factors.
