Biology Prefixes and Suffixes: (hem- or hemo- or hemato-)


The prefix (hem- or hemo- or hemato-) refers to blood. It is derived from the Greek (haimo-) and Latin (haemo-) for blood.

Hematic (hemat-ic) - of or relating to blood.

Hematocyte (hemato-cyte) - a blood cell.

Hematocrit (hemato-crit) - process of separating blood cells from plasma in order to obtain the ratio of the volume of red blood cells per given volume of blood.

Hematoid (hemat-oid) - resembling blood.

Hematology (hemato-logy) - field of medicine concerned with the study of diseases of the blood and bone marrow.

Hematoma (hemat-oma) - abnormal accumulation of blood in an organ or tissue as a result of a broken blood vessel. A hematoma can also be a cancer that occurs in the blood.

Hematopoiesis (hemato-poiesis) - the process of forming and generating blood components and blood cells of all types.

Hematuria (hemat-uria) - the presence of blood in urine resulting from a leakage in the kidneys or other part of the urinary tract.

Hemoglobin (hemo-globin) - iron containing protein found in red blood cells.

Hemolymph (hemo-lymph) - fluid similar to blood that circulates in arthropods such as spiders and insects.

Hemolysis (hemo-lysis) - destruction of red blood cells as a result of cell rupture.

Hemophilia (hemo-philia) - sex-linked blood disorder characterized by excessive bleeding due to a defect in a blood clotting factor.

A person with hemophilia has a tendency toward bleed uncontrollably.

Hemoptysis (hemo-ptysis) - the spewing or coughing up of blood from the lungs or airway.

Hemorrhage (hemo-rrhage) - abnormal and excessive flow of blood.

Hemorrhoids (hemo-rrhoids) - swollen blood vessels located in the anal canal.

Hemostasis (hemo-stasis) - the first stage of wound healing in which the stoppage of blood flow from damaged blood vessels occurs.

Hemothorax (hemo-thorax) - an accumulation of blood in the pleural cavity (space between the chest wall and lungs).

Hemotoxin (hemo-toxin) - a toxin that destroys red blood cells by inducing hemolysis.
