A red blood cell in a hypotonic solution, causing water to move into the cell A red blood cell in a hypertonic solution, causing water to move out of the cell. Hemolysis or haemolysis (/ h iː ˈ m ɒ l ɪ s ɪ s /), [1] also known by several other names, is the rupturing of red blood cells (erythrocytes) and the release of their contents into surrounding fluid (e.g. blood plasma).
Hemolysins or haemolysins are lipids and proteins that cause lysis of red blood cells by disrupting the cell membrane.Although the lytic activity of some microbe-derived hemolysins on red blood cells may be of great importance for nutrient acquisition, many hemolysins produced by pathogens do not cause significant destruction of red blood cells during infection.
Hemolysis is the breakdown of red blood cells. The ability of bacterial colonies to induce hemolysis when grown on blood agar is used to classify certain microorganisms. This is particularly useful in classifying streptococcal species. A substance that causes hemolysis is called a hemolysin.
A defect of the enzyme results in the premature breakdown of red blood cells. This destruction of red blood cells is called hemolysis. [6] Red blood cell breakdown may be triggered by infections, certain medication, stress, or foods such as fava beans. [1] [3] Depending on the specific mutation the severity of the condition may vary. [2]
In a healthy person, a red blood cell survives 90 to 120 days in the circulation, so about 1% of human red blood cells break down each day. [ 38 ] [ unreliable medical source? ] The spleen (part of the reticulo-endothelial system ) is the main organ that removes old and damaged RBCs from the circulation. [ 2 ]

Red blood cells (RBCs), referred to as erythrocytes (from Ancient Greek erythros 'red' and kytos 'hollow vessel', with -cyte translated as 'cell' in modern usage) in academia and medical publishing, also known as red cells, [1] erythroid cells, and rarely haematids, are the most common type of blood cell and the vertebrate's principal means of delivering oxygen (O 2) to the body tissues—via ...
