  2. Hemolysin - Wikipedia

    en.wikipedia.org/wiki/Hemolysin

    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.

  3. Hemoglobin - Wikipedia

    en.wikipedia.org/wiki/Hemoglobin

    Hemoglobin in normal red blood cells is protected by a reduction system to keep this from happening. Nitric oxide is capable of converting a small fraction of hemoglobin to methemoglobin in red blood cells. The latter reaction is a remnant activity of the more ancient nitric oxide dioxygenase function of globins.

  4. Red blood cell - Wikipedia

    en.wikipedia.org/wiki/Red_blood_cell

    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 ...

  5. Hemolysis - Wikipedia

    en.wikipedia.org/wiki/Hemolysis

    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).

  6. Hemoprotein - Wikipedia

    en.wikipedia.org/wiki/Hemoprotein

    Hemoglobin and myoglobin are examples of hemeproteins that respectively transport and store of oxygen in mammals and in some fish. [9] Hemoglobin is a quaternary protein that occurs in the red blood cell, whereas, myoglobin is a tertiary protein found in the muscle cells of mammals.

  7. Blood cell - Wikipedia

    en.wikipedia.org/wiki/Blood_cell

    Red blood cells are much smaller than most other human cells. RBCs are formed in the red bone marrow from hematopoietic stem cells in a process known as erythropoiesis. In adults, about 2.4 million RBCs are produced each second. The normal RBCs count is 4.5 to 5 millions per cu.mm. RBCs have a lifespan of approximately 100-120 days.

  8. Hemolytic anemia - Wikipedia

    en.wikipedia.org/wiki/Hemolytic_anemia

    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 ]

  9. Erythropoiesis - Wikipedia

    en.wikipedia.org/wiki/Erythropoiesis

    A feedback loop involving erythropoietin helps regulate the process of erythropoiesis so that, in non-disease states, the production of red blood cells is equal to the destruction of red blood cells and the red blood cell number is sufficient to sustain adequate tissue oxygen levels but not so high as to cause sludging, thrombosis, or stroke ...
