  2. Hemoglobin - Wikipedia

    en.wikipedia.org/wiki/Hemoglobin

    In mammals, hemoglobin makes up about 96% of a red blood cell's dry weight (excluding water), and around 35% of the total weight (including water). [5] Hemoglobin has an oxygen-binding capacity of 1.34 mL of O 2 per gram, [6] which increases the total blood oxygen capacity seventy-fold compared to dissolved oxygen in blood plasma alone. [7]

  3. Hemolymph - Wikipedia

    en.wikipedia.org/wiki/Hemolymph

    Hemolymph fills all of the interior (the hemocoel) of the animal's body and surrounds all cells. It contains hemocyanin, a copper-based protein that turns blue when oxygenated, instead of the iron-based hemoglobin in red blood cells found in vertebrates, giving hemolymph a blue-green color rather than the red color of vertebrate blood. When not ...

  4. Oxygen–hemoglobin dissociation curve - Wikipedia

    en.wikipedia.org/wiki/Oxygen–hemoglobin...

    Myo-inositol trispyrophosphate (ITPP), also known as OXY111A, is an inositol phosphate that causes a rightward shift in the oxygen hemoglobin dissociation curve through allosteric modulation of hemoglobin within red blood cells. It is an experimental drug intended to reduce tissue hypoxia. The effects appear to last roughly as long as the ...

  5. Iron in biology - Wikipedia

    en.wikipedia.org/wiki/Iron_in_biology

    Of this, about 2.5 g is contained in the hemoglobin needed to carry oxygen through the blood (around 0.5 mg of iron per mL of blood), [25] and most of the rest (approximately 2 grams in adult men, and somewhat less in women of childbearing age) is contained in ferritin complexes that are present in all cells, but most common in bone marrow ...

  6. Blood - Wikipedia

    en.wikipedia.org/wiki/Blood

    4.7 to 6.1 million (male), 4.2 to 5.4 million (female) erythrocytes: [13] Red blood cells contain the blood's hemoglobin and distribute oxygen. Mature red blood cells lack a nucleus and organelles in mammals. The red blood cells (together with endothelial vessel cells and other cells) are also marked by glycoproteins that define the different ...

  7. 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 ...

  8. Bohr effect - Wikipedia

    en.wikipedia.org/wiki/Bohr_effect

    The Bohr effect increases the efficiency of oxygen transportation through the blood. After hemoglobin binds to oxygen in the lungs due to the high oxygen concentrations, the Bohr effect facilitates its release in the tissues, particularly those tissues in most need of oxygen. When a tissue's metabolic rate increases, so does its carbon dioxide ...

  9. Extracellular fluid - Wikipedia

    en.wikipedia.org/wiki/Extracellular_fluid

    One of the main roles of extracellular fluid is to facilitate the exchange of molecular oxygen from blood to tissue cells and for carbon dioxide, CO 2, produced in cell mitochondria, back to the blood. Since carbon dioxide is about 20 times more soluble in water than oxygen, it can relatively easily diffuse in the aqueous fluid between cells ...
