Haemoglobin Sentence Examples
The blood is coloured red by haemoglobin in blood corpuscles.
Blood coloured red with haemoglobin.

It enters into combination with haemoglobin, forming a bright scarlet compound and interfering with respiration.
Haemoglobin is composed of a basic albumin and an acid substance haematin; it combines readily with oxygen, carbon dioxide and carbon monoxide to form loose compounds (see Nutrition).
These corpuscles may break down in the blood vessels, and their colouring material (haemoglobin) is set free in the serum.

In Ceratisolen legumen, various species of Arca and a few other species the blood is crimson, owing to the presence of corpuscles impregnated with haemoglobin.Advertisement
By a dilute acid haemoglobin is decomposed into globin, and " haematin," a ferri-pyrrol derivative of the probable formula C34H34N4FeOs; under certain conditions the iron-free " haematoporphyrin " is obtained.
The ' haemoglobin may be transformed into haematoidin, a pigment that does not contain iron, or into a pigment which does contain iron, haemosiderin.
Haemosiderin in the normal process of haemolysis is stored up in the cells of certain organs until required by the organism for the formation of fresh haemoglobin.
In the Gastropoda the muscular tissue of the buccal mass is coloured red by haemoglobin.
Haematogen, introduced by Hommel, claims to contain the albuminous constituents of the blood serum and all the blood salts as well as pure haemoglobin.Advertisement
Iron being a constituent part of the blood itself, there is a direct indication for the physician to prescribe it when the amount of haemoglobin in the blood is lowered or the red corpuscles are diminished.
The first is based on the fact that the iron in the haemoglobin of the blood must be derived from the food, therefore iron medicinally administered is absorbed.
In certain forms of anaemia it increases the number of the red corpuscles and also their haemoglobin content.
When taken by the mouth, however, no such actions are seen, owing to the fact that very minute quantities are absorbed and that these become stored in the liver, where they are converted into organic compounds and ultimately go to form haemoglobin.
They occupy and destroy the red corpuscles, converting the haemoglobin into melanin; they multiply in the blood by sporulation, and produce accessions of fever by the liberation of a toxin at the time of sporulation (Ross).Advertisement
The pathological changes in malaria are due to the deposition of melanin and the detritus of red corpuscles and haemoglobin, and to the congregation of parasites in certain sites (Ross).
In one genus (Planorbis) the plasma of the blood is coloured red by haemoglobin, this being the only instance of the presence of this body in the blood of Glossophorous Mollusca, though it occurs in corpuscles in the blood of the bivalves Arca and Solen (Lankester).
It is colourless and contains definite corpuscles, which are round or elliptical, and in many Metanemertines are coloured red by haemoglobin, being colourless in other species.
In a few forms the blood contains haemoglobin, either in solution or in haematids (red blood-corpuscles).
Whilst it is not a haematinic, in that it does not increase the number of the red blood corpuscles, it very markedly influences the stability of the compounds of the haemoglobin with oxygen.Advertisement
It contains a colourless fluid, with flat, oval, nucleated corpuscles, as a rule colourless, but in some cases tinged with yellow or red haemoglobin.
Haemoglobin is composed of a basic albumin and an acid substance haematin; it combines readily with oxygen, carbon dioxide and carbon monoxide to form loose compounds.
Haematinics are drugs which increase the amount of haemoglobin in the blood.
The haemoglobin would, by its pre-eminent properties of fixing oxygen, serve to furnish the nerve system, which more than any other requires a constant supply, with the necessary oxygen.
An important nucleo-proteid is haemoglobulin or haemoglobin, the colouring matter of the red blood corpuscles of vertebrates; a related substance, haemocyanin, in which the iron of haemoglobin is replaced by copper, occurs in the blood of cephalopods and crayfish.
It is very poisonous, uniting with the haemoglobin of the blood to form carbonyl-haemoglobin.
Haematogenous pigments are derived from the haemoglobin of the red blood corpuscles.
