Humourism
Humorism, the humoral theory, or humoralism, was a system of medicine detailing a supposed makeup and workings of the human body, adopted by Ancient Greek medicine, Ancient Greek and Medicine in ancient Rome, Roman physicians and Greek philosophy, philosophers. Humorism began to fall out of favor in the 17th century and it was definitively disproved with the discovery of microbes. Origin The concept of "humors" may have origins in Ancient Egyptian medicine, or Mesopotamia, though it was not systemized until ancient Greek thinkers. The word ''humor'' is a translation of Greek , (literally 'juice' or 'sap', metaphorically 'flavor'). Early texts on Indian Ayurveda medicine presented a theory of three or four humors (doṣas), which they sometimes linked with the five elements (): earth, water, fire, air, and space. The concept of "humors" (chemical systems regulating human behaviour) became more prominent from the writing of medical theorist Alcmaeon of Croton (c. 540–500 BC). ...

Four Temperaments
The four temperament theory is a proto-psychological theory which suggests that there are four fundamental personality types: sanguine, choleric, melancholic, and phlegmatic. Most formulations include the possibility of mixtures among the types where an individual's personality types overlap and they share two or more temperaments. Greek physician Hippocrates (c. 460 – c. 370 BC) described the four temperaments as part of the ancient medical concept of humourism, that four bodily fluids affect human personality traits and behaviours. Modern medical science does not define a fixed relationship between internal secretions and personality, although some psychological personality type systems use categories similar to the Greek temperaments. The four temperament theory was abandoned after the 1850s. History Temperament theory has its roots in the ancient theory of humourism. It may have originated in Mesopotamia, but it was Greek physician Hippocrates (460–370 BC) (and late ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spleen
The spleen (, from Ancient Greek '' σπλήν'', splḗn) is an organ (biology), organ found in almost all vertebrates. Similar in structure to a large lymph node, it acts primarily as a blood filter. The spleen plays important roles in regard to red blood cells (erythrocytes) and the immune system. It removes old red blood cells and holds a reserve of blood, which can be valuable in case of Shock (circulatory), hemorrhagic shock, and also Human iron metabolism, recycles iron. As a part of the mononuclear phagocyte system, it metabolizes hemoglobin removed from senescent red blood cells. The globin portion of hemoglobin is degraded to its constitutive amino acids, and the heme portion is metabolized to bilirubin, which is removed in the liver. The spleen houses antibody-producing lymphocytes in its white pulp and monocytes which remove antibody-coated bacteria and antibody-coated blood cells by way of blood and lymph node circulation. These monocytes, upon moving to injured ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bile
Bile (from Latin ''bilis''), also known as gall, is a yellow-green/misty green fluid produced by the liver of most vertebrates that aids the digestion of lipids in the small intestine. In humans, bile is primarily composed of water, is produced continuously by the liver, and is stored and concentrated in the gallbladder. After a human eats, this stored bile is discharged into the first section of the small intestine, known as the duodenum. Composition In the human liver, bile is composed of 97–98% water, 0.7% bile salts, 0.2% bilirubin, 0.51% fats ( cholesterol, fatty acids, and lecithin), and 200 meq/L inorganic salts. The two main pigments of bile are bilirubin, which is orange-yellow, and its oxidised form biliverdin, which is green. When mixed, they are responsible for the brown color of feces. About of bile is produced per day in adult human beings. Function Bile or gall acts to some extent as a surfactant, helping to emulsify the lipids in food. B ...

Phlegm
Phlegm (; , ''phlégma'', "inflammation", "humour caused by heat") is mucus produced by the respiratory system, excluding that produced by the throat nasal passages. It often refers to respiratory mucus expelled by coughing, otherwise known as sputum. Phlegm, and mucus as a whole, is in essence a water-based gel consisting of glycoproteins, immunoglobulins, lipids and other substances. Its composition varies depending on climate, genetics, and state of the immune system. Its color can vary from transparent to pale or dark yellow and green, from light to dark brown, and even to dark grey depending on the contents. The body naturally produces about 1 quart (about 1 litre) of phlegm every day to capture and clear substances in the air and bacteria from the nose and throat. Distinction between mucus and phlegm Contrary to popular misconception and misuse, mucus and phlegm are not always the same. Mucus Mucus is a normal protective layering around the airway, eye, nasal turbinate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gallbladder
In vertebrates, the gallbladder, also known as the cholecyst, is a small hollow Organ (anatomy), organ where bile is stored and concentrated before it is released into the small intestine. In humans, the pear-shaped gallbladder lies beneath the liver, although the structure and position of the gallbladder can vary significantly among animal species. It receives bile, produced by the liver, via the common hepatic duct, and stores it. The bile is then released via the common bile duct into the duodenum, where the bile helps in the digestion of fats. The gallbladder can be affected by gallstones, formed by material that cannot be dissolved – usually cholesterol or bilirubin, a product of hemoglobin breakdown. These may cause significant pain, particularly in the upper-right corner of the abdomen, and are often treated with removal of the gallbladder (called a cholecystectomy). Cholecystitis, inflammation of the gallbladder, has a wide range of causes, including result from the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Comedy Of Humours
The comedy of humours is a genre of dramatic comedy that focuses on a character or range of characters, each of whom exhibits overriding traits or ' humours' that dominate their personality, desires and conduct. This comic technique may be found in Aristophanes, but the English playwrights Ben Jonson and George Chapman popularised the genre in the closing years of the sixteenth century. In the later half of the seventeenth century, it was combined with the comedy of manners in Restoration comedy. In Jonson’s ''Every Man in His Humour'' (acted 1598), which made this type of play popular, all the words and acts of Kitely are controlled by an overpowering suspicion that his wife is unfaithful; George Downright, a country squire, must be "frank" above all things; the country gull in town determines his every decision by his desire to "catch on" to the manners of the city gallant. In his Induction to ''Every Man out of His Humour'' (1599). Jonson explains this character formula: ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Erythrocyte Sedimentation Rate
The erythrocyte sedimentation rate (ESR or sed rate) is the rate at which red blood cells in anticoagulated whole blood descend in a standardized tube over a period of one hour. It is a common hematology test, and is a non-specific measure of inflammation. To perform the test, anticoagulated blood is traditionally placed in an upright tube, known as a Westergren tube, and the distance which the red blood cells fall is measured and reported in millimetres at the end of one hour. Since the introduction of automated analyzers into the clinical laboratory, the ESR test has been automatically performed. The ESR is influenced by the aggregation of red blood cells: blood plasma proteins, mainly fibrinogen, promote the formation of red cell clusters called '' rouleaux'' or larger structures (interconnected rouleaux, irregular clusters). As according to Stokes' law the sedimentation velocity varies like the square of the object's diameter, larger aggregates settle faster. While aggrega ...
