question: The role of blood in the color of our flesh and what would it look like if we had no blood.
comment: Flesh appears "reddish" in humans because hemoglobin, a type of protein, contains an iron component which to a greater or lesser degree acts as a pigment for flesh. & #x200B; Decellularized organs/tissues are "white". You might find this example interesting: & #x200B; [ URL_1 ]( URL_0 )
passages: Section::::Color.:Chlorocruorin.
  
  The blood of most annelid worms and some marine polychaetes use chlorocruorin to transport oxygen. It is green in color in dilute solutions.
  
  Section::::Color.:Hemerythrin.
  
  Hemerythrin is used for oxygen transport in the marine invertebrates sipunculids, priapulids, brachiopods, and the annelid worm, magelona. Hemerythrin is violet-pink when oxygenated.

    was a medical doctor who was introduced to Diva by Amshel in 1917 during the Russian Revolution. At this time, he became one of her chevaliers, after which he wears only white clothing as a symbol of his being Diva's chevalier because it was what he was wearing when he met her. At the time, he wanted to free himself from seeing humans kill each other, but afterwards, he started seeing humans as insignificant and beneath him. As time passed, he realized the world of the chiropterans is just as full of war as the human one.
   Section::::Politics and society.:Known races.:Scabmettler.
  
  Stocky, gray-skinned human-like beings whose blood, when shed, congeals immediately into a solid protective layer. Using a special herb which delays coagulation, the Scabmettlers are able to mold the blood into elaborate armor. They practice a unique form of martial, arena combat called "mortu crutt", which emphasises pounding, hammer-like strikes, as edged weapons are nearly useless against them due to their rapid coagulation.

   Flesh Color
  
  Flesh Color (French: Couleur Chair) is a 35 mm film by François Weyergans (Prix Goncourt 2005). Weyergans is one of the forty members known as immortals of the French Academy (L'Académie française). It features a band called Flesh Colour formed in 1976 in Brussels-Capital.

   Section::::Diagnosis.
  
  Section::::Diagnosis.:Classification.
  
  Poikiloderma vasculare atrophicans, or PVA, indicates that extra or altered skin pigmentation ("poikiloderma") is occurring, associated with heightened visibity of capillaries ("vasculare", referring to telangiectasia) under the skin, related to thinning and wasting away ("atrophicans") of the skin and its tissue. Telangiectasia is an enlargement of capillaries underneath the skin.
   There are at least five different pigments that determine the color of the skin. These pigments are present at different levels and places.
  
  BULLET::::- Melanin: It is brown in color and present in the basal layer of the epidermis.
  
  BULLET::::- Melanoid: It resembles melanin but is present diffusely throughout the epidermis.
  
  BULLET::::- Carotene: This pigment is yellow to orange in color. It is present in the stratum corneum and fat cells of dermis and superficial fascia.
  
  BULLET::::- Hemoglobin (also spelled "haemoglobin"): It is found in blood and is not a pigment of the skin but develops a purple color.
   Hemoglobin is the principal determinant of the color of blood in vertebrates. Each molecule has four heme groups, and their interaction with various molecules alters the exact color. In vertebrates and other hemoglobin-using creatures, arterial blood and capillary blood are bright red, as oxygen imparts a strong red color to the heme group. Deoxygenated blood is a darker shade of red; this is present in veins, and can be seen during blood donation and when venous blood samples are taken. This is because the spectrum of light absorbed by hemoglobin differs between the oxygenated and deoxygenated states.
   In this episode Conan finds out he has a long lost brother named Eric Ochoa, the most pale of all. He secretly fights crime in the west coast known as the "pale Kight". 
  
  Jim then starts reminiscing about the "good times" they had together, Most of which involve O'Brien either wetting himself or running scared.
  
  One of the machines starts beeping and a nurse explains that his urine count is off the chart, and suggests that giving Jim a spongebath Would help.
   Section::::Family history.
   Fåhræus (a Swedish physician who devised the erythrocyte sedimentation rate) suggested that the Ancient Greek system of humorism, wherein the body was thought to contain four distinct bodily fluids (associated with different temperaments), were based upon the observation of blood clotting in a transparent container. When blood is drawn in a glass container and left undisturbed for about an hour, four different layers can be seen. A dark clot forms at the bottom (the "black bile"). Above the clot is a layer of red blood cells (the "blood"). Above this is a whitish layer of white blood cells (the "phlegm"). The top layer is clear yellow serum (the "yellow bile").
   "We can conclude for now that the Shroud image is that of a real human form of a scourged, crucified man. It is not the product of an artist. The blood stains are composed of hemoglobin and also give a positive test for serum albumin. The image is an ongoing mystery and until further chemical studies are made, perhaps by this group of scientists, or perhaps by some scientists in the future, the problem remains unsolved."
  
  Section::::Members of the S.Tu.R.P. in 1978.
  
  BULLET::::- Joseph S. Accetta , Lockheed Corporation (Turin researcher in 1978).
   In 1977, a team of scientists selected by the Holy Shroud Guild developed a program of tests that they proposed to conduct on the Shroud. The Archbishop of Turin granted permission. The STURP scientists conducted their testing over five days in 1978. McCrone, upon analyzing the samples he had, concluded that the red stains that had been pointed to as blood were actually pigment—specifically, red ochre and vermilion tempera paint.
    is a Frenchman and the head scientist studying chiropterans for Cinq Flèches. He was in charge of the development of Delta 67, working under Solomon and with his assistant Archer. After Solomon defected from the group, Amshel appoints him to the head of the Cinq Flèches American branch. Despite knowing their true nature and plans, Van sided with the chiropterans and aided them in their efforts to spread chiropterans around the world. Van is often shown to be eating some kind of hard candy, sometimes offering some to colleagues.
   The following list shows the six categories of the Fitzpatrick scale in relation to the 36 categories of the older von Luschan scale:
   Blood vessels also transport red blood cells which contain the oxygen necessary for daily activities. The amount of red blood cells present in your vessels has an effect on your health. Hematocrit tests can be performed to calculate the proportion of red blood cells in your blood. Higher proportions result in conditions such as dehydration or heart disease while lower proportions could lead to anemia and long-term blood loss.
   The color blood red is a dark shade of the color red meant to resemble the color of human blood (which is composed of oxygenated red erythrocytes, white leukocytes, and yellow blood plasma) by cinnabar, a quick silver thermometer analogue display. It is the iron in hemoglobin specifically that gives blood its red color. The actual color ranges from crimson to a dark brown-blood depending on how oxygenated the blood is, and may have a slightly orange hue. Deoxygenated blood, which circulates closer to the body's surface and which is therefore generally more likely to be seen than oxygenated blood, issues from bodily veins in a dark red state, but quickly oxygenates upon exposure to air, turning a brighter shade of red. This happens more quickly with smaller volumes of blood such as a pinprick and less quickly from cuts or punctures that cause greater blood flows such as a puncture in the basilic vein: all blood collected during a phlebotomy procedure is deoxygenated blood, and it does not usually have a chance to become oxygenated upon leaving the body. Arterial blood, which is already oxygenated, is also already a brighter shade of red— this is the blood see from a pulsating neck, arm, or leg wound, and it does not change color upon exposure to air. The color "blood red", therefore, covers both these states: the darker deoxygenated color and the brighter oxygenated one. Also, dried blood often has a darker, rust-colored quality: all dried blood has been oxygenated and then desiccated, causing the cells within it to die. This blood is often darker than either shade of red that can be seen in fresh blood. 
   It was the Spaniards who gave the world the notion that an aristocrat's blood is not red but blue. The Spanish nobility started taking shape around the ninth century in classic military fashion, occupying land as warriors on horseback. They were to continue the process for more than five hundred years, clawing back sections of the peninsula from its Moorish occupiers, and a nobleman demonstrated his pedigree by holding up his sword arm to display the filigree of blue-blooded veins beneath his pale skin—proof that his birth had not been contaminated by the dark-skinned enemy.
  
  Section::::Europe.
   Melanin is brown, non-refractile, and finely granular with individual granules having a diameter of less than 800 nanometers. This differentiates melanin from common blood breakdown pigments, which are larger, chunky, and refractile, and range in color from green to yellow or red-brown. In heavily pigmented lesions, dense aggregates of melanin can obscure histologic detail. A dilute solution of potassium permanganate is an effective melanin bleach.
  
  Section::::Genetic disorders and disease states.
   In the same population it has been observed that adult human females are considerably lighter in skin pigmentation than males. Females need more calcium during pregnancy and lactation, and vitamin D which is synthesized from sunlight helps in absorbing calcium. For this reason it is thought that females may have evolved to have lighter skin in order to help their bodies absorb more calcium.
  
  The Fitzpatrick scale is a numerical classification schema for human skin color developed in 1975 as a way to classify the typical response of different types of skin to ultraviolet (UV) light:
  
  Section::::Development.:Aging.
   BULLET::::- Oxyhemoglobin: It is also found in blood and is not a pigment of the skin. It develops a red color.
  
  There is a correlation between the geographic distribution of UV radiation (UVR) and the distribution of indigenous skin pigmentation around the world. Areas that highlight higher amounts of UVR reflect darker-skinned populations, generally located nearer towards the equator. Areas that are far from the tropics and closer to the poles have lower concentration of UVR, which is reflected in lighter-skinned populations.

  Section::::Reception.
   The number of white blood cells can give an indication of infection. The specific subtypes can also give clues as to the type on infection. The amount of red blood cells are an obvious sign of bleeding.
  
  Section::::Interpretation of pleural fluid analysis.:Cultures and stains.
  
  If the effusion is caused by infection, microbiological culture may yield the infectious organism responsible for the infection, sometimes before other cultures (e.g. blood cultures and sputum cultures) become positive. A Gram stain may give a rough indication of the causative organism. A Ziehl-Neelsen stain may identify tuberculosis or other mycobacterial diseases.
