After a fatty meal, plasma transiently appears turbid. White blood cells (WBC) fight infection and are part of your immune system. Talk to a Heart Nurse.

Giant tube worms have unusual hemoglobins that allow them to live in extraordinary environments. Hemocyanin, a copper-containing protein chemically unlike hemoglobin, is found in some crustaceans. The osmotic effect of serum albumin retains fluid within the circulation, opposing the hydrostatic forces that tend to drive the fluid outward into the tissues. Another example of a hydraulic function is the jumping spider, in which blood forced into the legs under pressure causes them to straighten for a powerful jump, without the need for bulky muscular legs.[35]. Unicellular organisms, primitive multicellular animals, and the early embryos of higher forms of life lack a circulatory system. In Judaism, animal blood may not be consumed even in the smallest quantity (Leviticus 3:17 and elsewhere); this is reflected in Jewish dietary laws (Kashrut). An average young male has a plasma volume of about 35 millilitres and a red cell volume of about 30 millilitres per kilogram of body weight.

Many substances are recycled through the blood; for example, iron released during the destruction of old red cells is conveyed by the plasma to sites of new red cell production where it is reused. It is green in color in dilute solutions. It also transports metabolic waste products away from those same cells. There is little variation in the blood volume of a healthy person over long periods, although each component of the blood is in a continuous state of flux. [8] Insects and some mollusks use a fluid called hemolymph instead of blood, the difference being that hemolymph is not contained in a closed circulatory system. The total amount of blood in humans varies with age, sex, weight, body type, and other factors, but a rough average figure for adults is about 60 millilitres per kilogram of body weight. Plasma is yellowish in color and is made up mostly of water, but it also contains proteins, sugars, hormones and salts. Above the clot is a layer of red blood cells (the "blood"). (2019). The decreased binding to carbon dioxide in the blood due to increased oxygen levels is known as the Haldane effect, and is important in the transport of carbon dioxide from the tissues to the lungs.

It also transports metabolic waste products away from those same cells. Blood is one of the body fluids that has been used in art. In most insects, this "blood" does not contain oxygen-carrying molecules such as hemoglobin because their bodies are small enough for their tracheal system to suffice for supplying oxygen. As Lawlor states:.mw-parser-output .templatequote{overflow:hidden;margin:1em 0;padding:0 40px}.mw-parser-output .templatequote .templatequotecite{line-height:1.5em;text-align:left;padding-left:1.6em;margin-top:0}, In many Aboriginal rituals and ceremonies, red ochre is rubbed all over the naked bodies of the dancers.
