*The rakta dhatu is formed from its predecessor [[rasa dhatu]]. The nourishing portion of [[rasa dhatu]] and constituents of nutrient fluid (ahara rasa) are transformed into rakta dhatu by action of ranjakapitta (type of pitta responsible for colour pigments). [Cha. Sa. [[Chikitsa Sthana]] 15/28] This process takes place in liver and spleen.[Su.Sa.Sutra Sthana 14/4-5] | *The rakta dhatu is formed from its predecessor [[rasa dhatu]].

The liver acts as the major blood reservoir. It stores about 450 milliliters or almost 10 percent of the body's total blood volume. This capacity can increase up to 1 litre in certain cases due to the expanding capacity of the liver. It synthesizes some proteins including coagulation factors I (fibrinogen), II (prothrombin), V, VII, VIII, IX, X, XI, XII, XIII, as well as protein C, protein S and antithrombin. All of these play important roles in blood physiology. Moreover, the liver is a major site of production for thrombopoietin, a glycoprotein hormone that regulates the production of platelets by the bone marrow. The liver plays a major role in glucose, protein, and lipids present in the blood. It also purifies and protects blood from harmful toxins, metabolites, and heavy metals. | The liver acts as the major blood reservoir.

Thus, bone marrow is the site of formation of blood cells; whereas the liver is the major site in maturation of blood cells and maintaining the physiological status of blood tissue. | Thus, bone marrow is the site of formation of blood cells; whereas the liver is the major site in maturation of blood cells and maintaining the physiological status of blood tissue. | ||
