Review of physiological function of pittadhara kala w.s.r. to erythorpoiesis

Kala Sharir is an important part of Ayurved anatomy but not explained clearly in text. Kala is supposed to be situated between Dhatu and concerning Ashaya. It is formed with layers or membranes of our body and correlated with mucous, serous, fibrous membrane. There are many layers or membranes in the body which form an envelope over the organs. They provide support and protections to the organs. Kala are seven in number and Pittadhara Kala is sixth one present in between Amashya and Pakwashaya that is Grahani correlated as small intestine. Pittadhara Kala is correlated with the lining membranes of small intestine which plays vital role in digestion and absorption of all nutritive substances like Vit B12, Folic acid and iron which are the main factors for the process of formation and maturation of R.B.C. Acharya Dalhan had stated Pittadhara Kala as Majjadhara Kala. Majja Dhatu is present in the cavity of long bones which is correlated with bone marrow where R.B.C production takes place by Erythropoisis. Erythropoiesis is the process of the origin, development and maturation of erythrocytes. Impaired Pittadhara Kala causes malabsorption of Vit B12 and iron and leads to anemia.
