Ayurveda studies the human body as a whole functional unit, rather than individual ones. The human body is complex in nature which compromises of organs and tissues that function in perfect harmony with each other to ensure health. Dhatus which are the several tissues in the body are responsible for functioning and maintaining organ functions and the structure of the body. Ayurveda recognizes the following seven dhatus:

Rasa - Sap/FluidChyle.

Rakta - Blood.

Mamsa - Muscle.

Asthi - Bone

Majja - Bone Marrow

Meda – Fat, Brain and Spinal Cord

Sukra - Sperm and Ovum

These seven tissues are vital to the growth and development of the body. Each dhatu individually as well as collectively play the part in constructing the body.In Sanskrit the word dhatu means ‘to bind together’, and this is exactly what the dhatus do, they bind different parts and functions of the body to form a cohesive whole.

After the food has been consumed and digested, the digestive system releases nourishment in form of life sap or fluid, known as ‘Rasa’. Rasa is the primary source on which all other dhatus are built. As Rasa enters the blood stream, it is transformed into blood or ‘Rakta’. Rakta is the source of existence. Rakta nourishes every cell and tissue in the body. It is made up of white blood cells, red blood cells, plasma and platelets. Rakta is also responsible for blood purification due to the gaseous exchange of oxygen and carbon dioxide by the lungs.

Rakta dhatu helps to develop, build and maintain muscles, known as ‘Mamsa’. Mamsa dhatu is attached to the skeleton, and facilitate joint movements and provides strength to the body. The fat or ‘Meda’ dhatu is derived from Mamsa. Medha functions as a body heat regulator and is responsible for lubrication of the muscles. Meda dhatu is distributed all over the body in uneven quantities, defining the shape of the body. It also protects the body from the impact of external injury. The bones or ‘Asthi’ dhatu is developed from Meda. It is the skeleton which is made of bone tissues and cartilage. The Asthi dhatu supports all other dhatus as it works as the basic structure that holds all the organs. It also defines the shape and size of the body. The Asthi dhatu is responsible for the formation of ‘Majja’, also known as bone marrow.
