The Dhatus or the body tissues in Ayurveda have been described to be of seven types viz. Rasa, Rakta, Mamsa, Meda, Asthi, Majja, Shukra.

1. Rasa: It is the first basic body tissue. It can be compared crudely with serum although it may not always mean so. It primarily performs the function of nourishment, giving body energy and glow, soft and smoothness.

2. Rakta: It is an important body element also known as blood. It gives life to each and every tissue of body.

3. Mamsa: This comprises of the soft and bulky fleshy parts of body. It can be called as muscle tissue and gives strength, gives body a definite shape and structure.

4. Meda: These are soft parts, which are also known as fats or Adipose tissue. It protects the inner structures and acts as reservoir of energy and lubricates the most vital parts such as brain and joints etc.

5. Asthi: The bony tissue that is very hard and solid is what Asthi Dhatu means. It performs the function of protecting vital organs, giving body a definite structure.

6. Majja: Soft, fleshy part situated inside bones also known as Bone marrow is what is termed as Majja Dhatu in Ayurveda. It serves the function of making an individual intelligent and nourishes the bones.

7. Shukra: This refers to a tissue that plays a major role in the reproduction. Although many people try to compare it with Seminal fluid, it is not limited to semen alone. The references suggest that it is some thing, which is circulating through out the body and is responsible for giving bravery like qualities to the individual. May be reproduction of the new cells that is going on every moment forms a part of the functions assigned to Shukra Dhatu. There is no doubt that it is the most important function of Shukra to reproduce by offering the best quality sperms and ovum from both males as well as females.

Malas: In every metabolic process there two parts as a result of the process. One is a good and a useful part and the other is waste product. Waste parts or bad products ought to be removed out of body in order to contain their toxic effects on the body. There are two types of Malas viz. Liquid Malas and the Solid Malas. Liquid type of Malas are urine, sweat etc. and solid are stool, hairs, etc.

1. Mootra (Urine): In Ayurved, urine production is described in a different way. The process of urine production starts form large intestine where the water is re-absorbed from the GI Tract. Then it traverses through kidneys, ureters, urinary bladder and urethra.

2. Pureesha(Stool) : These are solid forms of excreta which holds the body balance. It is said to be very important that these Malas normally in the body offer several useful functions.

Dosha, Dhatu and Malas are the three pillars of body. If any one of these pillars is weak then the healthy state of body falls in a danger. Hence health can also be defined as the perfect equilibrium between Doshas, Dhatus and Malas.
