The universe and the human body are made up of five basic elements collectively known as Panch Mahabhootas. These five elements are Aakash (Ether/Sky), Vayu (Air), Agni (Fire), Aapa (Water) & Prithvi (Earth). The sixth mandatory component of life is Atma (Life spirit) without which life winds up. The human body is made up of Doshas (Bio humor), Dhatus (Body matrix), and malas (excretable product).
Vata, Pitta, and Kapha called Tridoshas are physiological entities of the body that are responsible to carry out all the functions of the body. Dhatus are the structural entities of the body. Rasa (Plasma), Rakta (Blood cells), Mamsa (Muscular tissue), Meda (fatty tissue), Majja (Bone marrow), Asthi (Bone tissue) and Shukra (Hormonal & other secretions) are the Dhatus. The unwanted or waste products of the body which are excretable produced in the body as by-products of metabolism. These products are known as malas which include sweda (sweat), pureesh (faeces), & mutra (urine). All the biotransformation within the body occurs through body channels (Srotases) which are the sites for the action of Agni.
