The term vermicomposting means the use of earthworms for composting organic residues. Earthworms can consume practically all kinds of organic matter and they can eat their own body weight per day. The excreta (castings) of the worms are rich in nitrate, available forms of P, K, Ca and Mg. The passage of soil through earthworms promotes the growth of bacteria and actinomycetes. Actinomycetes thrive in the presence of worms and their content in worm casts is more than six times that in the original soil.

Oxygen Concentration Arteries carry oxygenated blood (with the exception of the pulmonary artery and umbilical artery). Veins carry deoxygenated blood (with the exception of pulmonary veins and umbilical vein).
Types Pulmonary and systemic arteries. Superficial veins, deep veins, pulmonary veins and systemic veins
Direction of Blood Flow From the heart to various parts of the body. From various parts of the body to the heart.
Anatomy Thick, elastic muscle layer that can handle high pressure of the blood flowing through the arteries. Thin, elastic muscle layer with semilunar valves that prevent the blood from flowing in the opposite direction.
Overview Arteries are red blood vessels that carry blood away from the heart. resistance vessels Veins are blue blood vessels that carry blood towards the heart. capacitance vessels
