Earthworm - Morphology, Diagram and Anatomy of Earthworm Circulatory System. Earthworms have a closed circulatory system, constituting a heart, blood vessels, and capillaries. The segments 4-6 consist of blood glands that help in the production of blood cells and haemoglobin. Respiratory System. Earthworms lack a well-developed structure for respiration. They respire through their moist skin by diffusion. Circulatory System of Earthworm - Biology Discussion Hence, earthworms can live in well aerated water and are not drowned. They can also live for several hours without O 2, in this condition they probably carry on anaerobic respiration. Blood Glands: In the segments 4th, 5th and 6th above the pharyngeal mass are several groups of small rounded follicles of red colour, which are called blood glands. Earthworm Anatomy and Dissection Guide - Biology Junction The pumping organs of the circulatory system are five aortic arches. Circulatory fluids travel from the arches through the ventral blood vessel to capillary beds in the body. The fluids then collect in the dorsal blood vessel and reenter the aortic arches. The earthworm takes in a mixture of soil and organic matter through its mouth, which is the beginning of the digestive tract.
