What is the circulatory system of the ladybug?

Answer 1

fist of all it is known as an 'open' circulatory system.. that means the circulatory fluid (hemolymph) is not contained in vessels. insects have a dorsal vessel with a sort of heart (but is not like that of mammals). insects only transport nutrients and waste and NOT oxygen. for this reason, their circulatory fluid, hemoplymph, is greenish in colour. the cavity in which the hemolymph opens is known as the haemoceal. hemplymph passes into the haemoceal through openings called ostia (sing. ostium)
