Answer:
The circulatory system of cockroaches is the open circulatory system
Explanation:
In cockroaches, the circulatory system is not as developed as is in higher animals. The cockroach has an elongated tubular heart with aorta and sinuses making up its circulatory system.
The hemolyph (blood) is directly supplied to the body tissues unlike in higher animals that depend on elaborate blood circulation systems that have blood vessels. The hemolyph baths the tissues of the of the body of the cockroach
It is from this hemolymph that the tissues of the body of the cockroaches get their nutrients. Oxygen to the tissues is supplied by a separate well structure respiratory system.
