In male cockroach, a mushroom-shaped gland is present in the 
abdominal segments, and it functions as an accessory reproductive gland, so statement I is correct. Cockroach has an open circulatory system in which blood from the sinuses enters the heart through ostia and is then pumped anteriorly back into the sinuses, making statement II also correct. Hence, both statements are correct.
