Question

Do cockroaches have blood?

Answer 1

Blood of cockroaches:

1. Cockroaches do, in fact, contain blood.
2. Haemolymph, which is found in the hemocoel, is their blood.
3. Their circulatory system is open, with visceral organs bathing in a blood-filled open chamber termed a hemocoel.
4. Haemocytes and colorless plasma make up the hemolymph, which is colorless.
5. It is not red in color because it lacks hemoglobin, the red respiratory pigment.
6. They do not carry oxygen through the blood; instead, oxygen is transported through diffusion through the tracheal system.
