Number of Chambers in the Heart of Cockroach is (a) 5 (b) 9 (c) 13 (d) 16

Answer: (c) 13

Cockroaches are pests that live in unsanitary and moist environments. They are dark brown in colour and belong to the Arthropoda phylum, Blattidae family, and Insecta class. The tubular heart of a cockroach has 13 chambers. Each chamber receives oxygenated blood through a pair of apertures called Ostia.

Cockroaches have multi-chambered, tube-like hearts that are far more resistant to failure than human hearts.

Instead of designing the heart like a tube, they’ve made the chambers seem like an onion with a series of concentric spheres.

Cockroaches are members of the phylum Arthropoda’s class Insecta.
