Cockroaches can live without Head-Fact or Fiction ?

How long can a roach survive without its Head? The answer is… up to a week! Unlike humans, cockroaches breathe through microscopic pores in each of their body segments, negating the necessity for a mouth or ahead.

Cockroaches are famed for their resilience, and they are generally thought the most likely nuclear war refugees.
Because of their open circulatory system and the fact that they breathe through microscopic holes in each of their body segments, they do not require the mouth or head to breathe.
The Cockroach only dies of thirst because it cannot sip water without a mouth.

This pest has a strong survival instinct. They are still alive despite having lost their heads for a few weeks. The researchers discovered why they can do it but humans cannot.

Furthermore, human breath via the mouth or nose, as well as the brain, governs this function. As a result, when humans lose their heads, their respiration stops. Furthermore, humans cannot feed without their heads and will almost probably die from malnutrition.

Cockroaches, on the other hand, are not necessary to have blood pressure like humans. “Unlike humans, they do not have a broad blood channel network – this implies that the tiny vessels demand a high pressure for circulation.” They have a low-pressure, open circulatory system.#cockroach
