What are the differences between cockroaches and human beings?
Answers
Cockroaches can hold their breath for up to seven minutes. Their respiratory system is highly efficient but there are no lungs. Instead, the insects draw in air through external valves called spiracles and transport the air directly to the cells via tubes called trachea.
Respiratory system is one of the most important biological systems in the body of any living organism.
But there are major differences in the biological structures of the respiratory systems of different species.
Similarly,there are also major differences between the respiratory systems of the human and cockroaches.
Such as,
1) Cockroaches have no lungs in their respiratory system but the humans have a pair of lungs in their respiratory system.
2) The air transmission process in the body cells of the cockroach is very simple as compared with the humans.
3) The cockroaches can retain the consumed oxygen for long time than the human.
4) The allover respiration system of the humans are more complex than the cockroaches.

Answer in detail:
There are many ways of course that cockroaches are different than humans, but mostly lets discuss bodies. For instance why do cockroaches die on their backs with their legs in the air? To know the answer to this question is simply to look at them. Cockroaches have rounded backs that are greasy, with a body that is able to be flat. That flat body is what allows them to squeeze in through the cracks in your walls.
Commonly used insecticides induce muscle spasms and can confuse the cockroaches, which of course makes them look like a turtle stuck on their back. Their body oddities are also what allows them to walk up walls whereas of course we humans cannot. Cockroaches have three sets of legs which allow them the ability to go places and do things we can't like walking up a wall or across glass without slipping. Each set of these legs is controlled by their own nerves with a foot like claw at the bottom of the leg. There is no central nervous system like and brain in a human. Cockroaches can live without its head because there literally is no brain in there. If left in the wild, cockroaches typically will stick in groups of up to 50 to try to secure safety.
