I really have no idea, it just struck me, and I feel quite ignorant. I know I've had a moan, (see previous question by me, about flies) but what makes up an insect, do they have internal organs, or are they just made up of the mush you generally see when they've made contact with your car windscreen at 50mph?

ur nickname spells out everything..of course they do..
Insects use tracheal respiration with openings on the sides of the thorax and abdomen called spiracles leading to the tubular tracheal system. Air reaches internal tissues via a network of branches from the tracheal system. There is usually one pair of spiracles per segment. There can be up to 8 abdominal segments with spiracles and upto 2 thoracic segments (restricted to the mesothorax and metathorax). Some groups have reduced numbers of spiracles with the hoverflies having none on their abdomen. There is a physical limit to the pressure that the walls of the tracheal tubes can withstand without collapsing, even though they are stiffened by bands of chitin, and this is one of the reasons why insects are relatively small. The spiracles have muscle controlled valves, enabling the insects to avoid drowning in water or to prevent desiccation. The spiracles often have hairs that help filter the air entering them.
they breathe for life like we do but in different ways

Insects do not have lungs. The larger ones breathe through tubes into their body called spiracles and/or smaller tubes called tracheae. Very small insects breathe through their skin using the process known as diffusion.

They don't breathe when they are dead. Insects have internal organs almost like us, they are just smaller and abit different.

Insects have many of the same parts that you do. Only smaller and different. See

Only the ones that are alive. The ones that I squash with my shoe are definitely not breathing anymore.

They do breathe. If it's alive it must breathe.
