The life history of insects usually exhibit metamorphosis.

Three pairs of legs are attached to thorax region of a cockroach.

The dorsal chamber of the haemocoel is the pericardial sinus which is connected to the heart and gives oxygenated blood.  

insects   The Malpighian tubule system is a type of excretory and osmoregulatory system found in some Uniramia (Insects and Myriapoda),

Insects have malpighian tubules for excretion 

Centipedes (class Chilopoda), cockroaches (class Insecta), and crabs (class Crustacea) are all arthropods, which are characterized by jointed appendages and a hard exoskeleton made of chitin. These two features are universal across all arthropod groups. Compound eyes and book lungs are not present in all arthropods.

Collembola is a very small insect. It directly breathes through its skin by diffusion of gases.

The labium or the lower lip is the largest and most posterior of the mouth appendages.

Hepatic caecae are present in the midgut.

Pulville (cushion-like pads) are present in the posterior part of the gizzard. They have chitinous hair, which acts as a sieve once the food is ground.

6 teeth are present in the gizzard; they facilitate the grinding of food.

The caecae secrete digestive juices and pour them into the stomach.

Peritrophic membrane lines the wall of midgut. The peritrophic membrane serves several functions, including improvement of digestion, protection against mechanical and chemical damage, and serving as a barrier to infection by pathogens.
