There are three major forms of respiratory systems in Arthropoda:
_______________ Aquatic Arthropods, such as the Class _______________, have gills for respiration under water
_______________ Book lungs can be found in the Class Arachnida. Book lungs are made up of stacks of alternating _______________and _______________ tissues, which resemble a closed book. They are connected to the outside world by small openings called _______________.
A _______________: Terrestrial Arthropods such as the Class Insecta have a tracheal system consisting of _______________ and _______________. The _______________ are small openings in the exoskeleton that can be opened and closed to allow gas exchange.
Once oxygen has entered the _______________ it travels along the many _______________ to all of the body tissues.
Internal Transport
Arthropods have an _______________ made up of a large internal cavity called a _______________ that is filled with _______________ (Arthropod blood)
Arthropod blood is used to transport nutrients to the tissues
Arthropods also have a series of _______________ that run along the _______________ side
The hearts pump _______________ from the abdomen to the head through the single Arthropod blood vessel called the _______________
Once the _______________ enters the _______________ it leaves the aorta and moves into the spaces between the tissues (hemocoel).
It then flows back to wash over the _______________ organs
Excretion:

Arthropods have many specialized organs used for sensing and responding to their surroundings
are used to sense and respond to _______________ as well as _______________ and _______________
_______________:

_______________ – Some Arthropods (such as Crustaceans and the Insects) contain special structures called _______________at the base of their antennae that give them a sense of balance
_______________ – Some Arthropods have a membrane found on either side of the _______________ that detects sound vibrations.
VIII Movement
There are many forms of movement seen in the Arthropods ranging from the segmental movement seen in Millipedes to the ability to fly seen in some of the Insects and to the ability to swim seen in some Crustaceans
Due to the rigid _______________ Arthropods must have _______________ in order to move. This is how they have received their name Arthropoda, "Jointed Feet"
Most Arthropods contain many more _______________ than humans that help them perform all of their intricate movements
IX Reproduction
Arthropods are either _______________ or _______________ but not _______________

The fertilized egg is released from the female through an _______________ near the anus
Insects have several life stages:
The _______________
Released from the ovipositor
Contains the embryo
The young insect, which may be either
a _______________ – a young insect which more or less resembles the adult.
or a _______________– a young insect that doesn't resemble the adult form
Larvae have a pupal stage during which they undergo _______________ in order to turn into adults. (Nymphs do not have a pupal stage and do not undergo metmorphosis)
The _______________ The pupa is a nonfeeding stage following the larval stage. An example is the cocoon
