Grasshopper dissection
By Chloe
Introduction
Grasshoppers are complex insects and have many specifics when it comes to
their body systems and functions. Grasshoppers, like all insects, have a
three part body of a head, thorax, and abdomen. They also have compound eyes
like other insects. However, their legs and wings set them apart from others
because of the jumping legs as well as walking legs that they use and the
layer of wings they use to fly. Their segmented bodies are made up of a hard
exoskeleton of tagmata.

Skeletal System
Grasshoppers have a three part body and a hard shell exoskeleton of chitin.
Their three part body contains of a head, thorax, and an abdomen. The
exoskeleton is divided into sections with flexible joints that allows movement
more easily. The joints that the grasshoppers have can be compared to humans
because they allow movement but our connect our bones while the grasshoppers
needs connection of its three tagmata. That is because humans have an
endoskeleton and outer covering is there to protect the organs we have inside.

Circulatory System
Grasshoppers have an open circulatory system where the blood starts at the
hemolymph, travels through large blood vessels, to the coelom, to the abdomen,
and the heart in an open loop. The hemolymph contains chambers called sinuses
which is similar to the heart of humans with four chambers. Their blood
transfers food and waste but not oxygen or carbon dioxide thus it green in
color. When their hearts pump blood, the aorta takes it to the head and the
blood flows openly. The blood also contains no hemoglobin which results in a
different color. Humans have a closed circulatory system of the heart, veins,
arteries, and blood, and the heart pumps blood of nutrients, oxygen and waste
that travels through arteries and veins. Instead of the exchange of carbon
dioxide and oxygen happening through the circulatory system like in humans,
it happens in the tracheal system.
