Skeletal system
Grasshoppers are divided into three parts: The head, the Thorax, and the Abdomen. The Head consists of the compound eye, antennae, mandibles and the palps. The Thorax consists of the Walking legs, and the Abdomen consists of the spiracles, wings and jumping legs. Grasshoppers have a hard chitinous exoskeleton which is divided into sections with flexible joints that allow easy movement. The chitinous exoskeleton is an advantage for the grasshopper because it joins the abdomen, thorax and head (Punjoo). It also prevents loss of body water.
digestive system
Just like humans, grasshoppers need food and water to survive too. Their digestive system, however, is really different from ours. For example, grasshoppers have a crop and a gizzard and humans do not. The food enters through the mouth, where it is then sent in to the Esophagus, an organ of which the function is to send food from the mouth cavity to the crop. The Crop is an organ which is used to store food and is not found in Humans. The food then goes to the Gizzard, the organ that breaks down food and is also not found in Humans. After being processed, the food is chemically broken down in the Gastric Caeca; it is then sent to the Stomach in which enzymes are produced to further break down the food. Nutrients are gathered from the intestine from the food as the food brings its way further; it is then sent to the Rectum to have all the water in it absorbed. Finally, the food is excreted out from the anus and the cycle continues to go along as long as the grasshopper keeps eating.
respiratory system
Although the Respiratory system may seem to be the same as a Human, I find it to be quite unique/interesting in a grasshopper. Instead of breathing in air, grasshoppers use tiny holes located on their abdomen called Spiracles; the Spiracles are located along both sides of the abdomen and are used to bring air into the grasshoppers body. From there the air is sent down the trachea where oxygen is sent to the heart. The air then goes to the Malpighian tubes where all the nitrogenous wastes in the air are removed from its body. Air keeps on coming in through the spiracles and the system keeps on going.
cardiovascular system
Unlike humans who have a closed circulatory system, grasshoppers have an open circulatory system. Another difference is that while humans have blood exchange through their cardiovascular system, grasshoppers have it through their respiratory system. Grasshoppers just like many other insects, do not have blood; instead, they have EDIT IT
nervous system
While grasshoppers are invertebrates, meaning they don't have a backbone, they still do have a brain. Grasshoppers have very specialized eyes called 'Compound Eyes,' and they are much more effective than human eyes. Grasshoppers use their antennas to sense things in the environment. Like humans, grasshoppers have a central nervous system and it consists of the brain and the ventral nerve chord (it's sort of like a spine, except it isn't a bone). The nerves from the grasshoppers connect to the compound eye and the antennae. Grasshoppers also have mandibles which they use as their mouth.
